Tips: Precautions for carbon dioxide gas detector calibration.
- The calibration personnel must be trained, understand the principle and performance of carbon dioxide gas detector, be proficient in operating skills, and hold a certificate.
- The adjustment personnel must strictly follow the operating procedures.
- CO2 gas detector must be measured and appraised and can be used only after it is qualified.
- Before calibrating the carbon dioxide gas detector, perform a visual inspection. Calibration can be started after confirming the appearance is intact.
- CO2 gas detector that needs to be calibrated should be warmed up for about 20 minutes. Zero the carbon dioxide gas detector in fresh air.
- After the zero adjustment is completed, pass a standard gas sample with a concentration of about 1.0% according to the flow specified in the manual. Calibrate the displayed value of the carbon dioxide gas detector. The indicated value is consistent with the standard gas value and can be used after it is stable.
