5.2 Averaging Function
110
The averaging function averages measured values and displays the result. This function can be used to
obtain more stable display values when measured values fluctuate and cause large variations in the dis-
play.
Performs averaging on all instantaneous measurement values, including harmonics and motor sync
source.
Averaging setting can be selected from the following.
* Period to be within the accuracy when the input changes from 0% to 100%f.s.
Averaging Method • Index averaging (applicable to 50 ms data update rate)
• Averaging is applied to voltage (U), current (I), and power (P), before perform-
ing calculations.
• For the harmonics, RMS values and percentage are calculated in average to
instantaneous values, and the phase angle is calculated in average of real part
and imaginary part after FFT calculation.
• Phase differences, distortion ratios and unbalance ratios are calculated from
the data averaged as above.
