Problem Cause Remedy
The induction time
is not evaluated
automatically,
although a signifi-
cant break point can
be noticed in the
curve. The Evaluate induction
time option is deactivated
in the method. Activate the evaluation of the induction time in
the method.
The Evaluation suppres-
sion option preventing the
evaluation of the curve in
the corresponding time
period is defined in the
method. Deactivate the corresponding option in the
method.
Automatic detection of the
induction time is not yet
possible. Keep the determination running until the
induction time is automatically found.
The curve progression is
too flat, with the result
that automatic detection
of the induction time is not
possible. ￭ Reduce the Evaluation sensitivity
method parameter.
￭ Evaluate the curves manually using tan-
gents.
An inappropriately high
value was used in the
method for the Evalua-
tion sensitivity. This value
makes a curve evaluation
impossible. Enter a lower value (e.g. 1.0) for the Evalua-
tion sensitivity option in the method.
The measurement
aborts without an
endpoint being
found. The measurement has been
stopped manually. Keep the measurement running until the end-
point is automatically found.
A time or conductivity
defined as a stop criterion
in the method is reached
before the endpoint. ￭ Activate the Stop once all the criteria
have been fulfilled option in the method.
￭ Increase the value for time or conductivity.
￭ Deactivate time or conductivity as stop cri-
terion.
