F) Dc Voltage Mode ("Mv "); G) Loz Voltage Mode - VOLTCRAFT VC281 TRMS Bedienungsanleitung

f) DC voltage mode ("mV ")

Proceed as follows to measure direct voltages "mV/DC":
- Switch the DMM on and select the "mV
mode. "DC" and "mV" will appear on the display.
- Insert the red lead into the V socket (G) and the black lead into
the COM socket (H).
- Connect the two measuring probes in parallel to the object that
you want to measure (e.g. battery or circuit).
- The measurement will appear on the display.
- After taking a measurement, remove the leads from the meas-
ured object and switch the DMM off.
The "mV/DC" voltage measurement range has an
resistance of ≤1000 MΩ. This (almost entirely) pre-
vents a load on the circuit.

g) LoZ voltage mode

LoZ mode allows you to measure DC and AC voltages with a low impedance (approx. 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.
In order to use LoZ measurement mode, press the "Low imp.400 kΩ" button (J) during voltage measurement. The
measured impedance is reduced for as long as the button is pressed.
"LoZ" (B17) will appear on the display.
LoZ measurement mode may only be used up to a maximum voltage of 250 V. The duration of the LoZ
measurement must be limited to a maximum of 3 s. This mode is not available in the mV measurement
range.
After using LoZ mode, leave the multimeter for 1 minute before using it again.
