VOLTCRAFT VC185 TRMS Notice D'emploi page 42

Proceed as follows to measure DC voltages "DC" (V
• Turn the digital multimeter on and select the measuring range "V
with the rotary switch (5). "DC" is displayed in the LC display (4).
• Auto-mode is selected by default. In auto-mode the digital multimeter
determines the voltage measuring range automatically. To switch
off auto-mode and select the measuring range manually, press the
SELECT button (1) once. The "Auto" symbol disappears from the LC
display (4).
• Press the SELECT button (1) repeatedly to choose the measuring
range. The decimal point of the display shifts position between the
digits indicating the currently set measuring range. Choose the
appropriate measuring range for your measuring task. Observe that
the maximum input values (also see chapter 14.. Technical Data) must
not be exceeded during measuring.
• To re-engage the auto-mode, press and hold the SELECT button (1)
for about 2 seconds. The "Auto" symbol appears on the LC display (4).
The auto-mode is activated.
• Insert the red measuring lead into the V socket (8) and the black
measuring lead into the COM socket (9).
• Now connect the two measuring prods to the object to be measured
(battery, switch etc.) in parallel.
• The red measuring tip indicates the positive pole, the black measuring
tip the negative pole.
• The negative polarity sign of the measuring value is indicated on the
LC display (4) together with the present measuring value if the test
prods are connected in reverse. The unit of the present measurement
is shown in V.
• Press the HOLD button (12) in order to lock the measured value if
needed. The hold symbol
HOLD button (12) in order to release the locked value. The hold symbol
disappears from the LC-display (4).
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).
• After measuring, remove the measuring leads from the measuring object and turn the digital multimeter off. Turn
the rotary switch to the position "OFF" .
