    5 Start-up and Calibration Start-up and Calibration Remote Controller and Menu Sequence 5.1.1 Initial Start-up The device is factory-calibrated and ready for use. The device provides a 4 - 20 mA output signal that can be used in conjunction with data acquisition controllers. The digital HART signal that is superimposed on the 4 - 20 mA output can be read by control systems that are in compliance with HART Revision 7.0 format.
  • Page 22 Transient Fault conditions will be automatically cleared when the unit recovers from the fault condition. MSA recommends verifying proper response to changes in mA outputs by using the "Enter Fixed Current Mode" command described in the PrimaX IR Link Help Guide to check the four fault conditions noted with a * above. These checks should be done at every calibration phase.

  • Page 23: Primax Ir+ Calibration

    PrimaX IR+ Calibration The device can be calibrated using either the optional calibration cap locally at the sensor, or using the HART digital interface. NOTE: MSA recommends using a calibration gas value in the middle of the measuring range for optimum calibration.

After completing the zero calibration, perform a span check to ensure proper operation. For a span check, apply a gas of known concentration and verify that the measured response is within acceptable limits.
