4.6.3.1 Calculation Formula

The appropriate calculation formula is selected on the Formula selection submenu (Fig. 79).
Fig. 79
The following calculation formulae are available for automatic titration mode:
Formula
EP
(EP-B)*T*M*F1/(W*F2)
(W*F2)/(EP-B)*M*F1)
The abbreviations used here have the following meaning
EP: Consumption at the end point in ml
B: Blank value in ml. Mostly determined by way of titration
T: Titer of the titration solution (e.g. 0.09986)
M: Mol; mol- or equivalence weight of the sample (e.g. NaCl 58.44)
F1 - F5 Factor 1 - 5 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 - F5 can be entered or read from a global memory
(Fig. 80).
