Select Flow Point Values
(Multiple MFs)
When calibrating with multiple meter factors, it is essential that you
proceed in steps, first calibrating product at a low flow rate and then
proceeding to progressively higher flow rates. Calibrating the product at
low flow rates ensures that inaccuracies at lower flow rates do not get
added when calibrating at a higher flow rate.
Note: This sequence shows the screens for multiple meter factors.
First, select the number of flow rate set points (a minimum of 1 to a
maximum of 12) with which to calibrate the product. The system
updates the No of Points of Meter Factor Linearization parameter
[63,0,109] based on the number of set points you define.
For example, if you define four set points, the system sets the parameter
[63,0,109] to 4, which also becomes the highest flow rate set point.
(Flow rate 1 is the lowest and flow rate 4 is the highest.) The number of
flow rate set points you define applies to all components in the system.

Press ENTER to continue (or press EXIT to return to the MF/K-factor
option screen.) The system then shows a screen summarizing the flow
rate and mater factor associated with the selected set points:

Press ENTER to continue (or press EXIT to redisplay the maximum
flow rate set point screen). The system prompts you to accept or edit the
displayed values. For this screen, you can edit the flow rate and the
current meter factor. The component and meter values cannot be
changed.
Press  and  to move between the flow rate and meter factor values.
If you are satisfied with the displayed values, press ENTER to move to
the next screen.
After you press ENTER, the system verifies that all flow rates are still
in ascending order (that is, flow rate 1 < flow rate 2 < flow rate 3 < flow
rate 4) and that no flow rate is less than zero.
