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.

(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).

Safety shutdown
At DUT differential current of > 10 mA,
shutdown time: < 500 ms,
can also be set to > 30 mA
in the event of probe current (electronic
fuse) during:
– Leakage current measurement:
> 30 mA~/< 500 ms*
– Protective conductor resistance
measurement:
> 250 mA~/< 1 ms
in case of continuous current I > 16.5 A
