8.11 Dosing commands
The dosing commands allow various auxiliary reagents to be added from
different dosing devices during complex method runs.
ADD_A
Adding an absolute volume
The ADD_A command allows a preset volume of an auxiliary reagent to be
added at any time during a method run.

ADD_A Reagent Dos. drive A1
Concentr. Dos. rate max mL/min
Volume 0.0 mL Fill. rate max mL/min
Reagent
Reagent name
13 characters
If a name is entered here the automatic reagent check can
be used.
At the start of the method a check is made as to whether a
different entry for the current occupancy of the addressed
dosing device has been given under 'Devices & Man-
ual Control'
( <MAN CONTROL> key). If these do not
coincide an error message is displayed.
No entry in the 'Reagent' field (or on the 'Devices & ...
'
page) prevents an automatic reagent check.
Dos. drive
Dosing device address
(A1…A4, B1…B4, C1…C4)
The connection sockets Dos. A1…Dos. A4 on the rear
panel of the instrument have the addresses A1…A4.
Further dosing devices connected to the 'External Bus'
with the help of a Dosimat interface 729 receive the ad-
dresses
B1…B4 (Dosimat interface 1, EBus address 1) or
C1…C4 (Dosimat interface 2, EBus address 2).
Concentr.
Concentration of auxiliary reagent
(numerical | 5 characters)
Two fields for the input of the concentration of the reagent
solution and concentration units. These fields are also used
for reagent checking (see above) and are compared with
the entries in the dialog window 'Devices & Manual
Control
' at the start of a method.
