The electrode has a short
circuit. 1. Check the Pt wires.
2. Activate the electrode check.
The endpoint is
reached too quickly. The dosing rate outside the
control range is too high. Define Titration rate = user and reduce the
dosing rate (Max. rate) (see Chapter 28.1.2,
page 261).
The titration times
with volumetric
titration are con-
stantly longer. With two-component
reagents the buffer
capacity of the solvent can
be exhausted. Replace the working medium.
