3.3 DIRECT FUNCTION KEYS
3.3.1 [RANGE]
 PURPOSE
To view and/or change the active pressure measurement range and associated settings.
[RANGE] selects from existing ranges. See [AutoRange] to create ranges (see Section
3.3.4).
 PRINCIPLE
A PPC3 range is defined as a pressure span and associated settings (see Section 3.2.5).
A PPC3 may have multiple ranges. Each Q-RPT (and the utility sensor if present) available
to the PPC3 system has a default range which is its maximum full scale. Additional ranges,
lower than the Q-RPT’s full scale, may also be created using AutoRange (see Section 3.3.4).
