Calibration Presets - ECOLAB Versatronic Betriebsanleitung

10.2.4.1 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 released, which should be
accessible for the respective calibration. 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?
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.
