4. Calibration information shows on the display. If necessary, select an icon for more information or
to change some data.
Option Description
Information Shows more information about the calibration.
Operator Changes the operator ID. Select from a list of applicable operators.
5. Fill a beaker with the recommended standard amount that shows on the display. If necessary,
add more of the solvent specified in the application note until the sensor is correctly installed in
the sample.
6. Carefully put a magnetic stir bar into the beaker. Make sure there is no liquid spill.
7. Attach the beaker to the sensor holder.
8. Make sure that the icon at the bottom of the display
show on the display adjacent to this icon. Refer to
that the tubes and sensor are correctly aligned.
9. Push Start to start the calibration. Calibration data shows on the display.
10. If the default stirring speed needs to be adjusted, push the up and down arrow keys to increase or
decrease the speed.
Note: This adjustment only applies to the current operation. The standard default stirring speed for the
application is not changed.
11. Two options are available during the procedure:
Option Description
Stop Aborts the calibration and no results are calculated. If selected during the Replicate
Sample option, then all data in the series is lost.
Skip Stops the current operation and goes directly to the next step in the procedure. Results
are then calculated from calibration data available before Skip is selected. Results can
be less accurate using this option.
12. Push Reject or Continue.
Option Description
Reject Rejects the calibration. Select Cancel to go back to the result display or Confirm to
reject the calibration. If this is the first calibration, select Confirm to reject the
calibration and use the default or previous calibration values. If this is a Replicate
Standard calibration, select Confirm to reject only the current calibration in the
series.
Continue Select from one of these options:
• Replicate Standard: Do the calibration again using the same standard
• Save & Exit: Keep the calibration results and exit the calibration procedure
• Reject & Exit: Reject the calibration results and use the default or previous
calibration values, and exit the calibration procedure
7.1.3 Auto leveling calibration
This option is only available when at least one installed application contains an auto leveling
calibration method. The calibration makes sure that the sample volume in the measurement cell is
the same before each titration. An external pump must be installed for this procedure to extract
sample from the beaker.
Refer to the Full User Manual, which is available as a download from our website.
7.2 Get a sample measurement
Use this option to get sample measurements with one of the installed applications.
