GREENLEE GT13 Voltage Detector

Description

The Greenlee GT13 Voltage Detector is intended to check for the presence of AC voltage, signaling the user with an intermittent tone and flashing LED. The GT13 has a Self Test feature that continuously tests the integrity of the entire unit including the antenna. The GT13 also features low battery indication, an auto power off feature and a flashlight. This tool is protected by U.S. Patent No. 7,733,078 and Canadian Patent No. 2,607,922.

Important Safety Information

WARNING!

Read and understand this material before operating or servicing this equipment. Failure to understand how to safely operate this tool could result in an accident causing serious injury or death.

Electric shock hazard:

Wear appropriate personal protective equipment, including eye protection and other PPE as required by your employer. Contact with live circuits could result in severe injury or death.
Do not assume that no voltage indication means that the circuit is de-energized.
Follow the 3-point safety method as described in the “Operation”
Do not use the unit if it is wet or damaged.
Do not apply more than the rated voltage between the tip and earth ground.
Do not operate with the case open.
This tester will not detect voltage through metal conduit, on armored or shielded cable, on sheathed nonmetallic cable that is saturated with water, or at a distance such as through walls.
Using this unit near equipment that generates electromagnetic interference can result in unstable or inaccurate readings.

Failure to observe these warnings could result in severe injury or death.

CAUTION!

Electric shock hazard:

Do not attempt to repair this unit. It contains no user-serviceable parts.
Do not attempt to repair or reshape the antenna if it becomes bent or deformed. The unit must be replaced.
Do not expose the unit to extremes in temperature or high humidity. Refer to “Specifications.” Failure to observe these precautions may result in injury and can damage the unit.

Operation

The Greenlee GT13 is useful for identifying hot and neutral conductors, finding a break in a wire, and detecting the presence of AC voltage at outlets, switches, circuit breakers, fuses, and wires and cables, including ROMEX® nonmetallic building electrical wire.
Note: Round cords may have twisted conductors. Check for hot conductors by sliding the unit along the cord.
Note: The GT13 can be used to find a break in a wire:

To find a break in a hot conductor, trace the wire until the signal stops.
To find a break in a neutral conductor, connect a load between the hot and neutral. Trace the wire until the signal stops.

Wear appropriate personal protective equipment, including eye protection and other PPE as required by your employer.
Turn the unit on by pressing the ON/OFF button. The flashlight can be turned on by pressing the flashlight button. Note: The flashlight can only be turned on after the unit is powered on.
- The unit will turn off automatically if the self-test fails. Do not use the unit.
- The LED will remain on continuously if the batteries are low. Replace the batteries as soon as possible.
Test the unit on a known live circuit before each use.
- The LED will flash to indicate the presence of voltage (50 to 1000 VAC). The beeper will also sound.
- If the unit does not function as expected on a known live circuit, replace the batteries.
- If the unit still does not function as expected, call Greenlee for technical assistance at 800-435-0786.
Place the tip on or near the circuit or unit to be tested. The LED will flash to indicate the presence of voltage (50 to 1000 VAC). The beeper will also sound.
Test again on a known live circuit after use to verify proper operation.
