4.3 Calibration
4.3.1 Temperature compensation
There are three basic options for temperature compensation within the submenu probe in the
cell calibration menu:
•
automatic:
automatic:
automatic:
automatic: the signal converter will automatically compensate temperature influences using
the information of a Pt1000 temperature sensor.
•
manual:
manual:
manual:
manual: the signal converter will compensate temperature influences using a manually
entered value; this option only makes sense if the temperature of the measured medium is
quite constant.
•
off:
off:
off:
off: temperature compensation is disabled.
The menu for temperature within the menu process input (A or B) offers the following options:
•
Pt1000
Pt1000
Pt1000
Pt1000: choose this option if there is an external Pt1000 temperature sensor connected to the
signal converter.
•
manual
manual
manual
manual: choose this option if there is no internal or external temperature sensor connected
to the signal converter.
After starting-up the signal converter, the measuring screen appears. This is the standard
screen which is displayed automatically in the normal operating mode. If you are in this mode
and you want to choose the temperature compensation, you have to perform the following step:
CAUTION!
If you choose for measurement the temperature compensation "linear" than choose between
"automatic" or "manual" for the temperature compensation during calibration. If you choose for
measurement the temperature compensation "off" than choose also "off" for the temperature
compensation during calibration.
INFORMATION!
If you choose no compensation, the measured conductivity will most likely deviate from the
actual conductivity. The reason is that the conductivity of a specific medium varies depending on
the temperature of the medium.
