3.2.8 DIRECT FUNCTION KEYS SUMMARY
Table 5 provides a brief summary of direct function key operation. It may be useful to keep
a copy of this summary near the RPM4, especially when first becoming acquainted with
its operation.
Local operation of RPM4 is through the front panel keypad. To minimize multi-layered menu
structures, the keypad numerical keys also provide direct access to the most commonly used
functions. The function accessed is labeled on the bottom half of the key. Direct function
keys are active whenever RPM4 is in its MAIN RUN screen. Table 5 summarizes the
operation of the direct function keys.

3.3 DIRECT FUNCTION KEYS
3.3.1 [RANGE]
 PURPOSE
To view and/or change the active pressure measurement range and associated settings.
 PRINCIPLE
An RPM4 range is defined as a pressure span and associated settings (see Section 3.2.3).
An RPM4 may have multiple ranges. Each Q-RPT in the RPM4 system has a default range
which is its maximum span. Additional ranges, lower than the Q-RPT’s maximum span, may
also be created using AutoRange (see Section 3.3.4). Ranges created using AutoRange
may be saved, with their settings, for reactivation (see Section 3.4.1).
The [RANGE] function key allows the available RPM4 pressure ranges to be viewed and selected.
