Safety Memory gauges are pressure tools. If careful procedures are not followed, pressure

could be trapped inside the tool and the dismantling operation could become dangerous.

Memory gauges are designed for and can be run in a sour gas environment. Usual

maintenance and safety practices for sour service equipment must be followed in order to protect personnel using the tool and to ensure the longest possible tool service life.

Memory gauges use lithium battery packs, which have special handling and disposal

procedures. If the following recommendations are not clear or in case of doubt, please contact

Metrolog at: Tel: + 33 5 61348074 Fax: + 33 5 61348066 Email: [email protected] It is assumed that all relevant safety aspects, precautions and recommendations

are known by the operators using Metrolog gauges. Pressure As any downhole tool, a memory gauge can trap pressure. While every precaution

must be taken to insure that pressure cannot enter in the gauge by: - regularly changing the O-rings, - always cleaning the O-ring grooves before installing new O-rings, - using the right O-ring type for a given environment, - maintaining the HPC contact’s O-rings, - from time to time, tightening the quartz crystal sensor on its holder with a

dynamometric range, (see the following sections for more details), it is always possible to face the rare event that pressure entered in the tool but did not get out. It is particularly true in gas wells when the gauge has been left for a long time in the well: pressure could enter slowly by migrating through the O-rings but does not have time to bleed-off when the gauge is retrieved.

Most of Metrolog memory gauges are built for this problem not to happen: either

the pressure or the temperature probe of the AMEtrolog, TAMEtrolog, Flolog and Multilog will be pushed out of their seat if pressure inside the tool becomes higher that the outside pressure. CGMs, by their design, cannot incorporate such a safety feature.

Metrolog proposes, for CGMs, a special electronics housing with a built-in relief valve. This relief valve must be maintained in perfect condition to be efficient.

When gauges must be exposed to gas for a long period of time, it is advisable to

run them inside gauge carriers full of high temperature oil (i.e. silicone oil) in order to avoid or limit the gas migration through the O-rings. Metrolog proposes these carriers for its different gauges.



In extreme cases, for very long duration operation in gas wells, Metrolog proposes

Fully-Welded CGM gauges. These CGMs do not have any O-ring and thus are the only solution for very long exposure to gas.

However, and except when Fully-Welded CGMs have been used, all the above

precautions may not be sufficient to prevent pressure to enter the gauge. Strict procedures must thus be followed.

When pressure is trapped in a memory gauge, two possible symptoms must alert

the user: - the HPC sleeve is extremely hard to move and even stuck and - the electronics housing is very hard to move and its locking screws are hard to remove. Caution!! These symptoms are not exhaustive and pressure could be trapped in the gauge without any evidence of such a problem.

WARNING A highly possible danger comes from the HPC contacts that could be expelled with a great force when the HPC sleeve is moved. The HPC contacts are glued in place but just to keep them in their seat not to resist to high internal pressure.

When moving the HPC sleeve, do not stand in front of the HPC contacts. Check their position before moving the HPC sleeve: they are on the same axis that the serial number visible on a flat surface when the HPC sleeve is in its up position.

WARNING Try to open the electronics housing first. In this case, all precautions must be taken to avoid the housing to be ejected violently (for the same trapped pressure, the force pushing on the housing is 10 times higher that the force pushing on the HPC contact.

When removing the electronics housing, do not stand in the alignment of the tool.

Sour service All Metrolog's memory gauges have been designed to be run in sour service

environment but, in this case, O-rings must be changed between every run and the bottom nose filled-in with high temperature grease.

The CGM has a built-in bellow, which protects the quartz sensor against the well

fluid. Complete buffer tube adapters or special bottom noses with a built-in buffer tube

are available on request for sensor protection.



Battery safety Lithium batteries used by Metrolog memory gauges are Lithium based batteries

that are a potential hazard in case of wrong usage or wrong operation. We thus advise the users to observe particular precautions when using Lithium batteries, such as:

1. Do not use batteries above their temperature l imit. 2. Do not open the batteries in order to prevent any risk of short

circuit. 3. Do not introduce a metall ic or conductive object in the battery

connector in order to prevent any risk of short circuit. 4. Do not throw them in f ire. 5. Do not open them. 6. Do not try to recharge them. 7. Do not put them under any pressure or stress that could deform

them. 8. Do not knock on the batteries in order to depassivate them. If

needed, use the depassiver supplied by Metrolog.

