How The Inspector Works; How To Perform A Self Calibration - Sensorcon CO Inspector Product Manual

HOW THE INSPECTOR WORKS:

An electrochemical sensor behind the sensor inlet shown in the image above will create an electrical signal when
carbon monoxide (CO) is sensed. The gas concentration is displayed in parts per million (PPM).
Please Note: The Sensorcon Inspector is a professional tool. It does not require very much maintenance with the exception of keeping it clean.
This is especially important in the area of the sensor inlet. If it gets dirty then simply wipe it clean with a damp cloth or with a damp cotton swab.
Hold down both buttons to begin.

HOW TO PERFORM A SELF CALIBRATION:

For reasonable accuracy a frequent calibration is recommended at least once every 6 months. Sensorcon will
perform this procedure for you or you can do it yourself if you have the necessary 50ppm calibration gas.
Please follow these steps to self calibrate your Inspector:
1. Hold both buttons for 5 seconds to enter calibration mode. Press the MUTE button at any time to exit.
2. In a clean air environment then press the MAX button to begin the ZERO calibration. Wait for countdown.
3. When zero is complete, use 1/4" OD, 1/8" ID Tygon tubing attached to the calibration gas cylinder and
sensor inlet to flow calibration gas at 0.5L/min, then press the MAX button to start calibration process.
4. The Inspector will then automatically calibrate itself and notify you if a calibration is successful.
Please feel free to contact us if you have any further questions or are in need of technical assistance.
