Formula characters
Meaning
EP1, EP2, EQ1, EQ2
Results from a titration like e.g. EQ1, EQ2 etc
F1 –F10
Values which can contain fixed, manual, global
memory or results of other formulas.
T
Titer of the titration burettes
W
Weight sample
B
Blanc value
D
Density
S
Slope in ml/s of a pH stat-application
EV
End- or total volume of a titration. Is needed if you
want to calculate the difference between an
equivalence point EQ or end point EP to the total
(end) volume
M
Molecular mass or equivalent weight
M01-Mxx
Global memories
R1-2
Result of a formula calculated previously in the
application.
If a global memory Mxx is used, which is not created, this is created automatically and assigned the default
value 1.
Only results of the preceding formulas can be used. This is checked in the syntax check.
