13.2 Parameters and their setting ranges
♦ <Averaging time>
The averaging time parameter defines the time period over which the
RMS measurement value will be averaged. The averaging time can be
changed within its setting range. The setting range is from 25 ms to
204,800 ms. The step size doubles at each step for defining the
averaging time. This gives the setting options:
25 ms, 50 ms, 100 ms, 200 ms, ... 51.2 s.
Averaging time Minimum: 0.025 s Maximum: 51.2 s
Works pre-setting 0.8 s
Setting advice:
Longer averaging times improve the reproducibility and reliability of the
measurement at the cost of time resolution.
Conversely shorter averaging times increase the time resolution at the cost
of reproducibility.
The extreme short averaging times of 25 ms and 50 ms should be used only
in special applications. If the signal to be evaluated has a fundamentally low-
frequency energy content, the measurement result will be very unstable.
This instability can be prevented only if the averaging time is selected longer
than the longest period in the signal.
