The DISPLAY selection is Q-RPT specific. A DISPLAY selection made in one Q-RPT does
not apply to other Q-RPTs.
The default DISPLAY function is Rate which causes the second line of the display to show “R”
followed by the current rate of change of pressure in current pressure units per minute or
per second. In differential mode (<Hd>), the default DISPLAY function is RPT which
shows the measurement of the Lo Q-RPT .

The Average DISPLAY has a second screen that allows the instantaneous
pressure readings to be viewed while an averaging cycle is running.
The instantaneous Average screen is:
1. Instantaneous pressure values at RPM4’s
normal update rate.
2. Current rate of change of pressure in pressure
units/second.
3. Countdown in seconds until completion of on-
going averaging period.
