The compacently G5SB relay purchased G5SB relay several batches of G5SB-1C-12VDC relay, with a multimeter to test the normally closed contact impedance under normal conditions is less than 1 ohm, after dithering, some relay placed tens of minutes cannot be restored to a low impedance, the impedance of some thousand ohms, and some resistance will fluctuate, is now unable to determine test method of relay problem is a problem in itself.
