CONFIGURATION
Select the filter to be applied to the electrical input prior to
sampling.
Notes.
• 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 or bargraphs.
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 & 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 behaviour of
the signal.
•1 If this parameter is changed, a new internal data file for this recording channel is created. All historical data stored internally for this
channel is lost.
