Place of use Indoors, except within specified ambient
conditions
In order to avoid deviation due to excessive temperature fluctua-
tion, e.g. after outdoor transport at low temperature and subse-
quent operation in a warm indoor environment, it’s advisable to
wait until the test instrument has acclimatized before starting any
measurements.
If the test instrument is colder than the ambient air, condensation
may occur at high humidity, i.e. condensate may accumulate on
components. This could result in the occurrence of parasitic
capacitances and resistances which affect the measuring circuit
and measuring accuracy.

Electrical Safety
Protection class I per EN 61140
Nominal voltage 230 V
Test voltage 2.3 kV AC 50 Hz or 3.3 kV DC
(mains circuit / test socket to mains PE ter-
minal, USB, finger contact,

Measuring category Designed for 300 V CAT II
(but reduced to 250 V CAT II through the
use of fuses for increased user safety. The
user-friendly fuses are replaceable and
replacements are easily obtainable).
