8. Current measurements up to 3 A
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 current
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.

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 terminal at the lower potential to
the common/ground socket.
Connect the common/ground lead first and
only then the signal lead.
8.1 DC currents up to 3 A:
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 current measuring range
to a range measured in mA or A.
8.2 AC currents up to 3 A:
Set the toggle switch 2 to
Select the required current measuring range
to a range measured in mA or A.
