5.2.4 Setting the Display Average Times
• The display averaging times is the number of moving averages
calculated for instantaneous values (i.e., instantaneous mea-
surements excluding harmonics).
• The moving average is obtained by totaling the set number of
measurements and dividing the sum by the set number. After
the set number of measurements have been acquired, the
3169-20/21 discards the oldest measurement data every time
it acquires new measurement data, and continues to average
the set number of measurements.
