20.000

Measured value (measuring mode U, Ipol):
Input range

–2,000.0 - 2,000.0 mV

Default value

2,000.0 mV

Measured value (measuring mode Upol):
Input range

Volume:
Input range

0.00000 - 9,999.99 mL

Default value

9,999.99 mL

EP criterion

The equivalence point criterion found (ERC = Equivalence point Recogni-
tion Criterion) is compared with this value. Equivalence points whose ERC
is less than the value defined here will be ignored.

Input range

0 - 200

Default value

5

EP recognition

This parameter allows you to filter out only the equivalence points that are
being sought.

Selection

first | greatest | last | ascending | descending

Default value

first

first
Only the first equivalence point will be recognized.
greatest
Only the equivalence point with the greatest ERC value, i.e. the steep-
est jump, will be recognized.
last
Only the last equivalence point will be recognized.
ascending
Only equivalence points with a positive slope of the titration curve will
be recognized.
descending
Only equivalence points with a negative slope of the titration curve will
be recognized.

Only one equivalence point will be recognized in a window. The number-
ing of the equivalence points (EP) is defined by the numbering of the win-
