6.1.2 Cleaning interval
The cleaning interval is set with the measurement settings (see section 6.1
M
EASUREMENT SETTINGS (CONDUCTIVITY), page 24).
The calibration evaluation (sensor symbol) flashes when a valid calibration is
available for a measuring cell and the set cleaning interval has expired.
The flashing calibration evaluation reminds you to clean and calibrate the
measuring cell regularly (see section 5.2.3 D
ETERMINING THE CELL CONSTANT
(
CALIBRATION IN CONTROL STANDARD), page 19).
It is still possible to measure.
6.1.3 Selecting the temperature compensation
1. Open the calibration menu with <CAL>.
2. If necessary, select the Use tC setting with <CAL>.
3. Press <ENTER> or <CAL__> to confirm the selection of Use tC.
The set temperature compensation is displayed.
4. If necessary, change the setting of the temperature compensation with
<CAL>.
• nLF: Nonlinear temperature compensation
• Lin: Linear temperature compensation
If necessary, set the linear temperature coefficient with <><>.
• ----: No temperature compensation (temperature compensation
switched off)
5. If necessary, quit the setting of the temperature compensation with
<ENTER>.
The set temperature compensation is used.
Temperature compensation
The calculation of the temperature compensation is based on the preset refer-
ence temperature, 20 °C [Tref20] or 25 °C [Tref25].
