Calculate with
EP no. End point number (1 to Number of EP) for which the volume will
be used to calculate the result. Depending on the option selected for
Results by cumulate or difference, this will be the volume delivered
from the titration start to the end point no. "n" or the volume delivered
between the end points no. “n-1” and “n”.

Calculate with
IP no. Inflection point number (1 to Number of IP) for which the volume
will be used to calculate the result. Depending on the option selected
for Results by cumulate or difference, this will be the volume delivered
from the titration start to inflection point no. "n" or the volume
delivered between the inflection points no. “n-1” and “n”.
