Adjusting Air Pressure
This procedure can be used for all pressure regulators on the M-2000 Series platform. You
must be in FmNT when adjusting the gauges and regulators.
1. Make certain that the dispensing system is ON.
2. The beacon system status should be yellow or green.
3. Locate the pressure regulator knob on the gauge and regulator set.
4. Rotate the knob as follows while watching the gauge:
 To increase pressure, rotate the knob clockwise until the gauge registers the
desired pressure.
 To decrease pressure, rotate the knob counter-clockwise past the desired
pressure, and then rotate the knob clockwise to the desired pressure. This has the
effect of increasing the desired pressure, eliminating the possibility of a false
reading.
