2.8 Result calculations
Key <CALC DATA>
The key <CALC DATA> is used to enter the values for
the calculations. The data of this key are method
specific to a sample (sample size and identification) or
to a mode (titer, factor, blank, mean value) and the drift
correction applies to all modes. On exit the result is
always recalculated. Values marked with "cond." are
accessible during the conditioning. "**titr." means that
these values can be changed during the titration. They
influence the ongoing determination.

statistics:

The display texts of the Titrino are shown to the left.

Assignments for the result calculation
Sample size (6-digit number ±X.XXXXX)
Entry using keypad, via balance.
Sample sizes that are inquired automatically in the
titration sequence can be viewed and modified with the
<CALC DATA> key. For calculation the absolute
sample size is used (negative signs that appear, e.g. in
backweighing are ignored).
No inquiry of sample size in the "BLANK" mode.
Sample identification (up to 8 ASCII characters)
Entry using keypad, via balance.
Sample sizes that are inquired automatically in the
titration sequence can be viewed and modified with the
<CALC DATA> key.
No inquiry of sample size in the "BLANK" mode.
Titer(0.0...99.9991 mg/mL)
The titer is written in automatically from the titer
determination modes.
Request only in the "KFT" mode.
Factor ( ± 1000000)
in the numerator of the formula. Entries for factors with
different units for results and sample size, see page
33f.
