Measurement Operation (9)
Note
l In a circuit, a good diode should still produce a
forward voltage drop reading of 0.5V to 0.8V;
however, the reverse voltage drop reading can vary
depending on the resistance of other pathways
between the probe tips.
l Connect the test leads to the proper terminals as
said above to avoid error display.
l The LCD will display
indicating open-circuit for
wrong connection.
l The unit of diode is Volt (V), displaying the positive-
connection voltage-drop value.
l When diode testing has been completed, disconnect
the connection between the testing leads and the
circuit under test.
F. DC or AC Current Measurement (see figure 11)
Warning
Never attempt an in-circuit current measurement
where the open-circuit voltage between the circuit
and ground is greater than 250V.
If the fuse burns out during measurement, the Meter
may be damaged or the operator himself may be
hurt. Use proper terminals, function, and range for
the measurement. When the testing leads are
connected to the current terminals, do not parallel
them across any circuit.