WARNING In most of the countries, strict regulations apply for the disposal or the destruction of Lithium batteries. Please contact special ized companies or Metrolog.

In order to protect the users, these batteries are equipped with a double level of

fuse. One fuse is built in the cell itself, a second fuse has been added at Metrolog's request by the battery manufacturer. However, it is important to understand and respect the above rules and to treat these batteries with special care with a full understanding of their specificity; the protection by fuses is of no use in case of deformation or crushing of a battery by a mechanical action.

If you have any question or doubt, please contact Metrolog.

WARNING Before use, carefully check the maximum temperature of the selected battery and compare it with the expected downhole temperature.

1 x15 (E15, E15E, H15, J15, F15, F15E, 2F15E, etc..) batteries are limited to

150 °C or 300 °F. 2 x18 (E18, F18, etc..) batteries are limited to 180 °C or 350 °F.

Replacement of O-rings The O-rings generally supplied by Metrolog are Viton O-rings 90 Duro. When replacing the O-rings, it is important to follow strict procedures in order to

achieve the proper seals and their longevity: 1. Apply the minimum possible stress. Pass the O-rings around the smaller

diameter possible. 2. Because of the inevitable stress applied when installing new O-rings, once

installed, wait 2 minutes before placing the housing that will cover them. This gives time for the O-rings to relax and to take back their original shape.

3. Metrolog recommends not to use back-up rings anymore. Wherever an O-ring and a back-up ring were used, install two O-rings of the same

size in the same groove instead. (Figure M1 - O-rings installation)

WARNING Special O-r ings for operations in gas wells For long or multiple exposures to gas, it may be needed to replace the standard

Viton 709/90 O-rings by special O-rings made of other compounds or harder Viton like Viton 858/95

These O-rings have been designed to resist to explosive decompression and are

used by major oil producing companies in gas fields for downhole and surface applications.

Their main characteristic being to have a very low permeability to gas, they greatly

reduce the gas entry (by diffusion) into the gauge. Same replacement precautions apply than for standard Viton O-rings. In order to determine which compound is best adapted to each application,

contact Metrolog and supply the fluid characteristics and chemical content.



HPC sleeve O-rings on 1.25" OD AMEtrolog (8000 < serial number < 8300) (Figure M2 - 1.25" OD AMEtrolog parts description) The HPC sleeve O-rings are to be changed frequently since the HPC sleeve will be

moved at each run and because they protect the HPC contacts. On AMEtrologs, the HPC sleeve O-rings are changed without opening the gauge by

removing the bottom adapter: 1 Put the gauge on a flat surface. Pull the HPC sleeve in the down position

(uncovering the 2 HPC sleeve O-rings). 2 Remove the locking ring screw. Then remove the bottom nose, the bottom

nose adapter and the locking ring by unscrewing the bottom nose adapter. 3 Remove the locking O-ring, the HPC sleeve and the HPC sleeve O-rings. 4 Place new O-rings (n° 022) by sliding them around the sensor holder. Grease

them with lubriplate grease. 5 Replace the HPC sleeve, slide it in the up position and replace the locking O-

ring (n° 022) around the sensor holder. 6 Replace the locking ring and re-assemble the bottom nose and bottom nose

adapter by screwing them to the sensor holder. Replace the locking ring screw and tighten it gently.

HPC sleeve O-rings on 1.25" OD AMEtrolog CC (serial number > 8300) (Figure M3 - 1.25" OD AMEtrolog CC parts description) On AMEtrolog CC gauges, a similar procedure must be followed. However, since

AMEtrolog CC do not have locking ring and do not use n° 022 O-rings for the HPC sleeve, the procedure becomes:

1 Put the gauge on a flat surface. Pull the HPC sleeve in the down position

(uncovering the 2 HPC sleeve O-rings). 2 Remove the locking screw. Then remove the bottom nose and the bottom

nose adapter by unscrewing the bottom adapter. 3 Remove the locking O-ring, the HPC sleeve and the HPC sleeve O-rings. 4 Place new O-rings (n° 118) by sliding them around the sensor holder. Grease

them with lubriplate grease. 5 Replace the HPC sleeve, slide it in the up position and replace the locking O-

ring (n° 022) around the sensor holder. 6 Re-assemble the bottom nose and bottom nose adapter by screwing them to

the sensor holder. Replace the locking screw and tighten it gently.



