￭ 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 mea-
sured continuously. Otherwise, the calibration temperature entered
manually will be used.
off
The temperature will not be measured. The calibration temperature
entered manually is used. The temperature is requested after the start,
except the determination is carried out with a Sample Processor.
29.10.6 Stirrer
The parameters for the stirrer are edited under [Stirrer].
Stirrer
Selection of the MSB connector the stirrer is connected to. Every MSB
connector will always be displayed.
Selection 1 | 2 | 3 | 4 | off
Default value 1
off
No stirrer will be used.
Stirring rate
Setting the stirring rate. It can be set in steps of –15 to +15. The default
setting 8 corresponds to 1000 rpm. The formula for calculating the rota-
tional speed is specified in chapter 32.4, page 494. The optimum stirring
rate can be tested in the manual control.
The algebraic sign of the stirring rate changes the direction in which the
stirring is done. When the stirrer is viewed from above, this means:
￭ "+": counterclockwise rotation
