Perform Factory
The option is used only by the factory for initial compensation.
Requirements for Field Compensation
Recommended Meter RPM
15 - 1000
Minimum Acceptable RPM
10 (LOW FLOW error displayed if lower)
Maximum Acceptable RPM
1350 (HIGH FLOW error displayed if higher)
Maximum Allowable Flow Ripple
3% (or UNSTEADY FLOW error displayed)
Activating Selected Compensation
After selecting the desired compensation option, the PROCEED WITH OPTION button must be pressed. This initiates the
compensation, during which the Status Bar will turn yellow (In Progress, may take up to 1 minute). Upon completion the
Status Bar will turn grey and display the results of the compensation.
Linearization Data
The displayed values are from the Raw Factory Calibration of a flow meter. They are NOT the values shown on
the Calibration Certificate provided with the flow meter. Typically, the linearization table is programmed into the
transmitter/meter assembly at the factory and will not need to be modified by the user, except in the following cases:
a) After performing a field calibration of the flow meter.
b) During a field replacement of the transmitter where the customer wishes to enter the linearization data.
In this case you must request the Raw Factory Calibration Report be sent
to you for the flow meter (the flow meter serial number is required) or note the values
entered into the original transmitter’s linearization data fields. The factory can also load
K-factor data into a replacement transmitter before shipment.
Analog Calibration
This data is collected on analog transmitters using high accuracy measurement equipment and provides precise
calibration of the onboard circuitry.
