temperature coefficient for each interval. This requires installation of a temperature sensor that the de-
vice can use to sense the temperature of the sample solution. The series of temperature values consists
of 7 values in total:
•
"Starting temperature and end temperature of the TC-curve" (see "Calibrating the temperature co-
efficient curve (TC-curve)", page 47)
• Reference temp. (see chapter 13.3.1 "CR input (resistivity conductivity)", page 71)
• 4 additional temperature values between the "starting temperature and end temperature of the TC-
curve"
The "end temperature of the TC-curve" be at least 20 °C higher than the "starting temperature of the TC-
curve". The two values are requested at the start of the TC-curve calibration and must be entered by the
user.
The reference temperature must lie between the "starting temperature and end temperature of the TC-
curve" and must differ from the starting temperature and end temperature by at least 1 °C. It is set in the
configuration of the Ci conductivity input.
The intervals between the starting, reference-and end temperature are automatically divided into 6 inter-
vals by the device. The remaining 4 temperatures are determined in this way.
