Place of use Indoors, except within
specified ambient condi-
tions
In order to avoid deviation due to excessive
temperature fluctuation, e.g. after transport
in low outdoor temperatures and subse-
quent operation in a warm indoor environ-
ment, it’s advisable to wait until the test
instrument has acclimatized before starting
any measurements.
If the test instrument is colder than the ambi-
ent 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, in turn, affect the mea-
suring circuit and measuring accuracy.

Electrical Safety
Protection
category 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 terminal,
USB, finger contact, test
probe(s) test socket)
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).
