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.
22. When the measurement is complete, enter the exact weight of the sample analyzed (refer to step
18 ). If necessary, push the arrow keys to change the value shown on screen. Push Select to
accept the value.
23. If the Cell standby option has been selected (refer to Cell standby on page 18), the standby
operation starts again automatically.
24. Push the arrow keys to see the different measurement views or push Next for the options that
follow:
Option Description
Replicate sample Use this option to start the same titration on the same sample. This is used to study the
repeatability by successively analyzing several parts of the same sample. At the end of
each measurement, a window shows the average value, the standard deviation and the
relative standard deviation.
New sample Use this option to start the same titration on a new sample. No standard deviation or
relative standard deviation measurements will be done.
Cell management Use this option to fill or empty the measurement cell using the pumps. Refer to Cell
management on page 25.
25. Push Exit to go back to the home screen.
Syringe verification
Use the syringe verification option to examine the syringe accuracy based on the ISO 8655 standard.
