For time relay testing,Relay Tester UA=110V and UB=－110V can be set in the software,Relay Tester and connect the UA and UB of the tester to the two ends of the voltage coil of the relay. At this time,Relay Tester the DC voltage output by the tester is 220V. The opening amount of the tester should be connected to the delay contact of the relay.

Select the "Manual" test method. After a certain period of time,Relay Tester the action time can be tested. If you want to test the operating voltage of the relay,Relay Tester you can set a certain voltage in UA and UB as a variable,Relay Tester and change the size of UAB to protection action from a small step to a large step. When doing this test,Relay Tester the input of the tester should be connected to the instantaneous contact of the relay.
