ON: Measurement using voltage transformers.
When measuring via voltage transformer, the device must
know the voltage transformation ratio. For this purpose,
the primary and secondary voltages must be specified in
the fields "PT PRIMARY" and "PT SECONDARY".
When changing from direct measurement to measure‐
ment using voltage transformers, the device accepts the
last set reference measuring voltage as the secondary volt‐
age and as the primary voltage.
OFF: Measurement directly on the low-voltage system.
When changing from measurement using voltage trans‐
formers to direct measurement, the device accepts the last
set secondary voltage as the reference measuring voltage.
