4.6 Dosimats and Dosinos Dosimats and Dosinos
685 Dosimats and 700 Dosinos can be connected as dosing units
to the "external bus" socket. An E-bus cable and a 729 Dosimat
Interface are required for this. Four dosing units can be operated
on one interface. Three Dosimat Interfaces can be linked serially
(cascaded, observe address, see page 23). This makes it possible
to connect 12 dosing units simultaneously to a 730 Sample
Changer and specifically address each of them with the 'DOS'
command.
Each Dosimat or Dosino may be equipped with various exchange
units. Before exchanging this units the stop-cock of the burette
must be driven to the exchange position. Otherwise the stop-cock
or the drive unit of the Dosimat or Dosino may be seriously dam-
aged.
Always execute the 'DOS: XX : release' command before re-
moving the exchange unit!
Dosimats and Dosinos can aliquot any volume of e.g. auxiliary
solutions desired up to 999 mL (in LEARN mode up to 5 burette
volumes). Filling the burette can be specifically initiated with both
instrument types ('DOS: XX : fill'). The Dosino burette is always
filled from the port 2 (rinse port) when the instrument is turned on.
The changer automatically recognizes the type of the connected
dosing instrument.
Further commands are available for the 700 Dosino so that the
many and varied abilities of these dosing units can be fully taken
advantage of.
