Resistance Measurement - VOLTCRAFT CT-3 Bedienungsanleitung

c) Resistance measurement
Make sure that all the circuit parts, switches and components and
other objects to be measured are disconnected from the voltage
at all times.
Proceed as follows to measure resistances:
- Turn the multimeter on using the rotary
and select the measuring range „Ω" .
Insert the measuring lines into the
measuring sockets.
- Check the measuring leads for conti-
nuity by connecting the measuring
prods with one another. After that the
resistance value must be approximate-
ly 0 Ohm.
- Now connect the measuring prods to
the object to be measured. As long as
the object to be measured is not high-resistance or interrupted, the measured
value will be indicated on the display (2).
- As soon as „O.L" (overflow) appears on the display, you have exceeded the mea-
suring range or the measuring circuit has been interrupted.
If you carry out a resistance measurement, make sure that the measu-
ring points which you contact with the test prods are free from dirt, oil,
solderable lacquer or the like. An incorrect measurement may result
under such circumstances.
