The analyzer has been calibrated at the factory and is designed to maintain calibration accuracy for
extended periods of operation. We recommend a calibration about every three months to ensure the
integrity of the analyzer. Some regulatory agencies specify the time intervals between calibrations
based on your application. It is important to comply with the governing regulations for your industry.

For high-pressure cylinders of gas, a regulator is needed to monitor the pressure of the calibration gas
bottle and to adjust it to the pressure required for testing and calibration. An external sample
conditioner often is used to provide pressure regulation and flow control.
NOTE: When using calibration gas, the bottle should be kept at about 21°C [70°F] for 8 hours
prior to use. Sudden temperature changes can condense some of the components in the bottle,
changing their concentration.
For detailed steps on the Calibration procedure, see Configuring the Analyzer herein.

To maintain the appearance of the analyzer and prevent the buildup of dirt on the touchscreen,
periodically clean the exterior with a soft damp cloth. Use a mild detergent to remove grease.
CAUTION: DO NOT USE CLEANERS SUCH AS ACETONE, BENZENE, CARBON TETRACHLORIDE,
GASOLINE, OR TOLUENE, AS THEY CAN DAMAGE PLASTIC COMPONENTS AND AFFECT
ANALYZER ACCURACY IF THEY CONTAMINATE THE SAMPLING SYSTEM.
