The following settings can be made for each of the two limit values: assignment, limit, hysteresis, switching behavior, delay and fault mode.
  • Page 22 Commissioning CM14 6.4.3 Temperature compensation The conductivity of a fluid is highly temperature-dependent, as the movement of the ions and the number of dissociated molecules is temperature-dependent. To compare measured values, they have to be converted to a defined temperature. The reference temperature is 25 °C (77 °F).
  • Page 23 CM14 Commissioning A0008939 Compensation for natural water The compensation for natural water is activated using the setting Extended setup É Input É Temp. comp. = Water ISO 7888. For temperature compensation in natural water, a nonlinear function to ISO 7888 is stored.
  • Page 24 Commissioning CM14 Limit values for pharmaceutical waters as per United States Pharmacopeia (USP) and European Pharmacopoeia (EP) (only for conductive sensors) For conductive sensors, the transmitter has functions for monitoring "Water for Injection" (WFI), "Highly Purified Water" (HPW) and "Purified Water" (PW) according to the United States Pharmacopeia (USP) Part 645 and European Pharmacopoeia (EP) standards.

  • Page 25: Device Diagnostics (Diagnostics Menu)

    CM14 Commissioning The measurement is carried out in the following steps: • The transmitter measures the uncompensated conductivity and the water temperature. • If the temperature is between two table entries, the limit value for conductivity is determined by interpolation from the two neighboring points.

  • Page 26: Calibration (Calibration Menu)

    This is particularly important in the pharmaceutical industry, where traceability of the calibration to internationally recognized standards is mandatory. To calibrate its test equipment, Endress+Hauser uses the SRM (Special Reference Material) of the US government agency NIST (National Institute of Standards and Technology).

    CM14 Maintenance Setting: In the menus, navigate to Extended Setup É Input É T.comp.cal: Select "off". This switches off the temperature compensation for the calibration. The new cell constant is calculated from the new conductivity reference solution. The method for cell constant calibration is the same for conductive and inductive conductivity.
