Pressing the
[+/-]
key or the
[RANGE]

through displays of the other available ranges, from lowest range to highest range.
To select a range to become the active range, press
[ENT]
while the range is displayed.
Pressing
[ESC]

making a range change.
Range full scale limits are given in the pressure unit that is currently active for that range.
Pressing [+/-] from the MAIN RUN screen provides a shortcut to a momentary view of the
active range.
Many RPM4 settings and functions are range specific. See Table 4 for identification of
range specific settings.
For best metrological performance, vent the RPM4 Q-RPT before changing ranges.
3.3.2
[UNIT]
PURPOSE
To select the unit of measure in which RPM4 displays pressure values.
For information on selecting the measurement mode (absolute, gauge, negative gauge,
differential), see Section 3.3.3.
PRINCIPLE
RPM4 allows the unit of measure in which pressure values are displayed to be changed.
RPM4 supports 15 standard pressure units of measure as well as user defined units.
To simplify operation, quick access to six units is made available under the
[UNIT]
key.
The default units available depend on whether the RPM4 was originally configured as an SI
or US version. The
[UNIT]
key contents can be customized by the user to any configuration
of six units (see Section 3.5.6).
