Making Measurements
4. Connect the probe to the semiconductor device you
0 to check and note the meter reading.
5. Reverse the probes and note the second reading. If
the first reading shows some value and second is
overrange, the device is good. If both are overrange, the
device is open. If the reading are both very small or zero,
the device is shorted.
Note: The values indicated on the display during the
diode check operation shows the actual forward voltage
(max. 2V). If the value is around 0.400 the device is
germanium type: if it is around 0.600 the device is
silicon type. An LED will make the meter display a value
of about 1.800.
