7.2 Calibration Kit
The following steps must be performed when conducting a calibration verification test (bump
test) and calibration
to ensure proper performance of the monitor. Failure to do so may
adversely affect product performance.
• When performing a calibration verification test (bump test) and calibration only use
certified calibration gas at the required concentration level.
• Do not test with expired calibration gas.
• Do not cover or obstruct display or visual alarm cover.
• Ensure sensor inlets are unobstructed and are free of debris
Failure to follow instructions outlined in this user manual can result in sickness or death.
A Field Calibration Kit, CD6B-FCK, is needed to complete a field calibration. These are available through local
distribution.
• Gas cylinder –
o 17L 400 ppm carbon dioxide (CO
2
) in air
o 17L 5% volume carbon dioxide (CO
2
) in air
• Gas regulator 0.2 LPM
• About two feet of tubing
• CD-6-CH calibration hood
• Carry case
FCK Information
Several detectors can be calibrated with one FCK. The only limitation is the amount of gas in the cylinder. The 17-
liter cylinder has approximately 85 minutes of continuous calibration run time. Replacement cylinders are available.
