Commissioning CM14 6.5.1 Configuration of the relays The device has two relays with limit values that are either switched off or can be allocated to the input signal. The limit value is entered as a numerical value including the decimal position.
CM14 Calibration and adjustment 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 24
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.
CM14 Calibration and adjustment The calibration is not completed successfully or is canceled and is not valid. Possible reasons: • The sensor is old or contaminated. As a result, the permitted limit values for the slope and/or zero point are exceeded.
Maintenance CM14 Press "E" and select "yes" to confirm. 10. Remove the sensor from the measurement medium, flush with distilled water, dry it and place it back into the measurement medium. To calibrate the ORP sensors, you can also remove them from the medium and calibrate them in the laboratory.
