High resistance ohmmeter
WebIf such an ohmmeter were used to test a diode, it would indicate a very high resistance (many mega-ohms) even if connected to the diode in the “correct” (forward-biased) direction. (Figure below) Ohmmeter equipped with a low test voltage, too low to forward bias diodes, does not see diodes. WebFor resistance higher than 1.9999 Tera ohms, the conductance range can be used to measure conductance down to 0.01 pS (100 T ohms ). The meter has a conductance …
