9. Once the automatic calibration process has started, the screen below will be
displayed. As the flow becomes stable at each point, the unit will collect a data point
once per second until the STABILTY counter reaches 8. If the system becomes
unstable during this process, the STABILITY counter will reset and the process will
begin again until all 8 data points can be gather will the system is stable. These data
points are then averaged and used as one of the five data points for the flow
calibration. If the system has difficulty becoming stable, the “F1” key can be pressed
to force the system to take data and move on to the next point. This may result in a
less than optimal calibration, but may be required in some situation (like calibration
the system in high winds). The unit will automatically return to the main calibration
screen once all five data points are collected. Pressing the “ESC” key will abort the
process and return to the main calibration screen.

10. Once back at the main calibration screen, the R value should be examined. It should
be greater than 0.99. If it is not, try calibrating again. Press the F4 (EXIT) soft-menu
function key to exit the calibration process.
