One of the biggest causes of damage to equipment on set is using a 2-pin Lemo cable that is not wired for the device it's plugged into. That's why Rencher Industries created the Polarity Tester for 2-pin Lemo Cables.
To use the tester, plug the source-side of your 2-pin Lemo cable into any DC power source from 8-36V, and plug the device-side into the tester. The tester will show you if pin-1 is ground (GND) or positive (+VDC) by glowing one of two red colors: Green from Pin-1 GND, and Red for Pin-1 +VDC
All Rencher Industries products that use 3D printed parts carry a 5-year warranty on the printed material. If your 3D printed part warps, cracks, or fails for any reason, we will replace the defective printed part at no cost.
United StatesWorks great and gives me peace of mind before plugging in any 2pin devices.
