6.1 Get a sample measurement

Standard operations
Multiple hazards. Only qualified personnel must conduct the tasks described in this
section of the document.
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the
personal protective equipment appropriate to the chemicals that are handled. Refer to the
current safety data sheets (MSDS/SDS) for safety protocols.
Personal injury hazard. Never use the instrument without the syringe protection cover in place.
Chemical exposure hazard. Never remove the stir bar from the beaker before the end of a titration.
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
on page 26. 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 main menu, select the measurement application, then push Start.
Application information shows on the display.
6. If necessary, select an icon for more information or to change some data.
7. Make sure that the icon at the bottom of the display
instructions that show on the display adjacent to this icon. Make sure that the tubes
and sensor are correctly aligned.
8. Push Start to start the cell conditioning. Measurement data shows on the display.
9. 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.
10. If the options are available during the measurement procedure, push Skip to ignore
the current step or push Stop to abort the measurement.
11. Weigh the sample in its container and write down the result.
12. 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.
13. Put the sample stopper back into the sensor holder. Make sure that the sample
stopper fits tightly into the sensor holder.
