Diode drop measuring with multi meter .
Hi,
i am using power diodes 300 A/600V.
while i am checking the diodes with DMM(RISH MAX) in diode mode ...some diodes showing the 0.256V (anode to cathode)in DMM..but very fewer diodes showing 0.126V(anode to cathode)....
how to decide this voltage drop in DMM.
but i found faulty diodes form 0.126V group after I.R and HV Test and initial power on the power supply they showing short.
