this channel is lost.

OR
Each recording channel can be configured to position its trace in
a specific zone in the vertical or horizontal chart views in order to
separate traces that would otherwise be very close to each
other.
Select one of the 15 pre-defined or 10 custom zones available –
see Section 6.8.2, page 108 for custom zone configuration
details.
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
behavior of the signal.
