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 the DMM on and select the
mode
.
2. Press the SEL/
switch to the mode. The continuity
test symbol and the "Ω" symbol will
appear on the display. Press the but-
ton again to switch to the next mode.
3. Insert the red test lead into the
measurement socket and the black
test lead into the COM measurement
socket.
If the measured resistance is
Æ
equal to or less than 10 Ω, the
multimeter will beep to indicate continuity. There is no further beeping from
>100 Ω. The continuity test measures resistances of up to 600 Ω.
"OL" (overload) indicates that the measurement range has been exceeded
Æ
or that the circuit is broken.
4. After taking a measurement, remove the leads from the measured object and
switch the DMM off.
