MD 9231 Industrial TRMS AC/DC Current Clamp Meter Operation
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
Using Resistance, Continuity or Diode 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.
Capacitance function
Inputs are made through the test lead terminals COM/+. Last selection will be saved as power up default for
repeat measurement convenience. Press SELECT button momentarily to select the subject functions in
sequence.
