Hart Module - MSA PrimaX IR+ Operating Manual

8 Ordering Information
Calibration of the device mounted in an air duct must be done with the HART interface. Once calibration has been
initiated, apply the calibration gasses via the gas calibration port. Ensure that the duct is free of all gases to which the
sensor will respond and the duct flow rate is below 1 m/s. If hydrocarbon combustible gas is present in the duct, the
sensor must be removed from the duct during calibration. The sensor can be removed from the duct mount bracket via
four screws.
