12.10 Continuity test
Make sure that all objects that you wish to measure (including circuit
components, circuits and component parts) are disconnected and dis-
charged.
1. Switch on the DMM and select the desired
mode .
2. Press the
SEL
/
button 1x to switch to
continuity test mode.
Æ
The continuity test symbol and the “Ω”
symbol will appear on the display.
3. Press the button again to switch to the
next measuring mode.
4. Plug the red lead into the
Ω
terminal and
the black lead into the
COM
terminal.
5. Connect the measuring probes to the object that you want to measure.
Æ
If the measured resistance is equal to or less than 10 Ω, the multimeter will
beep to indicate continuity. The beeps stop when the resistance exceeds
100 Ω. The continuity test measures resistances of up to 400 Ohm.
Æ
“OL” (overload) indicates that the measuring range has been exceeded or
that the circuit is broken.
6. After taking a measurement, remove the leads from the measured object and
switch off the DMM.
