Range available:
-9.000 pH to +23.000 pH or -2000.0 mV to +2000.0 mV
End point delay Time during which the electrode signal is monitored after an end point
has been reached. If the electrode signal swings back, the burette
adds extra titrant to reach the end point and the count down of the
End point delay is repeated.

End point
method For this method, the user enters one or several pH/mV values, corre-
sponding to the end points to be found during the titration.
Up to 2 end points can be determined per method.
The titration is carried out using the continuous addition technique.
The speed of addition is adjusted with respect to the distance which
separates the end point from the slope of the titration curve and the
method parameters entered by the user.
