VOLTCRAFT Multi-DMM MT-52 Bedienungsanleitung Seite 58

Proceed as follows to measure "V-DC" di-
rect voltages:
• Turn the DMM on and select measuring
function "V=".
• Plug the red measuring lead into the V
measuring socket (9) and the black measur-
ing 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 indicates 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 voltage 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.
Use the "Hz%" button (11) to switch the display to frequency (Hz) and pulse length
(%). Each press switches the function. Autorange is deactivated. This enables monito-
ring of possible ripple voltage (superimposed alternate voltage). In case of pure direct
voltage, the frequency and % displays are "zero". Without a measured signal, phan-
tom values may be displayed. They disappear when a direct voltage is measured.
