d) Resistance Measuring
Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
- Turn the DMM on and select measuring function "Ω".
- Plug the red measuring line into the Ω measuring jack (9)
and the black measuring line into the COM measuring jack
(8) .
- Check the measuring lines for continuity by connecting
both measuring prods with one another. The resistance
value must be approximately 0 - 0.5 Ohm (inherent resi-
stance of the measuring lines).
- Now connect the measuring prods to the object to be
measured. As long as the object to be measured is not
high-Ohm or interrupted, the measured value will be indi-
cated on the display. Wait until the displayed value has sta-
bilised. With resistances of >1 MOhm, this may take a few
seconds.
- If "OL" (overload) appears on the display, you have excee-
ded the measuring range or the measuring circuit has
been broken.
- After measuring, remove the measuring lines from the
measured object and turn the DMM off.
If you carry out a resistance measurement, make sure that the measuring points which you
contact with the test prods are free from dirt, oil, solderable lacquer or the like. Such circum-
stances can falsify the measured result.
