900 Touch Control
Electrode check
on | off (Default value: off)
For the following electrodes, an electrode check can be carried out:
pH electrodes
Metal electrodes
Ion-selective electrodes
A check is made that the electrode is properly connected and that no
short-circuit is present. The electrode check is carried out when this com-
mand is started. Note that this electrode check has nothing to do with the
electrode test (command ELT).
Temp. measurement
Type of temperature measurement.
Selection continuous | automatic | off
Default value automatic
continuous
A temperature sensor must be connected. The temperature is mea-
sured continuously.
automatic
If a temperature sensor is connected then the temperature will be
measured continuously. Otherwise, the temperature entered manually
will be used (see dialog of the titration and measuring parameters).
off
The temperature will not be measured. The temperature entered man-
ually is used (see dialog of the titration and measuring parameters).
29.4.9 Dosing device
The parameters for the dosing device are edited under [Dosing device].
Dosing device
Selection of the MSB connector the dosing device is connected to. Every
MSB connector will always be displayed.
Selection 1 | 2 | 3 | 4
Default value 1
Titrant
Selection of the titrant from the titrant list. We recommend always select-
ing the titrant. This ensures that the correct data (titer, concentration, etc.)
is always used for the calculation. Titrants are defined under Sys-
tem Titrants. You can also enter a name which is not contained in the
titrant list. When a determination is started there is a check whether the
solution is contained in the list.
