Wait until the current pressure counts are equal to or close to the target pressure counts,
minimum 2 minutes.

Measure the flow out of the detector vent on the back panel and compare
the measured value
with the target flow shown on the display. If necessary, use the ← key and the numeric keypad
to change the target pressure counts. Use the → key to update the new value. Wait for the
pressure counts to stabilize, at least 1 minute, and re-measure the flow at the detector vent.
Repeat until the measured flow is equal to the target flow ±2 cc/min.
