Mathematical Functions
The resistance value depends on the used cable length.
The longer the cable, the higher the resistance value. If the
resistance value is entered via soft menu key WIRE RES.,
the wire voltage drop will be deducted automatically and
the power at the load will be measured (please refer to ex-
ample fig. 6.10).
The wire resistance value (WIRE RES.) can only be set via inst-
rument front panel. The wire resistance value can not be set via
remote command.
