Resistance Measurement - VOLTCRAFT VC-10 Bedienungsanleitung

c) Resistance measurement
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 at the rotary
switch (1) and select the measu-
ring range „ " .
• Check the measuring lines for
continuity by connecting both
measuring prods to one another.
After that the resistance value
must be approx. 0.5 ohm.
• Now connect
prods to the object to be measu-
red. As long as the object to be
measured is not high-resistive or
is interrupted,
value will be displayed on the display (4).
• As soon as „OL" (overload) appears on the display, you have
exceeded the measuring range or the measuring circuit has been
broken.
If you carry out a resistance measurement, make sure that
the measuring points which you contact with the measuring
prods are free from dirt, oil, solderable lacquer or similar.
Such circumstances can falsify the measured result.
