CEMS Block Average
Outputs a block mean average CVn OV over the specified Average Period. The average is calculated
from input samples taken at equally spaced Sample Periods. All samples are discarded at the end of
the Average Period and the Average Period begins again.
Samples are ignored when Calibrate Hold is ON(1). After the Average Period the new average is
calculated using only the samples taken before and after the Hold. If no valid samples are taken, the
output maintains its previous value.
Table 4-48 describes the CEMS Block Average prompts. See Table 4-2 for additional prompts.

CEMS Rolling Average (CEM Rolling Avg)
Outputs a rolling mean average CVn OV over the specified Average Period. Average is updated every
Frame Period thereafter. Samples are taken at every scan cycle of the instrument, except when
Calibrate Hold is ON(1).

Programming Function Blocks and Features
Enter the output's display limits. Output is not clamped or
flashed when it exceeds these limits.
Input to be averaged
When discrete is ON(1), average is reset to zero; when
ON(1)-to-OFF(0), average restarts.
Time units of the averaging period
Number of time units per average period.
Number of time units between samples. Must divide
evenly into Average Period.
When ON(1), no samples are taken and the output is held.
