3.24.2 Dosing

In the dialog Manual control/Dosing you can dose manually and

prepare or empty dosing devices. You can also check which dosing

devices are connected and which exchange or dosing units are

attached.

Select the [Dosing] function in the Manual control dialog. If

several dosing devices are connected to a control device then the

dialog for selecting a dosing device will be opened. If only one

dosing device is connected then the properties of this dosing

device will be shown directly:

For every dosing device the connection (MSB 1 to 4) and the type

are shown on the button. With type 8XX dosing devices with an

intelligent exchange unit or dosing unit the titrant will be shown to the

right. With type 6XX or 7XX dosing devices only the cylinder volume of

the exchange or dosing unit will be shown. If the exchange or dosing

unit is not (correctly) attached to a connected dosing device then "---"

will be shown. If a dosing device is busy with the determination

sequence then this will be indicated accordingly with "Manual busy".
With [All dosing devices] you can carry out the commands Fill,

Prepare and Empty for several dosing devices of a control device at

the same time.

Select the dosing device to be controlled manually.
