1.4 Working with several dosing units
Here you will learn how to work with several dosing units.
Several dosing units can be used
•
if a working station will be permanently installed for spe-
cific analysis, e.g. having a dosing unit specially prepared
for Karl Fisher titrations
•
if several titrations are being carried out in the same
sample. The linking of various methods is possible with
TIP (
Ti
tration
P
rocedure), see page 81 of the Instructions
for Use.
•
for addition of auxiliary solutions
Selection of the dosing unit in the titration method
Selection of the dosing unit in the titration method
The dosing unit is selected in the method. The method runs
always with the selected dosing unit.
Connect the dosing unit D1 and arm it with an Exchange Unit
(the Dosino with a Dosing Unit, resp.).
<user meth>
<enter>
<select>, <enter>
n x <parameters>
m x <enter>
<select>
<enter>
2 x <QUIT>
<START>
Recall the method "HCl" from the user memory: Press the key
<user meth>. In the display appears ">recall method". Press
<enter>.
Select the method name "HCl" with the key <select> and re-
call the method with <enter>.
The dosing unit of this method is D0, i.e. the Titrino itself.
To change the dosing unit, press the key <parameters> re-
peatedly until ">titration parameters" appears in the display.
Press <enter> until "dos.element:" appears. With <select>
you can choose between
internal D0:
Dosing unit of the Titrino
external D1: externally connected dosing unit 1, or 2, resp.
Choose e.g. "external D1", confirm the input with <enter> and
quit with the key <QUIT>.
The display shows now e.g. "DET pH D1 HCl". D1
means, that in this method the external dosing unit D1 is be-
ing used.
Start the method.
After the titration "D1a" appears in the display. "a" means
"active", the dosing unit D1 is now active.