Electronics housing O-rings on 1.25" OD AMEtrolog (8000 < serial number < 8300) The electronics housing O-rings must be changed regularly above all if the gauge is

used in gas environment or in corrosive fluids: 1 Put the gauge on a flat surface. 2 Remove the four electronics housing locking screws and remove the

electronics housing with great care using the tip of a screw driver to start moving slowly the O-rings from their seal bore.

3 Disconnect the battery by pulling it while holding firmly the gauge top

connector with the other hand, in order not to apply tension on the circuit boards. Remove the old electronics housing O-rings.

4 Place new housing O-rings (n° 118) by sliding them around the electronics and

grease them. 5 Reconnect the battery and slide the electronics housing back in place with the

same care than for removing it. Place and tighten the four electronics housing screws.

Electronics housing O-rings on 1.25" OD AMEtrolog CC (seria l number > 8300) On AMEtrolog CC gauges, a similar procedure must be followed. However, since

AMEtrolog CC use a truarc to hold the battery in place the procedure becomes: 1 Put the gauge on a flat surface. 2 Remove the four electronics housing locking screws and remove the


3 Remove the battery locking truarc, disconnect the battery by pulling it while

holding firmly the gauge top connector with the other hand. Remove the old electronics housing O-rings.

WARNING Precaution to be taken before every Multilog run In addition to the regular change of O-rings, the Multilog needs a special treatment

before each job: the spinner holder needs to be filled with light fluid in order to insure lubrication and to prevent fluid entry that could stop the spinner rotation.

To fill the spinner holder, just before a job: 1 Remove the injection screw with a 7/64" Allen key from the Multilog body. 2 Place the Multilog upside down and fill the spinner holder with light, non greasy

fluid (kerosene or light fuel) using a syringe for example. 3 When the fluid flows from the spinner, the spinner holder is full. Replace the

injection screw and tighten it.



Sensors holder O-rings on 1 11/16" Multilog (Figure M9 – Spinner assembly detail) To change the sensors holder O-rings on a 1 11/16" Multilog: 1 Put the gauge on a flat surface. 2 Remove the four body locking screws with a 9/64" Allen key. Pull apart the

Multilog body and the sensors holder. 3 Remove the four sensors holder O-rings by cutting them (and if necessary the

two pressure isolation O-rings). 4 Place by sliding them around the sensors holder: - the new sensors holder O-rings (n° 123) and - eventually the new pressure isolation O-rings (n° 124). 5 Replace the Multilog body on the sensors. Place and tighten the four body

locking screws. Sensors holder O-rings on 1.5" Multi log (Figure M12 – 1.5" Flolog spinner assembly detail) To change the sensors holder O-rings on a 1.5" Multilog: 1 Put the gauge on a flat surface. 2 Remove the four body locking screws with a 9/64" Allen key. Pull apart the

The following maintenance procedures are relatively rare and should only be

performed in the lab. Spinner assembly O-r ings on Multilog (Figure M9 – Spinner assembly detail) (Figure M12 – 1.5" Flolog spinner assembly detail) To change spinner assembly O-rings on a Multilog: 1 Remove the Multilog cage by unscrewing it with the necessary precautions to

prevent deforming it. 2 Remove the two cage locking O-rings. Remove the spinner holder locking

screw (or at least unscrew it enough to free the spinner holder) with a 1/16" Allen key and unscrew the spinner holder with a 126A.35 C spanner.

3 Remove the spinner holder O-ring and replace it by a new one (n° 015). 4 Replace the spinner holder and tighten it with the 126A.35 C spanner. While tightening the spinner holder, check that the spinner is rotating freely. If

it is blocked, unscrew the spinner holder of a 1/4 of turn to recover free rotation. Once the spinner holder is in the correct position, replace and tighten the spinner holder locking screw.

