MD 9250 Clamp Meter Series Operation
11
Note
When using Diode test function, normal forward voltage drop (forward biased) for a
good silicon diode is between 0.400V to 0.900V. A reading higher than that indicates a
leaky diode (defective). A zero reading indicates a 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 (defective).
CAUTION
1. Using Resistance, Continuity, Diode or Capacitance function in a live circuit will
produce false results and may damage the meter. In many cases the suspected
component(s) must be disconnected from the circuit to obtain an accurate measurement
reading.
2. When using Capacitance function, discharge capacitor(s) before making any
measurements. Large value capacitors should be discharged through an appropriate
resistance load
