Calibration
Example
To adjust meter factors:
• With the EDD, bus parameters, or ProLink II, refer to the menu flowcharts in Figure 3-8.
• With the display, refer to the menu flowchart in Figure B-12.

The flowmeter is installed and proved for the first time. The flowmeter
mass measurement is 250.27 lb; the reference device measurement is
250 lb. A mass flow meter factor is determined as follows:
MeterFactor
The first mass flow meter factor is 0.9989.
One year later, the flowmeter is proved again. The flowmeter mass
measurement is 250.07 lb; the reference device measurement is
250.25 lb. A new mass flow meter factor is determined as follows:
MeterFactor
The new mass flow meter factor is 0.9996.
