Xylem SI Analytics TitroLine 7500 KF trace Manual De Instrucciones página 99

If the reagents continue to run in from the storage bottle after the actual dosage process has ended, position the
bottle at lower level than the titration vessel. If the reagents continue to run in from the storage bottle between the
dosage process and the siphon off process, please wait a few seconds between the changes.
We recommend to remove the glass adaptor with the dosing and exhaust hose after adding the KF-anolyte
and to close the ground-in opening with the provided die glass stopper NS 14.5.
2.7 Filling the Titration Vessel
Fill the titration vessel approx. up to a half with anolyte that are suitable for the respective application using a
funnel (Module 1 and 3). You can even use the pump for modules 2 and 4. If you use a generator electrode with
diaphragm, it is necessary to fill an ampoule with catholyte into the generator electrode. Here, please use a
syringe with needle (Fig. 15).

2.8 Switch on Device, First Conditioning
Set the stirring speed at the TM 235/TM 235 KF. Please do not forget the magnetic stirring bar! Now switch on
the device. The mains switch is situated on the left at the back side of the TitroLine
starts conditioning immediately. If the anolyte is freshly filled in, the conditioning can last 10 - 20 minutes. In the
case of the generator electrode with diaphragm this can also take more than one hour. The drift display is then
> 1500 µg/min. When the drift has dropped below 10 µg/min, the TitroLine
measurements.
2.9 Combination with Accessories and Additional Devices
Connecting a printer
2.9.1
Printers with a USB interface are to be connected to one of the two USB-A interfaces.
These printers have to feature HP PCL emulation (3, 3 enhanced, 5, 5e).
So-called GDI printers cannot be used!
Alternatively the thermo-compact printer Seiko S445 can be connected.

Printer

USB storage devices, e.g. USB sticks

USB-Hub

USB barcode scanners
Connection of analytical balances
2.9.3
Analytical balances are to be connected to the RS232-2 using an appropriate cable.
