4. Setup
The CM-6-CH calibration hood is designed for easy attachment to compatible Macurco CO detectors. Follow these general steps for setup:
- Ensure your Macurco CM-6 or CM-12 detector is properly installed and powered.
- Carefully align the CM-6-CH calibration hood with the sensor area of the detector.
- Securely attach the hood to create a sealed environment around the sensor. Refer to your detector's manual for specific attachment points or methods.
- Connect the calibration gas cylinder to the inlet port on the calibration hood.
5. Operating the Calibration Hood
The calibration hood facilitates the application of a known concentration of CO gas to the detector's sensor for accurate calibration. Always follow the calibration procedure outlined in your Macurco CM-6 or CM-12 detector's specific user manual.
General Calibration Steps:
- With the calibration hood securely attached and the calibration gas connected, initiate the calibration sequence on your Macurco detector.
- Open the valve on the calibration gas cylinder to allow the gas to flow into the hood and over the sensor.
- Monitor the detector's display and indicators as per its manual until the calibration process is complete.
- Once calibration is confirmed, close the gas cylinder valve and remove the calibration hood.
The detector is designed to operate within a temperature range of 0 to 35°C (32 to 95°F) and a CO detection range of 0-200 PPM. Ensure your calibration environment adheres to these specifications for optimal results.
6. Maintenance
The CM-6-CH calibration hood requires minimal maintenance. Keep it clean and free from obstructions to ensure proper sealing during calibration.
- Wipe the exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Ensure the internal surfaces that contact the detector are clean and free of debris.
- Store the calibration hood in a clean, dry place when not in use to prevent damage.
- As indicated on the product, do not paint the device.
7. Troubleshooting
If you encounter issues during calibration, consider the following:
- Calibration Failure: Ensure the calibration hood is securely attached and creating a proper seal. Verify the calibration gas cylinder is not empty and the flow rate is correct.
- Inaccurate Readings: Check the expiration date of your calibration gas. Ensure the ambient temperature is within the specified operating range for the detector.
- Physical Damage: Inspect the calibration hood for any cracks or deformities that might prevent a proper seal. Replace if damaged.
For persistent issues, refer to the troubleshooting section of your Macurco CM-6 or CM-12 detector manual or contact Macurco technical support.
