4.10 Setting the Averaging
(Time averaging/Moving averaging/Exponential averaging)
This unit provides three averaging functions. The time average outputs the
average over a fixed time interval, and the moving average and exponential
average provide values which reflect the previous values.
･
This setting applies to all channels together. It is not possible to make
separate settings for each channel.
･
This function does not affect the harmonic analysis/flicker function.
･ The D/A outputs give the values obtained by averaging.
･ Waveform peak measurement values are not averaged.
･
If [TYPE1] is selected as the calculation type while using averaging (time
averaging, moving averaging, or indexed averaging), the "si" and "su"
polarities for each channel are calculated as +1.
･
Calculation is performed 16 times per second.
(1) Setting the Time Average (AV-T)
The time average function sequentially sums the data values obtained during
the time interval (interval control time, timer control time, or real-time
control time), and divides by the number of samples. This can be used, for
example, while integrating at particular intervals, to output the average of
some other measurement value during those intervals.
