4.6.1.1 Calculation Formula
The appropriate calculation formula is selected on the Formula selection submenu (Fig. 42).
Fig. 42
The following calculation formulae are available for automatic titration mode:
Formula
µg
(µg-B)*M*F1/(W*F2)
µg*M*F1/(W*F2)
The abbreviations used here have the following meaning
µg
: absolute water content
B: Blank value in µg. Mostly determined by way of titration
M: Mol; mol- or equivalence weight of the sample
F1 – F2
Factor 1 - 2 conversion factors
"Weight", weighed-in quantity in g or volume in ml
W
Confirm your selection with <ENTER>/<OK>.
The values for the blank value, the titers and factors F1 – F2 can be entered or read from a global memory
(Fig. 43).
