Multi-Point Calibration
13. Move pointer to Flow Rate and press ENTER to open
a field edit window and enter the maximum flow rate
observed during the run. Press ENTER.
14. Continue proving at various flow rates using additional
Point Numbers and repeat procedure (return to Step
8) for each additional number. A minimum of three
points is recommended (high, medium, and low flow
rates) to obtain a good fit to the meter’s curve.
All ten points can be used to obtain optimum results.
Any unused points should be left at “ 0.00” for Flow
Rate and 0.000 for Percent Error.
15. When all the required points have been calibrated,
move pointer to Linearization Mode and press
ENTER to open a list box window and select Applied.
This puts Linearization algorithm into effect. If the
error message ADJACENT POINTS OUT OF 0.25%
RANGE is displayed, Applied function will not take
effect and more points will need to be added to ensure
that no two adjacent points, based on flow rate, are
more than 0.25% apart in their corresponding Percent
Error fields.
When Linearization is complete, press Cnfg (F4) to return
to Screen 7 on page 28, or press Main (F5) to return to
Screen 2 on page 20.
From
Screen 7, move pointer to Diagnostics and press
ENTER to advance to Screen 11a on page 48.
