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.

3.3DIRECT 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.
