H. Totalize -
The totalize calculation keeps a
running total of the value of a point sampled at a
fixed rate. This will continue until the programmed
reset interval time is reached at which time the
value is logged on the alarm/event log window (if
reset print is enabled), is reset to zero, and the
Totalization calculation begins again. However, a
low-flow cutoff provision prevents totalization on
flow rates that meet or fall below the cutoff point.
The data will also be recorded to disk if alarm/event
logging is enabled. The totals are non-volatile for
channels A, B, and C unless auto reset is active.
