Function description
Frequency measurement
Measurement functions
Values (Range) Unit
0.00...40.00 xIn
Value
At the frequency f = f
±0.5% or ±0.002 × I
(at currents in the range of 0.01...4.00 × I
DFT: -50 dB at f = n × f
RMS: No suppression
Change
-
Residual current angle and demand value added
to Monitored data view. Recorded data added for
minimum and maximum values with timestamps.
Monitored data Min demand Io maximum value
range (RESCMSTA2.MinAmps.maxVal.f ) is
corrected to 40.00.
