A calibration adjustment can be made by using the
“OFFSET BY” or “SET TO” method. In either case, keep the
sensor in the process measuring the flow rate.
This proce-
dure is only for Sensor A. Make calibration adjustments
for other sensors in the same way using their respective
sensor menu screens.
