10. The titration measurement starts after the leveling procedure completes. 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 calibration is not changed.
11. Two options are available during the calibration procedure:
Option Description
Stop Aborts the calibration and no results are calculated. If selected during a Replicate
Standard calibration, then all data in the series is lost.
Skip Stops the leveling operation and goes directly to the next step in the procedure.
Results are then calculated from the data available before Skip is selected.
12. When the calibration is complete, push the left and right arrow keys to see the
different measurement views. The result of the titration is the calculated volume of
sample.
13. 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 sample
• 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
14. If the calibration is successful, the calculated volume of sample is kept in the
application parameters. This value is shown in the measurement start view for that
application and is used in the next titration calculations of the application.
When this application is installed (refer to
prepare one or more measurement samples.
Note: If the PC software is installed (refer to
AS1000 sample changer is installed, sample preparation can be done with or without leveling. But if
the sample preparation is done without the software and sample changer, then leveling must be
deactivated (Active = No). It is recommended to read the related "Application Note" from the USB
applications key for more instructions.
1. From the home screen, select the sample preparation application, then push Select.
2. Make sure that the reagent used to prepare the sample is installed with the correct
pump.
Note: The application parameters can be changed in basic or expert mode. Refer to
the application settings
3. Obey the instructions on the display.
4. Push Next to prepare more samples or Exit to go back to the home screen.
Use this option to get sample measurements with one of the installed applications.
