Analyzer calibration must be verified on a weekly basis. Improper calibration may result
in an incorrect reading, exposing the user to dangerous levels of carbon monoxide.
Exposure to carbon monoxide can lead to unconsciousness and death.
This Analyzer must always be checked against a calibration gas and used with gases
regulated and supplied at atmospheric pressure (0 psi). Use of gases at higher pressures
may result in incorrect readings and may damage the Analyzer. Incorrect readings may
expose the user to high levels of carbon monoxide resulting in personal injury or death.
Checking Calibration or use of the Analyzer with a low battery may result in inaccurate
readings. Inaccurate gas analysis can lead to serious personal injury or death.
If the Analyzer has been subjected to a recent change in ambient temperature, allow it to
stabilize for one hour before checking calibration.
Verify calibration on a weekly basis. Breathing gas applications require the use of a certified CO
calibration gas with a 10 ppm concentration and flow rate of 1.0-5.0 L/min. The equipment to
produce this flow is available from Nuvair. See Spares and Accessories section.
To assure the greatest accuracy for other applications, use the calibration gas concentration
closest to the expected concentration in the gas being measured.
