A) Voltage Measuring "V - VOLTCRAFT VC135 Bedienungsanleitung

As soon as "1" (towards the left side of the display) appears on the display, you have
exceeded the measuring range. Select the next higher measuring range
The voltage range „V/DC" has an input resistance of >10 MΩ, the V/AC range of
>4.5 MΩ.
With the digital multimeter, the automatic range selection (auto range) is active in all
measuring functions (except for currency measuring ranges). This function sets the
right measuring range automatically.

a) Voltage measuring "V"

Before measuring voltages, always make sure that the measuring instrument
is not set to a measuring range for current.
Proceed as follows to measure DC voltages "DC" (V
1. Turn the DMM on and select the measuring range "V
values on the rotary switch (5) indicates the maximum measurement value of that selection.
2. Insert the red measuring lead into the V socket (8) and the black measuring lead into the
COM socket (9).
3. Now connect the two measuring prods to the object to be measured (battery, switch etc.).
4. The red measuring tip indicates the positive pole, the black measuring tip the negative pole.
5. The polarity of the respective measuring value is indicated on the together with the current
measuring value. The unit of the measurement is V.
As soon as a minus "-" appears for the direct voltage in front of the measuring value,
the measured voltage is negative (or the measuring tips have been mixed up).
6. After measuring, remove the measuring leads from the measuring object and turn the DMM
off. Turn the rotary switch to the position "OFF" .
Proceed as follows to measure AC voltages (V~):
1. Put the DMM into operation as described in the section "Measuring of direct voltage" and
select the measuring range "V ".
2. Now connect the two measuring leads to the object to be measured (generator, switch etc.).
3. The measuring value is indicated on the display. The unit of the measurement is V.
4. After measuring, remove the measuring leads from the measuring object and turn the DMM
off. Turn the rotary switch to the position "OFF".
