ON:
Measurement using voltage transformers.
When measuring via voltage transformers, the
device must know the voltage transformation
ratio. For this purpose, the primary and sec-
ondary voltages must be specified in the fields
"PT PRIMARY" and "PT SECONDARY".
When changing from direct measurement to
measurement using voltage transformers, the
device accepts the last set reference measur-
ing voltage as the secondary voltage and as
the primary voltage.
•
Measurement directly on the low-voltage sys-
tem.
When changing from measurement using
voltage transformers to direct measurement,
the device accepts the last set secondary volt-
age as the reference measuring voltage.
