Position Identification of Q-RPTs In a PPC3 System
Position identification of the currently active Q-RPT or utility sensor in the PPC3 system is
continuously displayed in the upper right hand corner of the PPC3’s MAIN RUN screen and
most other screens. See Table 3 for position designation protocol for the Q-RPTs available in
a PPC3 system.
See Table 1 for a complete listing of Q-RPTs available and their default ranges.

3.2.5 MULTIPE RANGES (Q-RPTS, AUTORANGE AND INFINITE
RANGING)
A PPC3 range is defined as a pressure span and associated settings.
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 span. Additional ranges, lower than the
Q-RPT’s maximum span, may be created using AutoRange (see Section 3.3.4). Ranges created
using AutoRange may be saved with all their settings for reactivation later (see Section 3.5.1).
A PPC3 range is identified by a range screen showing the Q-RPT used by the range, its current unit
of measure and its full scale pressure in gauge and absolute (if available) measurement modes.
1. Q-RPT or utility sensor designator.
2. Type of range. DF for the Q-RPT’s default range; AR for a range
created by AutoRange.
3. Q-RPT or utility sensor position designator.
4. Current pressure unit of measure.
5. Full scale pressure in current unit of measure in gauge and/or
absolute measurement mode depending on type of Q-RPT and the
measurement modes available.

Most settings made in a PPC3 range, such as unit of measure, measurement mode, display
resolution, control mode and control parameters are specific to the range. Many settings
made while a range is active apply to that range and not other ranges. The range specific
