The accuracy specified shall apply for the use of the three-wire test cable and shall apply up to
100 M
for the use of the optional "Commander" test probe.
The accuracy specified shall apply up to 100 M
for a relative air humidity > 85 %.
If the installation tester gets wet, the results might be affected. In this case, it is recommended to let
the installation tester and its accessories dry for at least 24 hours.
The maximum error under operating conditions corresponds to the maximum error under reference
conditions
5 % of the measured value.
