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
"DC" and "mV" will appear on the display.
Æ
2. Press the SEL button on the control dial to switch to "AC" mode.
"AC", "TRMS" and "mV" will appear on the display.
Æ
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).
The measurement will appear on the display.
Æ
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.
