• Now prepare the sample, e.g. 30 µL water and start
the titration with
• Inject the sample and enter the weight in g:
If you have connected a balance, you can also back-
weigh the syringe.
The titration now runs.
The first line of the display shows the current volume. In
addition, a "↑" appears when dispensing is being per-
formed.
A "control bar" appears on the second line and shows
the control deviation of the current measured value
from the set endpoint.
On completion of the titration, the first line shows the
dispensed volume and the second the calculated titer.
If you have connected a printer, a report is also printed:
Perform another determination.
On completion of the titration, the mean value of the two determinations is calculated. The
report on the printer has the following appearance:
