Ac ("Mv ") / ("Mv ") Voltage Mode; Loz Voltage Mode - VOLTCRAFT VC252 Operating Instructions Manual

12.4 AC ("mV
1. Switch on the DMM and select "mV
Æ
"DC" and "mV" will appear on the display.
2. Press the SEL button on the control dial to switch to "AC" mode.
Æ
"AC", "TRMS" and "mV" will appear on the display.
3. Plug the red lead into the V terminal and the black lead into the COM terminal.
4. Connect the two measuring probes in parallel to the object that you want to
measure (e.g. generator or circuit).
Æ
The measurement will appear on the display.
5. After taking a measurement, remove the leads from the measured object and
switch off the DMM.
The "V/AC" range has an input resistance of ≥10 MΩ. This means that
there is almost no load on the circuit.

12.5 LoZ voltage mode

LoZ mode allows you to measure DC and AC voltages with a low impedance (ap-
prox. 400 kΩ). In this mode, the multimeter lowers the internal resistance to prevent
'phantom' voltage readings. As a result, the circuit is more heavily loaded than in the
standard measuring mode.
1. To enable LoZ mode, press the LoZ button when taking a voltage measurement.
The impedance will be reduced until you release the button.
2. "LoZ" will appear on the display.
LoZ mode can only be used for circuits with a voltage of up to 250 V for
a maximum of 3 seconds. This function is not available in mV mode.
After using LoZ mode, leave the multimeter for 1 minute before using
it again.
