Display range
Voltage : 5 V to 1,000 V; separate warning displayed when over-
range
Zero-suppression processing forces volta
ge RMS values
of less than 5 V to be displayed as 0 V.
If the voltage RMS value is 0 V, a harmonic voltage of 0 is
used for all orders. (PW336
0-21 only)
Current : 0.4% to 130% of range
Separate warning displayed when over-range or over-
peak.
Zero-suppression processing forces current R
MS values
of less than
0.4% to be displayed as 0 A.
If the harmonic current is 0 A, a harmonic current of 0 is
used for all orders. (PW336
0-21 only)
Power : 0% to 130% of range (zer
o-suppression is triggered when
the voltage RMS value or current RMS value is 0)
If the voltage RMS value or current RMS value is 0, a har-
monic active power and harmonic reactive power of 0 are
used for all orders. (PW3360-21 only)
