10. Voltage measurements
The demo-multimeter may NOT be
used for direct measurements on a
building's electrical wiring installation
or directly at the source of the mains
voltage feed to the junction box. See
page 2 of "Measurement categories"
as specified in DIN EN 61010-1.
The nominal voltage of the voltage
source may not exceed 600 V.


If measurements are made when the magni-
tude of the variable is unknown, always select
a large measuring range before shifting down
to lower ones.

Connect the common/ground lead first and
only then the signal lead.
10.1 DC voltages up to 600 V:

Set the toggle switch 2 to

Alternatively, if measurements are to be
made with the zero point in the centre, then
set the toggle switch 1 to

Select the required measuring range to a
range measured in V.

For measurements of voltage up to 100 mV,
set the rotary switch to the range 0.1
mA/100 mV.
10.2 AC voltages up to 600 V:

Set the toggle switch 2 to

Select the required measuring range to a
range measured in V.

For measurements of voltage up to 100 mV,
set the rotary switch to the range 0.1
mA/100 mV.

source may not exceed 600 V.

The multimeter is to be connected
in series with the load on the side
where the voltage with respect to
ground is lowest!

Turn off the circuit before meter is
connected into it.
