RPM4 Q-RPT is active and the active measurement mode. See Table 7 or Table 8 for
definition of the types of units of measure are available by Q-RPT and measurement mode.
The choice of six units displayed by the
[UNIT] function can be customized by the user (see
Section 3.5.6).

Internally, RPM4-AD always operates in Pascal (Pa), the SI unit of pressure. Values
expressed in other units of measure are obtained by applying conversion or scaling factors to
Pascal. (see Section 7.2).
 OPERATION
To change the active unit of measure for a Q-RPT and
measurement mode, press
[UNIT] from the MAIN
RUN screen while the Q-RPT and measurement
mode is active (see Table 9 or Table 10 for default
units of measure by active Q-RPT and measurement
mode). The display is (actual units shown specific to
Q-RPT and measurement mode):
1kPa 2inHg 3psi
4mbar 5m 6ft
The cursor is on the number corresponding to the active pressure unit of measure for the active range.
To change the pressure unit of measure, select the desired unit. Making the selection
returns to the MAIN RUN screen with the selected unit active.
