TOTALIZER INTEGRATION RATE
—Determines
the rate at which the Totalizer is updated.
SECOND
—Engineering units per second
MINUTE
—Engineering units per minute

—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, as 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.

POLYNOMIAL EQUATION
—A fifth order Polynomial
Equation can be used on any one of the five Analog
Inputs.
The equation is in the form:
Y = C0 + C1 X + C2 * 10-1 X2 + C3 * 10-3 X3 + C4 * 10-5 X4 + C5 * 10-7 X5
Where:
X
is the value of the input in % of span
C0 is a value between –99.99 to +99.99
C1 – C5 are values between –9.999 to +9.999
Ratio and Bias can be applied on the “Y” output term as
follows:
Calculated “Y” Value = Y * Input X Ratio + Input X Bias
After the Polynomial is enabled, refer to the prompts listed
below and enter the coefficients.
