The atmospheric correction system of this instrument corrects automatically when the correction value is set. 15°C/59°F, and 1013.25hPa / 760mmHg / 29.9 inHg is as a standard value for 0ppm in this instrument.

Press the [ ] key.
  • Page 94 7 SETTING ATMOSPHERIC CORRECTION ● How to Set the Atmospheric Correction Value Directly Measure the temperature and air pressure to find atmospheric correction value(PPM) from the chart or correction formula. Turn the power switch on. Press the [ ] key. Press the [Prism constant value, Atmospheric correction] icon.
  • Page 95 7 SETTING ATMOSPHERIC CORRECTION Atmospheric Correction Chart (For your reference) The atmospheric correction value is obtained easily with the atmospheric correction chart. Find the measured temperature in horizontal, and pressure in vertical on the chart. Read the value from the diagonal line, which represents the required atmospheric correction value. Example: The measured temperature is +26°C The measured pressure is 1013 hPa...
