Displays the RMS voltage or current of the
signal connected to the input
CT polarity Fwd/Rev Indicates the polarity of a CT connected
between the current output (primary) and
auxiliary current input (secondary)
CT ratio 5A 5000:5A Displays the ratio of a 5A CT connected
between the current output (primary) and
auxiliary current input (secondary)
CT ratio 1A 5000:1A Displays the ratio of a 1A CT connected
between the current output (primary) and
auxiliary current input (secondary)
Phase -179.9° to +180.0° Displays the phase angle between the
output current and the voltage or current
connected to the auxiliary input. Only active
if the output current is <10% of the selected
metering range and the auxiliary input is
>0.5A or 20V.
Hz 45.00-99.99Hz Displays the frequency of the voltage or
current of the signal connected to the input.
Only active if the auxiliary input is >0.5A or
20V.
