Apparatus for performing sensor calibrations and bump tests

A system configured for performing sensor calibrations and bump tests comprising:

• a sensor configured to measure properties of a gas:
• a housing having a gas inlet and a gas outlet, wherein a first gas path is defined between the gas inlet and the gas outlet through the housing, and a second gas path is defined between the gas inlet and the gas outlet through the housing, wherein a filter is provided along the first gas path to filter the gas passing therethrough, at least one valve provided between the gas paths and the gas inlet, wherein gas flows through the first gas path upon activation of the at least one valve to a first condition, and wherein gas flows through the second gas path upon activation of the at least one valve to a second condition:
• tubing coupled to the gas outlet:
• a calibration cap coupled to the tubing and to the sensor;
• and
• a gas standard bottle coupled to the gas inlet.

A method of operating an apparatus for performing sensor calibrations and bump tests comprising:

• connecting a gas standard bottle to an apparatus:
• connecting a calibration cap of the apparatus to a sensor configured to sense properties of gas:
• turning the gas standard bottle on to allow gas to flow out of the gas standard bottle and into the apparatus:
• activating at least one valve of the apparatus to allow gas to flow along a first gas path through the apparatus to the calibration cap and to the sensor, wherein the first gas path includes an inline filter through which gas flows:
• commencing a calibration program of the sensor to perform a baseline collection:
• after completion of the baseline collection, activating the at least one valve to allow gas to flow along a second gas path through the apparatus to the calibration cap and to the sensor, wherein the second gas path does not have an inline filter through which gas flows;
• after a gas response collection performed by the sensor has been completed, disconnecting the calibration cap from the sensor;
• and
• ending the calibration program of the sensor.
