5.4 PACE Indicator Connection for Input Sensor Calibration
1. Connect the output of the pressure calibration standard to the PACE input port.
Note:
For gauge sensor calibration, apply positive and negative gauge pressures to the
PACE input port.
2. To attenuate changes in atmospheric pressure, or changes due to drafts, connect the PACE
reference port to the pressure calibration standard reference port. If a reference connection
is unavailable, fit snubber IO

5.5 PACE Indicator Connection for Barometric Sensor Calibration
1. Connect the output of the pressure calibration standard to the PACE reference port.
6. Calibration Check
Note:
The PACE adds the barometric reading to a gauge range to produce a pseudo-absolute
range (for CM2 and below). For CM3 the PACE adds the barometric reading to an absolute range
to produce a pseudo-gauge range.
For PACE calibration menus, refer to Appendix
To check the calibration of PACE, proceed as follows:
1. Connect the PACE to the pressure calibration standard. Refer to Section
2. Press

INFORMATION
For optimum performance, connect the PACE reference port
to the pressure calibration standard. If unavailable, fit PACE snubber

INFORMATION
Gauge ranges (for CM3 8 bar absolute ranges and above see
Section 8) should be zeroed immediately prior to a calibration check. Zeroing is
not required for CM3 2 bar / 3.5 bar.
