2-Pin Lemo Polarity Tester
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 Media Blackout created the 2-pin Lemo Polarity Tester.
To use the tester, plug the source-side of your 2-pin Lemo cable into any DC power source from 6-36V, and plug the device-side into the tester. The tester will show you if pin-1 is ground (GND) or positive (+VDC) by flashing one of two red LEDs. The tester also features a micro USB port for firmware updates.