5 Replace the two cage locking O-rings, then the Multilog cage and tighten it

with the necessary precautions to prevent deforming it. Temperature sensor O-rings on Multi log (Figure M9 – Spinner assembly detail) (Figure M12 – 1.5" Flolog spinner assembly detail) To change temperature sensor O-rings on a Multilog: 1 Pull on the temperature sensor in order to remove it from its location but with

extreme precautions in order to prevent to break the connecting wires. 2 Remove the two temperature sensor O-rings. 3 Place the new temperature sensor O-rings (n° 007) by sliding them around

the temperature sensor. 4 Push the temperature sensor back in place. Please note that TAMEtrolog uses n° 011 O-rings instead of n° 007.



Tightening the quartz sensor and its bellow on quartz sensor holder (Figure M6- CGM quartz sensor holder detail)

WARNING The CGM Quartz sensor does not need any maintenance. However, from time to time it may be needed to tighten the quartz sensor and its bellow on the quartz sensor holder since the connections could become loose due to vibrations. This operation can only be performed in an electronic lab by an experienced technician. The following procedure is then to be followed.

To tighten the quartz sensor and its bellow on the quartz sensor holder (this

operation must been done with great care not to damage the sensor electrical connections):

1 Put the gauge on a flat surface. 2 Remove the bottom nose by unscrewing it. Remove the CGM bottom nose

adapter locking screw and remove the CGM bottom nose adapter by unscrewing it. If too tight, remove one of the quartz sensor holder screws and use a C-spanner to unlock it.

3 Remove the four quartz sensor holder screws.

WARNING The sensor housing and the quartz sensor holder can only be pulled apart for a few centimeters, just enough to uncover the O-rings and the sensor bellow nut.

It is not possible to extract the sensor. Do not over-pull as it wil l damage or break the sensor electrical

connections. 4 Slide with great care the quartz sensor holder to uncover its O-rings, the

sensor bellow and the quartz sensor nut, using the tip of a screw driver to start moving slowly the O-rings from their seal bore.

5 Remove the old O-rings and place new quartz sensor holder O-rings (n° 118)

by sliding them gently around the upset.

6 Tighten the sensor bellow on the quartz sensor holder and the quartz sensor on its bellow with a dynamometric range at 25 lbs.ft or 3.46 m.daN.

WARNING Since the O-rings deformed to pass the upset, wait 2 minutes for the O-rings to recover thei r normal shape.

7 Slide the quartz sensor holder back in place with the same care than for

removing it. Place and tighten the four quartz sensor holder screws. 8 Re-assemble the CGM bottom adapter and tighten its locking screw. Re-

assemble the bottom nose.



Maintenance of HPC contacts The HPC contacts must be kept clean at all times. Do not clean them with a sharp

object nor with a metallic tool but with cloth or cleaning paper. There is no other routine maintenance on the HPC contacts than cleaning. However,

HPC O-rings must be changed before long term jobs.

WARNING HPC contacts also have 2 O-rings (n° 011) which are replaced during major repairs only. Since the HPC contacts are glued in place for safety reasons, the procedure below is usually performed at Metrolog's. We give it for reference and for emergency action.

The following procedure must never be performed in the field but only

in an electronic lab by an experienced technician. Use exclusively high quality O-rings for the HPC contacts. Refer to "Special O-rings for operations in gas wells" higher in this section. (Figure M10 - HPC contacts detail) 1 Strip the gauge as much as possible, following one or more of the procedures

described above, in order to work on the part holding the HPC contacts only. 2 Heat the HPC contacts with a hot air blower for example, up to a temperature

of 150°C (300 °F). 3 When the part holding the HPC contacts and the HPC contacts are hot, insert

the tip of two small screwdrivers in the HPC contact groove and pull firmly to remove it. Do not pull by more than a few centimeters not to break the electrical connections.

4 Clean the bottom of the HPC contact seat. Remove first all traces of glue with

a metallic tool without damaging the seal bore. Clean it then with an industrial cleaner, for example: Loctite 7063

5 Replace the 2 HPC contact O-rings on each contact carefully, to avoid cutting

the connection wire on the sharp edges of the HPC holes. 6 Glue the HPC contacts back in place using high temperature metal-metal glue,

for example: Activator Loctite 7649 Glue Loctite 648 Press firmly each HPC contact in its seat during a few seconds, checking that

each contact has reached the bottom of its seat in order for the HPC sleeve to travel freely above it.

