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 behavior of the signal.
Select a signal source to enable/disable recording of the
A
channel data. Refer to Appendix A, page 108 for a description
of the available sources.
Note. This signal is edge-triggered. A rising edge (inactive to
active) enables recording. A falling edge (active to inactive)
disables recording.
