P3
– Green (normal) threshold for Magnitude @0.2 ppc (mV)
P4
– Yellow (warning) threshold for Magnitude @0.2 ppc (mV)
P5
– Red (alarm) threshold for Magnitude @0.2 ppc (mV)
List of status thresholds for trend:
P0
– Yellow (warning) threshold for trend (times per year). Recommended 3-5times/year.
P1
– Red (alarm) threshold for trend (times per year). Recommended 5-10times/year.

Rated Voltage:
Object under test rated voltage is used for calculation of partial discharge intensity. Set rated voltage line-
to-line in terms of kV.
Scroll setup parameters until
VOLtAGE

I-00001.0
will appear. Use
keys to set the rated current of the object under
test in A (usually full load or nominal current).
When done, press
Enter
.
Number of Power Cycles for Data Acquisition:
This setting determines the length of time the device will acquire data to get sufficient statistical PD
representation. The parameter is measured in terms of number of cycles of power frequency. 60 cycles is
recommended for rotating machines and 120 cycles for switchgear.
Scroll setup parameters until
SinCount
appears.
Press
Enter
.
Cnt-06
will appear. Use
keys to set the number of power cycles (of 60 or 50 Hz) for
the measurement.
When done, press
Enter
.
Alarm Relay Mode:
Alarm Relay can be set in one of three modes:
Disabled (
OFF
) – Relay will not close contacts in a case of alarm
