Important Safety Information
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:
Contact with live circuits could result in severe
injury or death.
Electric shock hazard:
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” section (steps 2, 3, and 4).
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.

Operation
The Greenlee GT-16 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®.
Note: Round cords may have twisted conductors. Check for hot
conductors by sliding the unit along the cord.
Note: The GT-16 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.
1. Turn the unit on by rotating the sensitivity adjustment thumbwheel
away from the OFF position. Verify that the LED flashes periodically.
If the LED does not flash, the battery is not working and needs to be
replaced.
2. Test the unit on a known live circuit before each use.
If the unit does not function as expected on a known live circuit,
replace the battery.
If the unit still does not function as expected, call Greenlee for
technical assistance at 800-435-0786.
3. Place the tip on or near the circuit or unit to be tested. Tone and
flashing LED indicate the presence of voltage (5 VAC to 1000 VAC).
Use maximum sensitivity to detect low voltages.
Reduce sensitivity to find breaks in wires or to identify hot and
neutral conductors.
4. Test again on a known live circuit after use to verify proper
operation.
