TOTALIZER INTEGRATION RATE—Determines the rate
at which the Totalizer is updated.
SECOND —Engineering units per second
MINUTE—Engineering units per minute
HOUR—Engineering units per hour
DAY —Engineering units per day
MIL/DAY—Millions of units per day
ATTENTION
The source of the Totalizer is averaged
over the sample and update rates. For example, since the
loop cycle speed is six per second, then with the Totalizer
Rate set at once per minute, the source is averaged six
times per second and the Totalizer value is updated with
this average value ÷ 60 once per second.
NOTE 1: Does not apply to Three Position Step Control.
NOTE 2. If the calculated value of the quantity under the square root sign decreases to a value less than 0.010, the
calculation will become linear as the calculated value decreases below 0.010.
