6. Initial calibration

Set up the demo multimeter vertically.

Do not connect measuring leads to begin
with.

Set the toggle switch 1 to

Set the power switch to .
The needle will point to the zero point of the scale
on the left. If it does not, the amount of charge of
the battery should be checked.
7.1 To switch on:

7.2 Checking battery charge:




If the battery is sufficiently charged, the needle
will point to the following range indication,
need to be replaced immediately.

7.3 Zero point calibration:





7.4 Zero point calibration for centre zero
For measurements of DC current and voltage, the
zero point of the scale can be moved to the centre
of the dial. For this purpose the scales are la-
belled with red numbers..

7. Operation
Set the power switch to .
Turn on the demo-multimeter.
Disconnect all measuring leads.
Set the toggle switch 2 to
Set the rotary switch to
. If this is not the case, the battery will
Turn on the demo-multimeter.
Turn the rotary switch to 600 V.
Connect the common/ground socket and the
voltage measurement socket together by
means of a short connecting lead.
Turn the zero-point trimmer screw to adjust
the zero point as needed.
