Resistance Measurement - VOLTCRAFT VC-20 Notice D'emploi

- Now connect the two test prods with the object to be measured
(signal generator, circuit etc.).
- The duty-cycle is indicated on the display.
d) Resistance measurement
Make sure that all the circuit parts, circuits and
components to be measured as well as other
objects of measurement are disconnected from the
voltage.
Proceed as follows to measure the resistance:
- Turn the DMM on at the rotary
switch (1) and select the measur-
ing range „ " .
- Check the measuring leads for
continuity by connecting both
test prods to one another. After
that the resistance value must be
approx. 0.5 Ohm.
- Now connect
prods to the object to be mea-
sured. As long as the object to be
measured is not high-resistive or interrupted, the measured value
will be indicated on the display (4).
- As soon as „O.L" (overflow) appears on the display, you have
exceeded the measuring range or the measuring circuit has been
interrupted.
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 may falsify the measured
result.
