Accuracy Statement - Honeywell XT Series Operating Instructions Manual

16. Accuracy Statement

To achieve optimal accuracy, the detector should be periodically supplied with a known
concentration test gas, and if the readings are outside of 15% of the applied gas concentration,
a span calibration should be performed, under conditions of standard temperature (15°C to
25°C), humidity and pressure.
Poisons should not affect the accuracy of the XT but certain compounds can block the gas access
port of the sensor, such as silicone oils, giving a lower than expected reading.
