GREENLEE GT-16 (01) PDF Document

The GREENLEE GT-16 voltage detector is designed to check for the presence of AC voltage. It signals the user through an intermittent tone and a flashing LED. The LED also flashes periodically to confirm the current condition of the battery.

Warning: Read the instruction manual.

Risk of electric shock.

Double insulation.

Do not assume that the absence of a voltage indication means the circuit is de-energized.

Follow the 3-point safety method as described in the operation procedures.

Do not use the unit if it is wet or damaged.

Do not apply more than the rated voltage between the detector tip and earth ground.

Do not operate the tool with the case open.

Using this unit near equipment that generates electromagnetic interference can result in unstable or inaccurate readings.

The tester will not detect voltage in the following situations:

Through metal conduit.

On armored or shielded cable.

On sheathed nonmetallic cable that is saturated with water.

At a distance, such as through walls.

Step 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 must be replaced.

Step 2: Test the unit on a known live circuit before each use to ensure it functions as expected. If it does not, replace the battery.

Step 3: Place the tip on or near the circuit or unit to be tested. A tone and flashing LED indicate the presence of voltage (5 VAC to 1000 VAC).

Step 4: After use, test the unit again on a known live circuit to verify proper operation.

To find a break in a hot conductor, trace the wire with the unit until the signal stops.

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

Note: For round cords which may have twisted conductors, check for hot conductors by sliding the unit along the length of the cord.

Use maximum sensitivity when you need to detect low voltages. Reduce the sensitivity when you are trying to find breaks in wires or identify hot and neutral conductors.

Note: This tool is for indoor use only.

Measurement Category IV refers to the primary supply level. This includes overhead lines and other cable systems. Specific examples include cables, meters, transformers, and other exterior equipment owned by a power utility.

Step 1: Disconnect the unit from any circuit.

Step 2: Rotate the outer battery cap clockwise and remove it.

Step 3: Rotate the metal inner cap and remove it.

Step 4: Replace the battery with a new 1.5 volt AAA battery, ensuring the polarity is correct.

Step 5: Replace and secure the metal inner cap.

Step 6: Replace and secure the outer battery cap.

Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents to clean the unit.
