7 Resistance Measurement
7.1 Operating modes
The unit can perform resistance on all types of objects, but has been specially designed to
measure resistance on highly inductive objects (as for example transformer’s windings,
generators windings, etc).
During resistance measurement the device can be used in two operating modes: the “classic
mode” and the “automated mode”.
Automated mode is used for measuring resistance on power transformer, as the unit is equipped
with an internal relay matrix that perform the test in all phases of a three phase transformer
without any reconnection.
Classic mode is used for measuring resistances or any test object different from a transformer.
Selection on the measuring mode is
done in the Setup screen, accessible
over:
Select the Test Mode “Automated” or
”Classic”
7.2 Automated mode
7.2.1 General
On automated mode, the unit will perform all necessary steps to measure all resistances on a
transformer automatically.