7 Replace all O-rings and all other mechanical parts and re-assemble the gauge.



Maintenance of special CGM housing relief valve When a special CGM housing with relief valve is used, the status of the relief valve

must be checked after each run. The relief valve rod must be flush with the bottom of the relief valve nut. If the relief valve rod has popped out, it means that the gauge internal pressure was greater than the outside pressure and that the relief valve has completed its task.

(Figure M11 – CGM housing relief valve detail).

WARNING It is extremely important to redress the relief valve as f requently as possible and in any case each time the relief va lve rod has been found out of i ts seat.

To redress the CGM housing relief valve: 1 Make sure the rod is pushed back in order to introduce a 5/16" Allen key

inside the relief valve nut. Unscrew the relief valve nut. 2 Pull the relief valve rod and spring out.

8 Place two new O-rings (n° 011).

9 Replace the relief valve rod and push it down in its seat, replace the relief valve spring and nut. Tighten the relief valve nut with the 5/16" Allen key.

10 Check that the relief valve rod is flush with the bottom of the relief valve nut.

Spinner and cage definition for Multi log Multilog gauges can be used with various cages and spinners according to the

minimum ID of the completion in which they will be run and to the maximum flow velocity expected.

Four sizes of Multilog cages are proposed: 1.5" cage for 1.5" OD Multilog, 1 11/16", 2 1/8" and 2 7/8" cages for 1 11/16" OD Multilog. This size is the outside diameter of the cage and must be selected according to the Multilog size and the minimum ID of the completion. Please note that a 1.5" OD Multilog can only measure flow and fast response temperature or pressure and fast response temperature. Two spinner pitches are proposed: 2" and 5". The pitch represents the fluid movement when the spinner makes one complete revolution. According to the expected fluid velocity, the spinner must be chosen with the following limits: - minimum measurable velocity: 1 Hz = 1 revolution per second and - maximum measurable velocity: 100 Hz = 100 revolutions per second.

The following table gives the part number for each part or each kit. Description Part number For 1.5" OD Multi log only 1.5" OD cage D.30.A.CAG0 2" pitch spinner for 1.5" OD cage D.30.A.SP20 Kit with 1.5" OD cage and 2" pitch spinner D.30.A.FK20

Metrolog SAFETY, MAINTENANCE AND TROUBLESHOOTING MANUAL November 2007 --------------------------------------------------------------------------------------------------------------------------------------------------------- Section 3 Troubleshooting ---------------------------------------------------------------------------------------------------------------------------------------------------------


Troubleshooting with PC The symptoms are not presented by order of importance but chronologically as

they may happen during the use of the gauge. Some may me obvious, some more complex.

It is assumed that the operator is following the standard procedure to access the gauge (for programming or reading) with the PC.

The gauge cannot be neither "stopped and tested" nor read Symptom: After clicking the 'Stop & Test' icon or the 'Read Data' icon, the

message "Gauge Communication Failure, Gauge not Communicating" is displayed on the screen.

Reasons: There is no communication between the PC and the gauge for one or more of the following reasons:

#1: The communication port is erroneous. Solution: Check the port to which the HPC cable is connected it must be a

serial 9 pin RS-232 port. Check that it is the port indicated in the Configuration|System menu.

#2: The HPC cable is not properly connected to the computer or the

gauge. Solution: Check the connections by disconnecting the connectors and re-

connecting them. In particular, on gauge side, check that the contacts are clean and in good condition, that the guiding pin of the HPC connector is in place and so that it was not possible to connect it upside down. Check also that the HPC sleeve is well pulled down and that the HPC connector does not rest on its edge but rests flat on the gauge body itself.

#3: The HPC battery is flat. Solution: Replace the battery by a new 9V battery. #4: The HPC cable has failed. Solution: Use another HPC cable to determine for sure the reason of the

failure. #5: The gauge battery is highly passivated. Its voltage does not reach

the minimum voltage to start the gauge. Solution: See later in this section for the depassivation of a highly passivated

battery. #6: The gauge battery is flat or missing. Solution: Replace it by a new battery if it is to run a job. To read the gauge

data, disconnect the HPC extension from the HPC cable and connect the HPC cable directly to the gauge battery connector in place of the battery. The HPC cable now supplies current directly to the gauge.

#7: The gauge communication system has failed. Solution: Try to access the gauge with a GTI+PM (see below). See below

"Electronics troubleshooting". DO NOT TRY TO REPROGRAM IT IF THERE IS DATA STORED INSIDE.



