Calibration
February 2017
If the low bleed relay option has been ordered stabilization may take approximately two minutes longer than the
standard relay.
Relay A may also be adjusted for use in single‐acting‐ direct applications. Rotate the adjustment disc as shown in figure
5‐1 for single‐acting direct operation.
Single‐Acting Relays
WARNING
For instrument level PD and PST only:
If the unused port is monitoring pressure, ensure that the pressure source conforms to ISA Standard 7.0.01 and does not
exceed the pressure supplied to the instrument.
Failure to do so could result in personal injury or property damage caused by loss of process control.
Single‐Acting Direct Relay
The single‐acting direct relay is designated by "Relay C" on a label affixed to the relay itself. Relay C requires no
adjustment.
Single‐Acting Reverse Relay
The single‐acting reverse relay is designated by "Relay B" on a label affixed to the relay itself. Relay B is calibrated at the
factory and requires no further adjustment.

Supply Pressure Sensor

Note
The pressure sensor is calibrated at the factory and should not require calibration.
To calibrate the supply pressure sensor, connect an external reference gauge to the output side of the supply
regulator. The gauge should be capable of measuring maximum instrument supply pressure. Follow the prompts on
the Field Communicator display to calibrate the instrument's supply pressure sensor.
1. Select a) Zero Only, or b) Zero and Span (gauge required).
a. If Zero Only calibration is selected, adjust the supply pressure regulator to remove supply pressure from the
instrument. Press OK. Once calibration is complete, go to step 5.
b. If Zero and Span calibration is selected, adjust the supply pressure regulator to remove supply pressure from the
instrument. Press OK. Adjust the supply regulator to the maximum instrument supply pressure. Press OK.
Proceed with step 2.
