Measuring; A) Voltage Measuring „V - VOLTCRAFT VC-666 Bedienungsanleitung

Measuring

Do not exceed the maximum permitted input values. Do not
contact circuits or parts of circuits if there could be voltages
higher than 25 V ACrms or 35 V DC present within them. Mortal
danger!
Before measuring, check the connected measuring cable for
damage such as, for example, cuts, cracks or squeezing. Defec-
tive measuring cables must no longer be used. Mortal danger!
a) Voltage measuring „V"
Proceed as follows to measure DC voltages (V
- Turn the DMM on on the rotary switch and select the right measuring range for
your voltage „V
- Now connect the two test prods to the object
to be measured (battery, circuit etc.).
The red measuring tip indicates the positive
pole, the black measuring tip the negative
pole.
- The polarity of the respective measuring value is indicated on the together with
the current measuring value.
As soon as a minus „-" appears for the direct voltage in front of the
measuring value, the measured voltage is negative (or the measu-
ring tips have been mixed up).
- After you finish testing, always switch the measuring device off. Turn the rotary
switch to "OFF".
