Sidestream CO2 Calibration Test
Sidestream CO
2
Calibration Test
This test checks the calibration of the Microstream CO
2
gas measurement. The CO
2
calibration test is required after the first 1,200 hours of use or one year, whichever
comes sooner. After the first calibration, calibrate after 4,000 hours of continuous use
or every year, whichever comes sooner. In addition, perform the calibration tests when
the instrument is repaired or when parts are replaced.
Note — Replace the CO
2
module after 20,000 hours of use.
The CO2 Test menu also displays the following information about the Sidestream CO
2
module:
• Hardware version
• Firmware version
• Last calibration date
• CO2 usage hours
• Hours to calibration
• Hours to service
Caution If the initial calibration is performed before 720 hours of use, the module resets to
require the next calibration after 1,200 hours instead of after 4,000 hours.
This test uses calibration equipment that you can order. Refer to the documentation
accompanying the calibration equipment for more details.
Warning A monitor that is not calibrated at the recommended intervals may provide
inaccurate results.
Dispose of empty or partially empty calibration gas containers in accordance with
the manufacturer’s instructions and local regulations.
