Process standardization configuration
Standardization adjusts the system by resetting one point of the calibration curve to an
independently measured or known level.
The frequency of standardization depends on several factors, including desired accuracy of
the reading.
Set up the following sub-parameters for standardization:

STANDARDIZE_POINT

STANDARDIZE_TYPE
Standardize point
Process value recorded for the last standardization.
Standardize type
Process standardize type determines how you enter the actual process value of a
standardize sample. If this is set as Use Lab sample value, the software screens prompts
entry of the sample value during a standardize. If this is set as Use Default value, the
software always uses the Default standardize level as the sample value.
Standardize default value
Default standardize is the default level value in engineering units that you use in the
standardization procedure. At standardization, enter the actual level of the process material
to override this default.
Standardize interval
Standardize interval is the interval in days between standardize alarms. The level transmitter
alarms to indicate that a standardize procedure is due if the diagnostic alarm, Standardize
due, is set.
