shorted diode (defective). An OL indicates an open diode (defective). Reverse the test
leads connections (reverse biased) across the diode. The digital display shows OL if
the diode is good. Any other readings indicate the diode is resistive or shorted

protection circuitry of the meter when measuring low capacitance in the order of Pico
Farad (pF).
CAUTION
Discharge capacitors before making any measurement. Large value capacitors should
be discharged through an appropriate resistance load
