About: Whirlwind TLT Power Cable Tester (True1)

The Whirlwind TLT (Tester Line-True1) is a dedicated test device for Neutrik Powercon True1 three wire power cords. Its battery powered continuity testers that conveniently verify the condition of power cables that are difficult to test without applying dangerous line voltage. Each of the three conductors is tested for continuity, shorts and incorrect connections.

Testing cables is as easy as plugging them in. The TLT has three green and one red LED that indicate correct wiring or any fault conditions. Operation is hands-free; there are no buttons to push or knobs to turn.

A properly wired line cord will show all three green LEDs illuminated. The earth LED light comes on before the Neutral and Line LEDs to confirm the Earth connection making first and breaking last.

The Whirlwind TLT is powered by a single 9 Volt battery located inside the unit. To install or replace the battery, remove the 6 case screws and connect the battery to the battery clip. Replace the bottom and close with the provided case screws. Do not use longer screws as they might puncture the battery. A battery test button is provided to confirm that the battery is capable of properly testing cables. The Earth LED illuminates when the Battery Test button is pushed and the battery is good.
