10.2.5.1 Calibration presets
The default settings for calibration are stored permanently in this device.
Changing these settings can only be done by Ecolab.
In the calibration presets, the calibration routines are made available in the settings.
Non-approved calibration routines are not visible in the calibration menu.
More calibration presets are explained in the following table.

Explanation
Allow calibration of the relative cell
constant?
allow calibration of the temperature
coefficient?
Allow calibration of a temperature
coefficient curve?
Preset reference conductivity
Temperature input for automatic
temperature measurement at the
measuring point during calibration.
The conductivity of a solution at the
reference temperature and operating
temperature is read during the
calibration process. This results in two
pairs of values (temperature /
conductivity). These pairs of values
form the basis for the calculation of the
temperature coefficient.
The working temperature must differ by
at least 5°C from the reference
temperature.
Explanation
The starting and final temperatures of
the range in which a temperature
coefficient curve should be created.
The starting temperature must be at
least 20°C lower than the final
temperature. The reference
temperature of the measurement input
must lie between the start and final
temperature, and be at least 2°C away
from the start or final temperature.
