  • Page 41: Section 6 Calibrations

    Section 6 Calibrations 6.1 Atmospheric pressure equilibrium Since the instrument is sealed against moisture, you must open the barometric pressure sensor relief valve switch on top of the instrument (refer to Figure 1 on page 17 for actual location) to permit the instrument to achieve atmospheric pressure equilibrium, and take an accurate barometric pressure reading.

  • Page 42: Sensor Calibration

    Calibrations 6.4 Sensor calibration When delivered, the sensor is pre-calibrated. However, it should be re-calibrated on site, when being used for the first time, and always after a membrane change. If you have just replaced the membrane, allow at least half an hour for the membrane to settle before attempting to calibrate. If you want to verify the accuracy of the calibration, place the analyzer back in measurement mode and compare your displayed gas concentration against the value in the appropriate tables found in the accompanying Calibration Tables booklet.

  • Page 43: Calibration In Line

    Calibrations 6.4.2 Calibration in line The in line calibration procedure can be used to calibrate the sensor directly in line, against a liquid sample with a known dissolved gas concentration. To perform this type of calibration, the instrument must be set for calibration In line. Switch on the instrument, if necessary, and wait a minute or so for the displayed measurement to settle.

  • Page 44: Calibration In Air (Oxygen Sensors Only)

    Calibrations 6.4.3 Calibration in air (oxygen sensors only) The oxygen sensor can be accurately calibrated in air. To perform this type of calibration, the instrument must be set for calibration In air. In order to calibrate the sensor in air, you will need to extract it from its mounting or flow chamber, and wipe dry the sensor protection grille (if applicable).
