After taking a measurement, remove the leads from the measured object and
switch off the DMM.
When taking a resistance measurement, make sure that the points that
come into contact with the measuring prods are free from dirt, oil, solder
and other impurities. These substances may distort the measurement.
9.7 Conducting a continuity test
Make sure that all objects that you wish to measure (including cir-
cuit components, circuits and component parts) are disconnected
and discharged.
Switch on the DMM and select the
The continuity test symbol and the Ω sym-
bol will appear on the display. Press the but-
ton again to switch to the next measuring
mode.
Plug the red lead into the V terminal (K) and
the black lead into the COM terminal (I).
An approximate value of <50 Ohm is rec-
ognized and you will hear a beep. The
continuity test measures resistances of up
to 400 Ohm.
"OL" (overload) indicates that the measur-
ing range has been exceeded or that the
circuit is broken.
After taking a measurement, remove the
leads from the measured object and switch
off the DMM.
