5. 7 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 re-
quired for this. Four dosing units can be operated on one interface. Three
Dosimat Interfaces can be linked serially (cascaded, observe address, see
page 19). 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 Do-
simat or Dosino may be seriously damaged.
Always execute the 'DOS: XX : release' command before removing
the burette!
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 in-
strument.
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.