Communicat ion stops during data reading Symptom: After clicking the 'Read Data' icon, the PC starts reading the gauge,

but after a while the message "Gauge Communication Failure, Gauge not Communicating" is displayed on the screen.

Reason: The HPC battery or the gauge battery is nearly flat. Solution: Replace the HPC battery by a new 9 V battery. If the symptom still

exists, replace the gauge battery. If no new gauge battery is available (at well site for example),

remove the gauge battery, disconnect the HPC extension from the HPC cable and connect the HPC cable directly to the gauge battery connector in place of the battery. The HPC cable now supplies current directly to the gauge.

The gauge does not start after programming Symptom: After programming the gauge, the message "Gauge Communication

Failure, Gauge not Communicating" is displayed on the screen. Reason: The gauge battery is highly passivated. Its voltage does not reach


battery. Symptom: After programming the gauge, the message "Testing Battery" is

displayed on the screen. Reason: The gauge battery is passivated. Its voltage is too low to start data

acquisition Solution: Try again to program the gauge. If unsuccessful, see later in this

section for the depassivation of a highly passivated battery.



Troubleshooting with GTI+PM The symptoms here are not presented by order of importance but chronologically

as they may happen during the use of the gauge. Some may me obvious, some more complex. It is assumed that the user follows the standard procedure to access the gauge (for programming or reading) with the GTI+PM.

GTI+PM does not switch On Symptom: After pressing the "Listen to Gauge" or the "Stop & test gauge"

key, the GTI+PM LED's do not light On or only flash. Reason: The GTI+PM batteries are flat or missing. Solution: Place or replace the GTI+PM batteries with four new 1.5 V AA

batteries. or: The finger pressure on the key is not long enough. Solution: Press at least 1 second on the key for the GTI+PM to start. GTI+PM does not 'Stop & Test' the gauge Symptom: After pressing the "Stop & test gauge" key, the message

"Unauthorized function" is emitted. Reason: The gauge has been programmed 'Not accessible by GTI'. Solution: The gauge can only been stopped and tested by a PC. Symptom: After pressing the "Stop & test gauge" key, the message "GTI is not

accessing the gauge" is emitted. Reasons: There is no communication between the GTI and the gauge for one

or more of the following reasons: #1: The HPC connector is not properly connected to the gauge. Solution: Check the connection by disconnecting the connector and re-

connecting it. In particular, check that the gauge HPC contacts are clean and in good condition, that the guiding pin of the HPC connector is in place and so that it was not possible to connect it upside down. Check also that the HPC sleeve is well pulled down and that the HPC connector does not rest on its edge but rests flat on the gauge body itself.

#2: The gauge battery is highly passivated. Its voltage does not reach


battery. #3: The gauge battery is flat or missing. Solution: Replace it by a new battery. #4: The gauge communication system has failed or the GTI+PM has

failed. Solution: Try to access the gauge with a PC (see above). See below




GTI+PM does not start the gauge Symptom: After pressing the "Start Gauge" key, the gauge does not start (and

the vocal message "The gauge is On" is not emitted ). Reasons: The GTI+PM is unable to start the gauge for one or more of the

following reasons: #1: The memory is full. Solution: Read the gauge first or make sure the gauge has been read. Then

re-program the gauge. #2: The gauge battery is low or passivated. Solution: See later in this section for the depassivation of a highly passivated

battery. Symptom: After pressing the "Programme Validation" key twice (according to

the normal procedure), the gauge does not start (and the vocal message "The gauge is On" is not emitted ).

Reason: The gauge battery is low or passivated. Solution: See later in this section for the depassivation of a highly passivated

battery. GTI+PM does not 'Listen to gauge' Symptom: After pressing the "Listen to Gauge" key, the message "GTI is not

accessing the gauge" is emitted. Reasons: There is no communication between the GTI and the gauge for one

or more of the following reasons: #1: The HPC connector is not properly connected to the gauge. Solution: Check the connection by disconnecting the connector and re-

connecting it. In particular, check that the gauge HPC contacts are clean and in good condition, that the guiding pin of the HPC connector is in place and so that it was not possible to connect it upside down. Check also that the HPC sleeve is well pulled down and that the HPC connector does not rest on its edge but rests flat on the gauge body itself.

