Power calculation
mode
S=f(P, Q) (using
reactive power),
Q=f(S, P) (using
non-active power)
S=f(P, Q) The method used for calculating reactive
and apparent powers (see “Power
Calculation Modes” below)

10,000,000 kWh
100,000,000 kWh
1,000,000,000 kWh 1,000,000,000 The value at which energy counters roll
over to zero
Energy LED pulse
rate, Wh/pulse
0.01-100.00 1.80 Wh/pulse
(one equivalent
disk revolution)
LED pulse constant - the amount of
accumulated energy (in secondary
readings) giving one pulse via “kWh” and
“kvarh” LEDs.
VDC alarm LED
threshold, % 1.0-100.0 85.0% The VDC threshold in percent of the VDC
nominal voltage. When the measured VDC
voltage drops below this threshold, the
“VDC LOW” alarm LED is lit up. A 5%
hysteresis is provided by default.
Volts Scale, V 10-828 V 828 V The maximum voltage scale allowed, in
secondary volts. See
Data Scales in
Appendix E.
Amps Scale, A 1.0-20.0 A 2.0/10.0 A (IEC)
4.0/20.0 A (ANSI) The maximum current scale allowed, in
secondary amps. See
Data Scales in
Appendix E.
