SDM3055 Digital Multimeter 47
the reading exceeds the threshold,
“
open
”
will be displayed.
5. Evaluate the results of measurement
Reverse the probes and measure the forward voltage drop on the diode
again. Evaluate the diode according to the following rules:

If the Multimeter displays
“open” when in reverse bias model, it
indicates that the diode is normal.

If the Multimeter shows voltage about 0V and the instrument beeps
persistently when in forward and reverse bias model, it indicates that the
diode is short.

If the Multimeter shows
“open” when in forward and reverse model, it
indicates that the diode is open.
6. Make math operation (advanced)
You can perform math operation (Statistics, Limit) on every measurement
reading. For details, please refer to “Math Operations”.
7. Display the graph (advanced)
You can analyze the measurement data by using
“Bar Meter”, “Trend Char”
or
“Histogram display”. For details, please refer to “
Display Mode
”.
Note:
Before testing diode, please cut off the power and discharge all the
high-voltage containers to avoid damages to the Multimeter.
