    Calibration and adjustment CM14 Calibration and adjustment Definitions 7.1.1 Calibration (as per DIN 1319): Determining the relationship between the measured or expected value of the output variable and the corresponding true or correct value of the measured variable (input variable) for a measuring device under specified conditions.
  • Page 23 Calibrating with buffers with pH 7.0 and 4.0 is recommended for most applications. You use calibration buffers to perform two-point calibration. The quality buffers supplied by Endress+Hauser are certified and measured in an accredited laboratory. The accreditation (DAR registration number "DKD-K-52701") confirms that the actual values and the maximum deviations are correct and traceable.
