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 26), 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 37.
25. Push Exit to go back to the home screen.
7.3 Get a sample measurement (cell standby option selected)
Use this option to get sample measurements with one of the installed applications, with
the cell standby option (refer to
Cell standby on page 26) selected.
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 37 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.
