Carbon Monoxide Gas Test

The following steps must be performed when conducting a calibration or calibration verification test (bump test) to ensure proper

performance of the monitor. Failure to do so may adversely affect product performance and result in sickness or death.

 When performing a calibration or calibration verification test (bump test) only use certified calibration gas at the

required concentration level. Do not calibrate with expired calibration gas.

 If the instrument cannot be calibrated, do not use until the reason can be determined and corrected.

 Do not cover or obstruct display or visual alarm cover.

 Ensure sensor inlets are unobstructed and is free of debris

General

A Field Calibration Kit, CM6-FCK, is needed to complete a CO gas test. These are available through your local representative or from

Macurco.

Contents of the FCK

 CM6-FCK: (2) Gas Cylinders, (1) 17L 50ppm carbon monoxide (CO) in air and (1) 17L 200 ppm carbon monoxide (CO) in air

 Gas regulator with about two feet of plastic tubing

 Humidifier

 CM-6-CH calibration hood

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. The gas cylinder should be replaced

when the pressure gauge on the regulator shows 25-psi or less.

Note: For optimum test results it is suggested that the unit be in clean air, green light on, and be in a low ambient air flow
