B) Voltage Measuring "V - VOLTCRAFT MT-52 Bedienungsanleitung

b) Voltage Measuring "V"

The voltage range "V AC/DC" shows an input resistance of >10 MOhm.
Proceed as follows to measure AC voltages "V-AC":
- Turn the DMM on and select measuring function "V~".
- Plug the red measuring lead into the V measuring socket
(9) and the black measuring lead into the COM measuring
socket (8).
- Now connect the two measuring prods to the object to be
measured (power outlet, switch etc.).
- The currently measured value is indicated on the display
- After measuring, remove the measuring lines from the
measured object and turn the DMM off.
Use the "Hz%" button (11) to switch the display to
frequency (Hz) and pulse length (%). Each press
switches the function. Autorange is deactivated.
The mV-AC measuring range can only be selec-
ted via manual measuring range selection
("RANGE" button).
Proceed as follows to measure "V-DC" direct voltages:
- Turn the DMM on and select measuring function "V=".
- Plug the red measuring lead into the V measuring socket
(9) and the black measuring lead into the COM measuring
socket (8).
- Now connect the two measuring prods to the object to be
measured (battery, switch etc.). The red measuring tip indi-
cates the positive pole, the black measuring tip the negative
pole.
- The polarity of the respective measured value is indicated
on the display together with the current measured value.
As soon as a minus "-" appears for the direct vol-
tage in front of the measured value, the measured
voltage is negative (or the measuring tips have
been mixed up).
- After measuring, remove the measuring lines from the
measured object and turn the DMM off.
