Test Different Relay Pins

Relay Tester is able to accept 3 different specifications of relay pins. Relay switching with 4 or 5 pins are usable on the tester.


Red/Green Light

If the relay is abnormal, the light Red LED will flash, and if it is normal, then Green LED will flash. SO easy and quick.
