Threshold level
The threshold level indicates the field strength
at which the instrument’s audible signal is first
emitted. The threshold level can be selected by
the user in accordance with the table. The stan-
dard settings when the instrument is switched
on are 10 V/m and 0.2
µ
T. If you want to select
a different value, hold one of the keys depres-
sed while starting up the instrument. Then se-
lect the desired limit using the appropriate key.
To exit the setting procedure, press both keys at
the same time. The selected threshold level is
stored as long as the instrument is switched on.

Changing the batteries
When the battery symbol is displayed to the left
of the measurement reading, the batteries should
be replaced immediately. Unscrew the cover on
the rear of the instrument, remove the old batte-
ries and install new ones (2 x 1.5 V LR6).

Report forms
On the following pages you will find report form
templates for measuring electric and magnetic
fields. Copy the templates, fill them out and then
file them in a folder. You can then go back and
make comparisons with previous measurements.
Section 4 gives examples of how to carry out
measurements, while subsection 4.3 details how
to fill out the report forms.
