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
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.
Get a sample measurement
Use this option to get sample measurements with one of the installed applications.
1. From the home screen, select the measurement application, then push Select. Application
information shows on the display.
2. Read the related "Application Note" from the USB applications key for more instructions.
3. If necessary, select an icon for more information or to change some data.
Option Description
Information Shows more information about the application.
Operator Changes the operator ID. Select from a list of applicable operators.
Sample Sample Name: Change the specified name of the sample.
Type: Push the left and right arrow keys and select the sample type (Sample, QC or Define
blank) to be used for the measurement. If Define blank has been selected before, two more
sample types are available (QC with blank and Sample with blank).
4. Fill a beaker with the recommended sample 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.
5. Carefully put a magnetic stir bar into the beaker. Make sure there is no liquid spill.
6. Attach the beaker to the sensor holder.
