354 Method
Device type
Device types, [ Titrando ]
Display or selection of the device type. If a device is selected under Device
name , this parameter is not editable any more. The device type belonging to
the selected device is displayed instead.
If the option
not defined is selected as Device name , all device types being
able to execute the command can be selected independently from the de-
vices in the device table.
Dosing device
Dosing device
[ 1 ] ... 4 (808, 809, 835, 836, 857)
[ 1 ] ... 3 (855)
[ internal D0 ] (Titrino)
external D1, external D2 (only 736, 751, 758, 799)
Selection of the number of the dosing device (dosing or exchange unit) to
be used for the dosing.
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 808, 809, 835, 836, 857)
[ 1 ] (only 855)
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 ... [ 5.0 ] ... 125.0 µA (Titrando, in 2.5 µ A steps)
-127 ... [ 5 ] ... 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.
