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

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
calibration procedure.
12. 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.
13. Weigh the standard in its container and write down the result.
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.
