Dosing device

Dosing device

[ internal D0 ]

(Titrino)

external D1, external D2

(736, 751, 799)

Selection of the dosing device to be used for the dosing. All the dosing de-
vice connections (MSB) are displayed which are possible with the selected

device type.

Solution

24 characters, solution name, [ not defined ]

Input or selection of the solution defined in the solution table. Additionally,

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 correct solution

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 solution will be checked as well as the GLP
test interval for the buret. If

not defined

is selected no tests will be carried

out.

Tandem dosing

on, [ off ]

(only Titrando)

If this option is enabled, the dosing is carried out without interruption with a
combination of two dosing devices so that the second dosing device is

dosing while the first one is being filled and vice versa (see STAT pH - Gen-
eral/Hardware
).

Dosing device

1 ... [ 2 ] ... 4

(835, 836, 842)

1 ... [ 2 ] ... 3

(855)

Selection of the second dosing device (exchange or dosing unit) to be

used for the dosing if the first dosing device is not available.

Solution

24 characters, solution name, [ not defined ]

(only Titrando)

Input or selection of the solution defined in the solution table. Additionally,

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 correct solution
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. If

not defined

is selected no tests will be carried out.

Filling rate

0.01 ... 166.00 mL/min, [ maximum ]

(only Titrando)

Speed with which the dosing cylinder of the second dosing device is to be
refilled. The maximum filling rate depends on the cylinder volume of the ex-
change unit or dosing unit used. If the entered filling rate is too high for the
selected dosing device then during dosing it will automatically be reduced

to the largest possible value (see STAT pH - General/Hardware).

Sensor

Measuring input

[ 1 ] ... 2

(Titrando)

[ 1 ]

(855)

[ 1 ] ... 2, diff.

(Titrino)

Selection of the measuring input to which the sensor is connected.

Sensor

Sensor name, [ pH electrode ]

Selection of the pH sensor from the list of sensors defined in the sensor ta-
ble. The calibration data for the sensor will be adopted for the determina-
tion.
