If this equipment is used in a manner not specified by 3M, the protections provided by the equipment may be impaired.

Explanation of Signal Word Consequences

m Warning: Indicates hazardous situation which if not avoided, could result in death or serious injury.

m Caution: Indicates hazardous situation which if not avoided, could result in minor or moderate injury.

Explanation of Product Safety Label Symbols

Do not throw away in normal trash.

c Warning: Risk of electric shock

m WARNING

This WARNING applies to the following 3M Dyna-Couplers;• 3" (75 mm) - Part number 3001• 4.5" (114 mm) - Part number 4001• 6" (150 mm) - Part number 1196• All accessory kits containing any of the listed Dyna-Couplers - Part numbers 3019, 4519,

1196/CA potential for electrical shock exists when using the Dyna-Coupler on cables energized with electrical power. Use appropriate safety procedures.DO NOT USE ON CABLES CARRYING IN EXCESS OF 600 VOLTS RMS.

78-8130-6150-0-F 7

m WARNING

This WARNING applies to the use of the Direct Connect Cables and the Transmitter.To avoid potential shock, or electrically damaging the Transmitter, when setting up the Transmitter to locate using the Direct Connect method, follow these basic steps;• ALWAYS plug the Direct Connect Cable into the Transmitter Output Jack [T-6] BEFORE

connecting the leads to the cable/pipe to be located and the ground rod. – Connect the red lead to the cable/pipe. – Connect the black lead to ground rod.A POTENTIAL FOR ELECTRICAL SHOCK, AND/OR TRANSMITTER ELECTRICAL DAMAGE, EXISTS WHEN USING THE DIRECT CONNECT CABLE ON CABLES ENERGIZED WITH ELECTRICAL POWER IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED. USE APPROPRIATE SAFETY PROCEDURES.CHECK VOLTAGE BEFORE CONNECTING TRANSMITTER. VOLTAGE HIGHER THAN 240 VOLTS WILL DAMAGE EQUIPMENT. FOLLOW STANDARD PROCEDURES FOR REDUCING THE VOLTAGE.

A. Direct Connect Method

m WARNING

This WARNING applies to the use of the Direct Connect Cables and the Transmitter.To avoid potential shock, or electrically damaging the Transmitter, when setting up the Transmitter to locate using the Direct Connect method, follow these basic steps;• ALWAYS plug the Direct Connect Cable into the Transmitter Output Jack [T-6] BEFORE

connecting the leads to the cable/pipe to be located and the ground rod. – Connect the red lead to the cable/pipe. – Connect the black lead to ground rod.A POTENTIAL FOR ELECTRICAL SHOCK, AND/OR TRANSMITTER ELECTRICAL DAMAGE, EXISTS WHEN USING THE DIRECT CONNECT CABLE ON CABLES ENERGIZED WITH ELECTRICAL POWER IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED. USE APPROPRIATE SAFETY PROCEDURES.CHECK VOLTAGE BEFORE CONNECTING TRANSMITTER. VOLTAGE HIGHER THAN 240 VOLTS WILL DAMAGE EQUIPMENT. FOLLOW STANDARD PROCEDURES FOR REDUCING THE VOLTAGE.

PlugthedirectconnectcableintotheOutput Jack[T-6]ofthetransmitter.Connecttheblackcliptothegroundrod.Placethegroundrodintheearthperpendiculartothesuspectedcable/pipepath.Ifnecessary,extendtheblackleadwiththeGroundExtensionCable(#9043availableseparately).

Note: In the ohms mode, the transmitter can detect voltage as well as ohms. If a low voltage is detected, the display will alternate between displaying ohms and volts. When displaying ohms, the flag over the Ω symbol will be visible. When displaying volts, the flag over the ‘V' will be visible. When the voltage magnitude is sufficient to impair the accuracy of the ohms measurement, only voltage will be displayed. If the voltage is AC, a sine wave will be visible on the display [T-4]. If a high AC voltage is detected, a rapid beeping tone will be heard.

B. Dyna-Coupler Method

m WARNING

This WARNING applies to the following 3M Dyna-Couplers;• 3" (75 mm) - Part number 3001• 4.5" (114 mm) - Part number 4001• 6" (150 mm) - Part number 1196• All accessory kits containing any of the listed Dyna-Couplers - Part numbers 3019, 4519,

1196/CA potential for electrical shock exists when using the Dyna-Coupler on cables energized with electrical power. Use appropriate safety procedures.DO NOT USE ON CABLES CARRYING IN EXCESS OF 600 VOLTS RMS.

Use a ground extension cable, or wire, and ground rod set-up between a target pipe/cable and a gas meter valve/box, or cable/electrical meter box. This will isolate the locate signal to the target pipe/cable section below the meter/box, between the grounding points. This provides a good return path for the tracing signal. Insulating coupling above a gas meter valve on a pipe will isolate the returning signal from ground and may make locating more difficult.

1. ConnecttheDyna-CouplertothetransmitterOutput Jack[T-6]usingthecouplercable(9011).

2. ClamptheDyna-Coupleraroundthecableorpipe,belowanybonds,justbeforeitenterstheearth.The jaws of the coupler must fully close.

3. PressTrace [T-3]toturnonthetransmitter.Pressagaintoselect8kHz,33kHzor200kHz.

Note: When using a Dyna-Coupler, always select high or maximum output power level by pressing the Output Level [T-5] key on the transmitter.

andmetalpipes),butwouldrequireincreasedsweepdistanceseparationbetweenthetransmitterandreceiver.

Note: If nothing is plugged into the Output Jack [T-6] of the transmitter, the transmitter will automatically turn on the internal antennae, and the last frequency used (8 kHz (12 Watt transmitter only), 33 kHz or 200 kHz) will broadcast in induction mode.

The induction frequency can be changed by pressing the Frequency button on the transmitter. For best results, the receiver should be at least 25 feet (7.6 m) away from the transmitter to begin tracing the target path and have the gain set between 78-84% when starting the sweep. This is used to establish a baseline gain threshold prior to starting a sweep. When crossing a target pipe or cable, the bar graph will close and the signal strength and audio response will increase. Attempting to trace the target close to the transmitter may lead to false indications due to the receiver detecting the large magnetic field radiating from the transmitter.
