Touch to change the amount of data displayed on the screen. A longer
screen interval displays more data, a shorter screen interval displays data
over a shorter time period, but in more detail. In both cases, the full trace is
preserved by plotting the maximum and minimum samples for each display
point.
Longer interval =
better overview
The screen intervals available in the menu are determined by the faster of
the primary and secondary sample rates set for the process group during
configuration – see Section 7.8.1, page 80.
Table 4.1 shows the relationship between sample rate and screen interval
for the vertical and horizontal chart views.

A 'Please Wait' message appears in the status bar while the recorder
retrieves data from storage.

Selecting a different screen interval does not affect the rate at which
data is sampled.
