• Check calibration of your instrument annually to ensure it meets original performance specifications
• Keep your instrument dry. If it gets wet, wipe dry immediately. Liquids can degrade electronic circuits
• Whenever practical, keep the instrument away from dust and dirt that can cause premature wear
• Although your instrument is built to withstand the rigors of daily use, it can be damaged by severe
impacts. Use reasonable caution when using and storing the meter.

While the sensors have an expected life of more than five years in normal use it is recommended that the
analyzer is re-calibrated annually. This is so that long-term drift can be eliminated. Local regulations may
require more frequent re-calibration and users should check with appropriate authorities to ensure
compliance with relevant guidelines.

Periodically clean your instruments case using a damp cloth. DO NOT use abrasive, flammable liquids,
cleaning solvents, or strong detergents as they may damage the finish, impair safety, or affect the reliability of
the structural components.

The in-line water trap should be checked and emptied on a
regular basis. Water vapor will condense in the probe line,
which may cause the water trap to fill suddenly if the probe
is moved. Care should be taken at all times.
Carefully un-screw the plug from the bottom of the
water-trap housing. Dispose of the condensate in a suitable
drain, care must be taken as it could be acidic. If conden-
sate spills onto the skin or clothing, clean off immediately
using fresh water, seek medical advice if problems occur.
Ensure plug is replaced before performing combustion
tests. Note: CO2 reading will be low if the Water Trap
Plug is not in place.

This is a very important part of the analyzer and should be changed regularly. It prevents dust and dirt
particles from entering the pump and sensors that will cause damage. The filter MUST be changed when it
appears discolored on the inner surface.
Remove water-trap assembly from the analyzer as shown
above. Remove the filter and plastic holder from the housing.
Discard the filter element but keep the holder to fit to the new
filter. Clean the inside of the filter housing with a suitable soft
cloth. Fit the holder onto the new filter element and then insert
into the housing. Refit the housing onto the analyzer.
