Continuity Testing
WARNING
To avoid damaging the multimeter or
the object being measured, ALWAYS
disconnect the circuit power and
discharge all high-voltage capacitors
before testing for continuity.
1. Insert the black test lead into the COM
terminal, and the red test lead in to the
terminal.
2. Turn the rotary dial to .
3. Test the test leads before measurement
by connecting the metal ends of the leads
together. The multimeter will beep to
indicate that the test leads are working
properly. [
Figure 2.1 ]
4. Connect the test leads to the object being
measured. Hold them in place until the
multimeter beeps.
Diode Testing
WARNING
To avoid damaging the multimeter or
the object being measured, ALWAYS
disconnect the circuit power and
discharge all high-voltage capacitors
before testing diodes.
This test sends a current of 2.1V through
a diode or a semiconductor junction, then
measures the voltage drop across the junction.
1. Insert the black test lead into the COM
terminal, and the red test lead in to the
terminal.
2. Turn the rotary dial to .
3. Connect the test leads to the object being
measured. Hold the leads in place until the
readings on the display stabilize.
Note:
• The LCD will read “ ” if the test leads
are incorrectly connected or if the diode
is open.
• The average value for a PN silicon
junction is 500~800mV (0.5~0.8V).
