Hi Vysakh The test voltage in case of DMM is less than 2.5 volt hence knee voltage is higher than 2.0volt cannot be displayed. This is the reason you cannot check Diac also with multimeter.

in diode selector mode the forward biased condition only showing low resistance (400-850R without any external supply) . It doesnt showing knee voltage . In reverse condition showing infinite reading (always 1) in the case of digital meter

Thank You, this was very helpful for a solar project that I am working on. Cheaper panels don’t come with the blocking diodes and I needed to know how to test the ones that I scrounged up, the write up jiggled my memories on how to drive my multimeter.
