Gas Type Correction Factor «CHANNEL MENU«On total pressure transmitters which employ a measuring method which is independent of thetype of gas, a correction factor for matching to various gases can be assigned to thetransmitter. This will ensure that the pressure display is corrected in a broad pressure range.On a combi-transmitter such as, for example, the. HPT 100 with differing measurementmethods two correction factors are necessary (see the operating instructions for thetransmitter).For the CPT100, PPT100 and RPT100 only one correction factor is settable.

18

Retro-Adjustment «CHANNEL MENU«With the help of the DPG 109 retro-adjustment can be carried out on the transmitter.When carrying out a zero point equalization ensure that the pressure in the vacuum chamberis at least one decade below the measuring range of the transmitter.

The connected transmitterrequires a warm up phase ofat least 5 minutes. Do notsubject the transmitter tolarge pressure fluctuationsbefore equalization.

➡ Depress “set“ key in "CHANNEL MENU"until the cursor flashes in the menu point»aaddjjuusstt«.

➡ Depress the “Up“-key; in the displaythere appears on the cursor position thedisplay »HI«.

To equalize the transmitter tothe daily pressure ensure thatthe pressure on thetransmitter is between 600 Torr and 900 Torr.

➡ After depressing the “set” key thereappears in the display the pre-setreference pressure value (*)/(**).

➡ With the “Up-/Down“ keys set the actualreference day pressure (**).

➡ By depressing the “set“ key the newvalue is taken up and the cursor jumpsback to the actual channel number »ch:«.

➡ Set the reference pressure value in thesame way for the zero point equalization»LO«.

When equalizing to the zeropoint »LO« ensure that thereference pressure in thevacuum chamber is at leastone decade below the measu-ring range of the transmitter.☞

(*) The reference pressure value can only be entered in the measurement units mbar, hPa orTorr. If, for example the unit bar is selected, for reference pressure input purposes there is atemporary switch over to mbar, withTorr to Torr and with Pa to hPa. When equalization hasbeen completed the originally selected display unit is again active. (**) These points are only required for daily pressure equalization on the CPT100 and theRPT100 .

Degassing «CHANNEL MENU«With total pressure transmitters employing the hot cathode measurement system (HPT100) itmay be necessary to bake out the sensor anode in ultra high vacuum in order to clean theadsorbed gas particles and thereby to minimize gauge head degassification.

Activating the degas function:➡ Depress the “set“ key in "CHANNEL

M E N U" until the cursor in the menu point»degas« flashes; the actual status of thedegas function will be displayed (»off« or»on«).

➡ Using the “Up“ key select the function»on«.

➡ Start the degas procedure with the „set“key.

The degas process lasts for approx. 3 minu-tes. During this time no measurements arepossible on this channel .In the menu point»PRESSURE« there appears for this chan-nel number the display »degas«. When thedegas time has been completed the displayautomatically jumps back to the pressuredisplay.

The degas process can be manually de-activated at any time by switching the degasfunction to »off«:➡ Depress the “set“ key in "CHANNEL

M E N U" until the cursor flashes in themenu point »degas«.

➡ Select the function »off« with the “down”key.

➡ Switch off the degas process with the“set“ key.

➡ After selection of this menu via the key"Menu" the cursor flashes on the position»rel:« (Relay number).

➡ Select the required relay numbers withthe "Up" and "Down" keys.

➡ Take over the relay with the “set“ key .➡ Assign channel numbers with

the"Up"/"Down“ keys under the menupoint »chann« :– »off«: Relay switches off independently

of the set/actual comparison. – »on«: Relay switches on independently

of the set/actual comparison.– »1« to »9«: Relay switches according to

the pressure value of this selectedchannel.

Each relay can be assigned to each of the 9transmitter channels .It is also possible tolink several relays with only one channel.

➡ With the “set“ key take over the channel.➡ Alter to the required threshhold value

with the Up-/Down keys in the menu point»press«.

➡ Take over the threshhold value with the“set“ key.

➡ Proceed in the same manner for themenu point »hyst«.

The hysteresis is symmetric tothe switchpoint. Altering theswitchpoint will cause therelated hysteresis to bematched automatically via apercentage relation to the newthreshhold value.

Example:Previous setting: SP1 ==> 20 TorrHyst. ==> 2 Torr

(= 10%, that means switch off point 18 Torr, switch on point 22 Torr).

New threshhold value:SP1 ==> 400 Torr neue Hyst.. ==> 40 Torr.
