5.2 PACE Controller Connection for Output Sensor Calibration
1. Connect the output of the pressure calibration standard to the PACE modules as shown in
the diagrams.
Note: For gauge sensor calibration, apply both positive and negative gauge pressures to the
PACE outlet port.
2. For control module types CM0, 1 and 2, to attenuate changes in atmospheric pressure, or
changes due to drafts, connect the PACE reference port to the pressure calibration standard
reference port. Add a snubber (IO-SNUBBER-1) to the connecting pipe to prevent line
pressure changes due to temperature changes.

3. For control module type CM3, connect only the module outlet and supply +ve to the
calibration standard.

5.3 PACE Controller Connection for Barometric Sensor Calibration
1. Connect the output of the pressure calibration standard to the PACE module reference port.
WARNING Except for the barometric sensor calibration, connect the SUPPLY
+ port to the OUTLET port when calibrating the PACE controller module.
Failure to follow this procedure may result in the sudden uncontrolled release of
trapped pressure.
INFORMATION For optimum performance, connect the PACE reference port
to the pressure calibration standard with a snubber to atmosphere. This is not
normally necessary for pressure ranges of 7 bar and above.
