14. When the cell conditioning is complete add the standard. Remove the sample stopper and put the
correct amount of standard into the beaker with an applicable utensil. Make sure that all of the
standard is put into the center of the beaker and that none of it spills onto the walls of the beaker.
15. Put the sample stopper back into the sensor holder. Make sure that the sample stopper fits tightly
into the sensor holder.
16. Weigh the empty sample container and subtract this value from the weight of the standard in its
container (refer to step
13 ). The result is the exact weight of the sample analyzed. Write down
this value.
17. Push Start to start the moisture content analysis. Calibration data shows on the display.
Note: The moisture content analysis will start automatically after the addition of sample if the Injection
Autodetect parameter is set to Yes.
18. If the default stirring speed needs to be adjusted, push the up and down arrow keys to increase or
decrease the speed.
Note: Changing the default stirring speed can effect the measurement result.
19. Two options are available during the calibration 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 calibration 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.
20. When the calibration is complete, enter the exact weight of the sample analyzed (refer to step
16 ). If necessary, push the arrow keys to change the value shown on screen. Push Select to
accept the value.
21. When the calibration is complete, push the left and right arrow keys to see the different calibration
views.
22. 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
Get a sample measurement
Use this option to get sample measurements with one of the installed applications.
1. Make sure that the glass beaker, the sensor holder and all related parts are clean and dry. Put a
magnetic stir bar into the beaker.
2. Attach the beaker to the sensor holder. Make sure that the beaker fits tightly into the sensor
holder.
3. Read the related "Application Note" from the USB applications key for more instructions.
4. Fill the beaker with the applicable amount of solvent. Refer to the application note and Cell
management on page 25 to adapt the volume where applicable. Make sure that there is no
liquid spill. Make sure that the initial level is enough so that the sensor is correctly installed in the
sample. Do not put too much solvent in the beaker.
5. From the home screen, select the measurement application, then push Select .
