Error/Warning Description
There is no method to calibrate the titrant into the
application. If more than one application is installed,
there is no method to calibrate the titrant into all the
No titrant to calibrate
applications.
The titrant calibration has been deactivated (Basic or
Expert mode: Active = No)

Description
The titration is stopped because the supplied
volume of reagent is more than the maximum
quantity
The titration is stopped because the elapsed
time is more than the maximum time
When the maximum time setting completes
the titration, there is too much water in the
cell.
During all of the titration, the potentials of the
titration curve are in the "excess of titrant"
area.
There is no description of the titrant
No measurement can be done
The stirrer does not automatically start when
the measurement starts.
The red LED on the printer flashes to show
that the printer is in error mode. There is no
paper in the printer.
Syringe cannot deliver any reagent
Syringe cannot be filled with reagent
Syringe cannot calculate the delivered

Possible solution
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 59)
Refer to the application note for best practices
and do the titration again
Adjust the maximum time for the application
(refer to Change application parameters
on page 59)
Adjust the titrant concentration.
Add less sample.
Increase the Max time setting.
Examine the cell.
Examine the electrode.
Contact technical support
Install the application again
Make sure that the sensor is correctly
connected to the instrument
Disconnect the sensor and connect it again
Change the sensor if no measurement is
received using the Live Measure option (refer
to Other maintenance options
Make sure that the stirrer configuration is set
correctly. Identify if the applicable stirrer is
selected in the Settings>Options menu.
Replace the paper roll in the printer. Refer to
the printer documentation.

Possible solution
The titrant cannot be calibrated with the
current application. Refer to the related
application note to find if the titrant
calibration is available.
Activate the titrant calibration (Active = Yes)
