Commands 409
Solution
24 characters, solution names, [ not defined ]
Input or selection of the titrant or solution defined in the solution table. Addi-
tionally, not defined can be selected. If intelligent exchange or dosing units
are used then a check will be made in the method sequence that the cor-
rect titrant is present in the connected dosing device and whether the type
of dosing device is correct. With non-intelligent exchange or dosing units
the cylinder volume is checked. At the start of the command the validity of
the titer and the expiry date of the selected titrant will be checked as well as
the GLP test interval for the buret. If
not defined is selected no tests will be
carried out.
Sensor
Measuring input
[ 1 ] ... 2 (only Titrando)
Selection of the measuring input to which the sensor is connected.
Sensor
Sensor name, [ Metal electrode ]
Selection of a sensor of type Metal electrode from the list of sensors defined
in the sensor table.
I(pol)
-125.0 ... [ 50.0 ] ... 125.0 µA (Titrando, in 2.5 µ A steps)
-127 ... [ 50 ] ... 127 µA (Titrino, in 1 µ A steps)
The polarization current is the current applied to the polarized electrode
during a voltametric measurement.
Electrode test
on, [ off ]
Switching on/off the electrode test for polarized electrodes. The electrode
test for polarized electrodes is carried out during the transition from an in-
active condition to a measuring condition.
Temperature measurement
Type of temperature measuring (only Titrando):
continuous
A temperature sensor must be connected. The temperature is measured
continuously.
[ automatic ]
If a temperature sensor is connected then the temperature will be meas-
ured continuously. Otherwise the manually entered
Temperature (tab Titra-
tion parameters ) will used.
off
The temperature will not be measured. The Temperature (see Titration pa-
rameters) which has been entered manually will be used.
Stirrer
Stirrer
[ 1 ] ... 4, off (only Titrando)
Selection of the stirrer. off means that no stirrer will be used.
Stirring rate
-15 ... [ 8 ] ... 15 (only Titrando)
Setting the stirrer speed. The direction in which stirring takes place changes
as the sign in front of the stirrer speed changes.
Switch off automatically
[ on ], off (only Titrando)
If this option is enabled, the stirrer will be switched off automatically when
the command is finished.
Switch on/off automatically
[ on ], off only 751, 785, 798, 799)
