Instructions

1. Unplug all appliances or equipment on the circuit being tested.
2. Plug the GT-10 into any standard 120 V AC receptacle (NEMA 5-15R).
3. Compare the illuminated lamps on the GT-10 to the code key locatedon the product or in the table above.

Note: If the LEDs indicate anything other than "Correct Wiring", have the wiring verified by a qualified electrician.

Note: The GT-10 is not a comprehensive diagnostic instrument. The GT-10 is a simple instrument designed to detect nearly all, probable and common, improper wiring conditions. It will not detect a combination of defects. It will not indicate the quality of ground or reversal of grounded and grounding conductors. It will not detect two hot wires in a circuit. Circuit capacitance may indicate continuity in an open circuit. Failure to unplug appliances or equipment on the circuit being tested can cause erroneous readings.
