3.2.6 DIRECT FUNCTION KEYS SUMMARY

Table 3 provides a brief summary of RPM4 direct function key operation. It may be useful to

keep a copy of this summary near the RPM4/HPMS, 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 3 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. The default ranges of the RPM4 A70M/A20M are 10 000 psi

(A70M) and 3 000 psi (A20M). Additional ranges, lower than the Q-RPT’s maximum span,

may also be created using AutoRange (see Section 3.3.4) or AutoTest (see Section 3.3.10).
