12. 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. Any adjustment only applies to
the current operation. The standard default stirring speed for the application is not changed.
13. The cell drift threshold, stability bar, sample temperature and measurement duration are shown at
the bottom of the display. The stability bar shows the stability of the signal and ranges in color
from red (unstable), through yellow, to green (stable). The cell drift value is shown in the middle of
the display. These messages can be displayed under the cell drift value:
Message
Excess of water
Excess of titrant
Risk of cell overflow The measurement cell is full and there is a risk of liquid spill. The
Note: The stability bar or these messages are displayed at the bottom of the display during the measurement
procedure.
14. Two options are available during the cell conditioning procedure:
Option Description
Stop Aborts the measurement and no results are calculated. If selected during the
Replicate Sample option, then all data in the series is lost.
Skip Stops the cell conditioning and goes directly to the next step in the procedure. Results
are then calculated from measurement data available before Skip is selected. Results
can be less accurate using this option.
15. Weigh the sample in its container and write down the result.
16. When the cell conditioning is complete add the sample. Remove the sample stopper and put the
correct amount of sample into the beaker with an applicable utensil. Make sure that all of the
sample is put into the center of the beaker and that none of it spills onto the walls of the beaker.
17. Put the sample stopper back into the sensor holder. Make sure that the sample stopper fits tightly
into the sensor holder.
18. Weigh the empty sample container and subtract this value from the weight of the sample in its
container (refer to step 15). The result is the exact weight of the sample analyzed. Write down
this value.
19. Push Start to start the moisture content analysis. Measurement 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.
20. 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.
21. Two options are available during the measurement procedure:
Option Description
Stop Aborts the measurement and no results are calculated. If selected during the
Replicate Sample option, then all data in the series is lost.
Skip Stops the measurement and goes directly to the next step in the procedure. Results
are then calculated from measurement data available before Skip is selected. Results
can be less accurate using this option.
