Description
The titration fails to determine the
equivalence point
The computed result is outside the accepted
limits
An equation variable is unknown (e.g. the
ordinate of the equivalence point is unknown
or the volume of the equivalence point is
unknown)
The applicable IntelliCAL electrode type for
the application is not connected.
The "Sensor name" set in the legacy adapter
settings does not agree with application
settings.
A titration or titrant calibration has been done
with an expired sensor calibration date
A titration has been done with an expired
titrant calibration date
The application data has been changed and
the application cannot be used
A system error causes the titration to stop
(e.g. a sensor has been disconnected or the
volume of reagent is too low)
The titration is stopped because the supplied
volume of reagent is more than the maximum
quantity
There is no description of the titrant
Possible solution
Refer to the application note for best practices
and do the titration again
Adjust the equivalence point detection value for
the application (refer to Change application
parameters on page 63)
Contact technical support
Refer to the application note for best practices
and do the titration again
Adjust the result minimum and maximum values
for the application (refer to
parameters on page 63)
Make sure that all the equation variables are
available (refer to the application note for the
equation description and values)
Connect the IntelliCAL electrode specified in the
application note.
Change the "Sensor name" setting in the legacy
adapter setting to agree with the sensor name
specified in the application note.
Calibrate the sensor and if necessary adjust the
calibration frequency (refer to the application
note for the recommended frequency)
Calibrate the titrant and if necessary adjust the
calibration frequency (refer to the application
note for the recommended frequency)
Remove the application or change the titrant to
a titrant that is already installed
Make sure that all the system elements are
connected and working correctly (refer to
Maintenance menu on page 42)
Refer to the application note for best practices
and do the titration again
Adjust the maximum volume stop point for the
application (refer to Change application
parameters on page 63)
Install the application again
Change application
