The screen shown in
Figure 20
allows multiple actual flow rates
to be run past the meter and the values recorded by the TFXL.
To calibrate a point, establish a stable, known flow rate (verified
by a real-time primary flow instrument), enter the actual flow rate
in the
Figure 20
window and press the
Set
button. Repeat for as
many points as desired. Note: If only two points are to be used
(zero and span), it is preferred that a flow rate as high as
anticipated in normal operation is used as the calibration point. If
an erroneous data point is collected, the point can be removed
by pressing the
Edit
button, selecting the bad point and selecting
Remove.
Press the
Finish
button when all points have been gathered.
