measured values
The function freezes a measured value when a signal
arrives at the
STOP INPUT or when the current is
interrupted.

The frozen values disappears when you start
a new current generation operation or press
RESET
.
7.11 Measuring phase
angle and polarity
INGVAR can display the phase angle between the cur-
rent from INGVAR (A-METER) and:
A]
the current (I2) passing through INGVAR’s
second ammeter "A-METER 2"
or
B]
the voltage (V) at the voltmeter input.