#2: The gauge is not On. Solution: Press the "Stop & test gauge" key instead. #3: The gauge battery is low or passivated. Solution: See later in this section for the depassivation of a highly passivated

battery. #4: The gauge battery is flat or missing. Solution: Replace it by a new battery. #5: The gauge communication system has failed or the GTI+PM has

failed. Solution: Try to access the gauge with a PC (see above). See below




Depassivation of a highly passivated battery Symptom: The battery is not able to start a gauge. Note: It is extremely difficult to make a difference between a flat battery

and a highly passivated battery. Both give the same low voltage when loaded. A battery that will not improve after the depassivation procedure must be considered as flat.

Reason: The battery has been stored for a long time or it has not been used quickly after the last operation or it has been disconnected from the gauge (or the gauge has been stopped) before the battery had cooled down.

Solution: Use the depassivation tool supplied by Metrolog. Connect the depassiver corresponding to the battery for a few minutes.

For 10.5 V batteries (E or H), the battery indicator should reach the green zone after a few minutes.

For 7 V batteries (F or J), the battery green LED should be On after a few minutes.

If a battery does not depassivate after a few minutes, there is no

need to persist and the battery must be disposed.

WARNING There is no need to and you should not depassivate a battery based on Electrochem cells.

Battery with Electrochem cells can be recognized by the E after their name: F15E for example.

Depassivating such a battery can even be dangerous. See also the procedure described in the MetroWin help file.



Electronics troubleshooting A few checks can be performed in the field if communication with a gauge is

impossible. The procedure below shows how to detect a broken wire or a broken clock quartz. If all these checks do not locate the source of the problem, please contact Metrolog.

(Figure T1 – AMEtrolog wiring) (Figure T2 – CGM wiring) (Figure T3 – 1" OD AMEtrolog wiring) (Figure T4 – Multilog wiring) (Figure T5 – HPC contacts wiring) (Figure T6 – Gauge connector wiring) For all the below checks, the gauge must be open and the MetroWin software

must be running on a PC. Symptom: There is no communication with the gauge with the HPC interface

cable. The gauge communicates with the GTI+PM. All other possible reasons have been eliminated by going through the 'Troubleshooting with PC' procedure as described above.

Reason: The HPC cable has failed or an HPC interface cable wire is broken. Action: Connect the HPC interface cable to the PC. Do not connect it to the

gauge since this check is performed on the cable alone. Connect the two probes of a voltmeter to the two pins of its HPC plug.

Check that a 12 V pulse appears during at least 1 s when clicking the 'Stop & Test' icon.

If it does not appear, check all wire connections between the RS232 plug and the HPC interface box and between the HPC interface box and the HPC plug.

Symptom: There is no communication with the gauge through the HPC

contacts. The gauge communicates through the battery connector. Reason: A wire connecting an HPC contact to the circuit board is broken. Action: Check the integrity of the HPC connection wires by checking them

with an ohmmeter between the HPC contacts and the circuit board.



Symptom: There is no communication with the gauge. All other possible

reasons have been eliminated by going through the 'Troubleshooting with PC' procedure as described above.

Reason #1: A wire connecting the battery to the circuit board is broken. Action: Disconnect the battery from the gauge. Check the integrity of the

gauge connector wires by checking them with an ohmmeter between the gauge connector and the circuit board.

Re-soldering the wire or replacing it would generally solve the problem.

Reason #2: The clock quartz is broken (generally after a very strong shock). Action: Connect the gauge, connected to its battery (depassivated), to the

PC via the HPC interface cable. If no battery is available, connect the interface cable in place of the battery by removing the HPC extension (see the MetroWin help file for detail).

Use an oscilloscope with a 10:1 ratio probe (or a frequency meter). Connect the oscilloscope ground to the circuit board ground (JP7) and touch one of the leg of the clock quartz with the oscilloscope probe. Click the "Stop&Test" icon: a 1.843 MHz frequency should be measured.

If the frequency does not appear, replace the clock quartz

(D.00.M.QZ1). The new clock quartz must be placed on a thin layer of silicone foam

(for shock absorption) and held in place mechanically. Its legs must be protected with Teflon isolation tubing and must be bent in a way to prevent any contact (short circuit) with the electronics housing.
