OI/RVG200-EN
Select the filter to be applied to the electrical input prior to sampling.
Note.

Applicable to analog sources only.

Filters are applied to the recorded values shown on the Chart view
only, not to instantaneous values displayed on the channel
indicators.
Instantaneous – A single value based on process conditions at the
time of sampling.
Average – The average value of the analog signal since the
previous sample.
Minimum – The minimum value of the analog signal since the
previous sample.
Maximum – The maximum value of the analog signal since the
previous sample.
Max & min – Two values are recorded to capture the maximum and
minimum signal values since the previous sample.
This allows the memory use to be extended by
permitting a slower sample rate to be selected
without losing the transient behavior of the signal.
