5.2 PACE Controller Connection for Output Sensor Calibration
1. Fit a blanking plug to the SUPPLY – input of the PACE controller.
2. Fit an on/off valve to the SUPPLY + input of the PACE controller. Leave the other side of the
valve open to atmosphere.
3. Turn the on/off valve to the closed position.
4. Connect the output of the pressure calibration standard to the PACE module output port.
Note: For gauge sensor calibration, apply positive and negative gauge pressures to the
PACE output port.
5. 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 - SNUBBER - 1 to the PACE reference port.
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
On completion of calibration, open the on/off valve (5) to vent
trapped pressure from the SUPPLY + port to atmosphere.
INFORMATION
For optimum performance, connect the PACE reference port
to the pressure calibration standard. If unavailable, fit snubber IO - SNUBBER - 1 to
the PACE reference port.
