2.8 Result calculations
Key
The key 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.

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
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
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.
