Resistance Measuring; B) Resistance Measurement - VOLTCRAFT VC-666 Bedienungsanleitung

Proceed as follows to measure AC voltages (V
- Turn the DMM on on the rotary switch and select the right measuring range for
your voltage „V
- Now connect the two measuring prods to
the object to be measured (generator, swit-
ching etc.).
- The measuring value is indicated on the
display
The voltage range „V DC/AC" shows an input resistance of >1 MOhm.
- After you finish testing, always switch the measuring device off. Turn the rotary
switch to „OFF".
b) Resistance measuring
Make sure that all the circuit parts, switches and components
and other objects of measurement are disconnected from the
voltage at all times.
Proceed as follows to measure the resistance:
- Turn the DMM on on the rotary switch and select the right measuring range for
your voltage „Ω".
- Check the measuring leads for continuity by connecting both measuring prods to
one another. After that the resistance value must be approximately 0.5 Ohm.
- Now connect the measuring prods to the object to be
measured. As long as the object to be measured is not
high-resistive or interrupted, the measured value will
be indicated on the display.
- As soon as „1" (= overflow) appears on the display, you have exceeded the mea-
suring range or the measuring circuit has been interrupted. Switch to the next
higher measuring range.
- After you finish testing, always switch the measuring device off. Turn the rotary
switch to „OFF".
