EQ1
The abbreviations used here have the following meaning:
ml: Total consumption, e.g. for pH Stat
S: Slope in ml/time (pH Stat)
EQ: Consumption at the equivalence point 1 and 2 in ml
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)
Factor 1 – 5 conversion factors
F1 - F5
"Weight", weighed-in quantity in g or volume in ml
W
After selecting a formula, please 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. 67).

EP1
EP2*T*M*F1/(W*F2)
(EP2-EP1)*T*M*F1/(W*F2)
(F3*EP2-EP1)*T*M*F1/(W*F2)
(F1/W) * EP1 *F2
((F1/W)*(EP2-EP1) * F3-F4)*F5
