5.13 – K-FACTOR CONFIGURATION

Caution

In the majority of applications, the use of a K-Factor is neither required nor desirable.

Before using the K-Factor feature, contact the Service Department (see Section 10) to review

the application and obtain assistance in determining the K-Factor gain and bias values.

Turns K-factor function ON or OFF, calculate a K-Factor gain and bias from measured data, or select a K-Factor gain
value and K-Factor bias value.

Note:  If K-Factor is ON, Process displays will have an asterisk (*) after the description (i.e

. 

FLOW*

).
