  • Page 12: Calibration

    3. Calibration The calibration process adjusts the instrument measured value so that the span point and zero point during O measurement match the sensor output when the reference gases (atmosphere, nitrogen) were measured. Perform span calibration once a day before starting measurements. Ideally, span calibration Span calibration should be performed when the temperature of the oxygen sensor and temperature sensor are sufficiently stable, such as first thing in the morning before operating the air conditioning...

  • Page 13: Zero Calibration

    To accurately measure low concentrations when measuring O , use nitrogen gas for calibration. Zero calibration Set the needle so it can suction the nitrogen gas. Press The MENU screen opens, and “CAL” is selected (flashes). Press The O CAL screen opens. * If even one measurement has been taken, the previous measured value will display.

    Checking for clogging [CLOG CHECK] If the gas path, such as the needle or tubing, is clogged, the gas cannot be suctioned properly, and correct measurement cannot be made. A clogging check is performed to check for any clogging. The clogging check makes a decision using the pressure sensor that is built into the gas path. If the gas path is not clogged, the pressure will be between 0 and -5kPa.
