11.4 Resistance measurement
Make sure that all the circuit parts, switches and components and other objects of measurement are
disconnected from the voltage and discharged�
1� Turn the DMM on and select measuring function "Ω".
2� Plug the red measuring line into the Ω measuring jack (9) and the
black measuring line into the COM measuring jack (8) �
3� Check the measuring lines for continuity by connecting both measur-
ing prods with one another� The resistance value must be approxi-
mately 0 - 0�5 Ohm (inherent resistance of the measuring lines)�
4� 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 indicated on the display� Wait until the
displayed value has stabilised� With resistances of >1 MOhm, this
may take a few seconds�
5� If "OL" (overload) appears on the display, you have exceeded the
measuring range or the measuring circuit has been broken�
6� After measuring, remove the measuring lines from the measured
object and turn the DMM off�
Note:
– 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 circumstances can falsify the measured
result�
