  • Page 51: Checking The Zero Calibration Data

    Information for accurate measurements Checking the zero calibration data On the Calibration Data Check screen, checks can be made of the amount of transmitted light for zero calibration and the number of days elapsed since the date of the last zero calibration. A check of the amount of transmitted light makes a comparison with the initial amount of transmitted light.

  • Page 52: Span Calibration

    Information for accurate measurements Span calibration Span calibration matches a measured value with an analyzed value. Since the span sensitivity of the light transmission method does not change, it is not intended to calibrate variations in sensitivity on the instrument side. A span coefficient is calculated to obtain a correlation between a measured value and an analyzed value, and to match a measured value to an analyzed value.
  • Page 53 Information for accurate measurements Span calibration procedure Span calibration enters a coefficient that was calculated beforehand. In a situation where an analysis can be made on site, it is possible to take a sample in a bucket on site and adjust the coefficient to the analyzed value. Put the converter in the span calibration mode.
