1. Press A1 until "AvG" is displayed, then release A1.
2. Press A2. The current setting will be shown. This is a value between 1-16, and indicates
how many flow samples are averaged (moving average window size) to calculate the
output.
3. Press A1 to toggle between the values.
4. Press A2 to select the desired selection.
5. The LCD will show "End" and the unit returns to normal operation.
 Each flow sample takes about every 5 milliseconds to complete. The "AvG" value is
the size of the moving average array, allowing for 1 to 16 samples to be averaged
when the output is calculated. This is used to slow down the flowmeter response
time, and provide a smoother output. In some applications where the flowmeter is
used in a feedback loop to regulate flow, if the response time is too fast the system
starts oscillating.
 The delay setting is only used when the meter operates in "LS" (Low-Speed) mode.
It is ignored in "HS" (High-Speed) mode.
