How To Measure Voltage Drop Across A Relay at Carole Boyle blog

How To Measure Voltage Drop Across A Relay. The reading on the dvm is the voltage drop across the contacts. Are you using a true rms meter as russs57 mentioned?. Voltmeter should be set to mv (millivolts), or on the lowest volt range. This can only be done by conducting a millivolt drop test across the line and load terminals of each pole with the contacts. Maximum allowable voltage drop for any relay or switch. Set the dvm to measure voltage. It might be best to measure all three ways to make sure that the measurements come up with the same voltage drop. At any moment, the voltage that you're reading between pin 30 and pin 87, and that between pin 87 and ground, have to add up to. Turn on the coil power supply to energize the coil and engage the contacts. Set the \$v_{max}\$ to 1 v and \$i_{max}\$ to 10 ma and try testing some switches or relays that haven't been switched for a while and see what voltage.
