select ‘ Properties Run window’ . Under Process select
‘ Autorepeat determination’ . Close the window with .
 TitrIC pro II_pH calibration manual: Here the iAquatrode
is taken out of the titration vessel and placed into the
buffer solutions. Start this method only from tiamo
TM !
 TitrIC pro II_titer determination of HCl: This method is
used for the titer determination. It has to be used in
combination with the MagIC Net method
TitrIC pro
II_titer determination of HCl .
 TitrIC pro II_conductivity calibration: This method is used
for calibration of the conductivity sensor. It has to be
used in combination with the MagIC Net method
TitrIC
pro II_calibration conductivity .
Import: Click on Method at the left, then select under File /
Method manager… / Edit / Import… Import the methods
related to TitrIC pro II also from the MagIC Net CD. You will
find the methods in the folder example/TitrIC of the CD.
Note!
Alterations of these methods should only be carried out by a
person at the administrator level and who is thoroughly
familiar with tiamo
TM .
 Shut down tiamo TM
6.4. Setup of RS232 communication between
MagIC Net and tiamo TM
The communication, e.g. result transfer between MagIC Net
and tiamo
TM is done via RS232. MagIC Net is the master in
this setup. To establish the communication follow the steps
below:
Make sure MagIC Net and tiamo TM software are closed. If
the PC has two built-in RS232 ports you can connect the
RS232 cable (6.2134.040) directly between the two ports. If
the PC does not have the built-in RS232 ports please
connect two USB/RS232 Converters (6.2148.050) to two
USB ports. You can e.g. use the USB hubs of the IC
instrument, but it is recommendable to use the USB hubs of
your computer, as they are more powerful. Then connect
the two converters using the RS232 cable (6.2134.040). In
the Device Manager of your Windows operating system
check which two RS232 ports you are using.
Open the MagIC Net software. On the left click on
‘
Configuration’ , then in the devices window select
‘ Edit/New/Miscellaneous’ and choose the RS 232 device.
Keep the proposed Device name and enter a random serial
number. Go to the RS232 subsection and choose one of the
used RS232 ports. Click on ‘
Connect’ and confirm with .
Close the window with
Repeat the same steps in the tiamo TM software and choose
the second RS232 port.
7. Complete Analysis with TitrIC
As an example a short description of a complete analysis
with TitrIC pro II is described here.
The whole procedure is controlled by the MagIC Net
software which is the master software. In tiamo
TM , the
method TitrIC pro II is selected as a single determination.
Start the determination in an autorepeat mode. To set it into
autorepeat go to the Run window, right-mouse-click and
select ‘
Properties Run window’ . Under Process select
‘ Autorepeat determination’ . Close the window with .
Start the determination. Now tiamo TM is waiting for the start
signal from MagIC Net via RS232.
In the MagIC Net software select the method TitrIC pro II .
Enter the required sample position, sample identification etc.
into MagIC Net. For value 1 choose according to the list
below:
 Value 1 = 1 a complete analysis including titration and
ion chromatography
 Value 1 = 2 only an ion chromatography analysis (e.g.
a calibration)
 Value 1 = 3 only a titration analysis
Start the determination in MagIC Net. All sample liquid
handling is done by MagIC Net. At the right moment MagIC
Net communicates to tiamo
TM via RS232 to do the titration
analysis. Results are transferred back to MagIC Net and the
rinsing steps of the titration equipment by MagIC Net
initialized.
All data goes into the MagIC Net database and therefore
one report can be generated.
