4）Plug the relay into one of the three sockets

5）Press the "Test" button

6）The tester will automatically detect the pin position of the unknown relay. When the relay is not a universal relay on the market or is damaged, the tester will turn on a red LED light.

7）When the foot position is set correctly, the tester will open and close 10 times to detect the release time of the action. When the detection time is too long, the tester wil light up the red LED light.

8）When the tester has detected the action release time 10 times, start to detect the consistency of the relay. When the test is OK, turn on the green light, and if the test is not OK, turn on the red light.
