Cleaning the Titrator surfaces
Periodically, the covers should be thoroughly cleaned using a mild soap solution on
a damp cloth. Always ensure that the accessory is disconnected from the power
supply before cleaning.
Never use excess liquid to clean the accessory and always avoid the electrical com-
ponents on the rear panel.
Always ensure that the accessory is completely dry before applying power.
Never use a solvent-based solution to clean the accessory as damage to the painted
surface may result.
Cleaning the sample and titrant path
To avoid cross-contamination of samples, the sample flow path should always be
kept scrupulously clean. Always flush the sample after each measurement session.
Note
Choose an appropriate cleaning fluid for the sample or titrants being used
(e.g. deionised water). Ensure that it will reliably clean the sample or
titrants used from the tubing.
Cleaning the sample tubing:
1.
Remove the sample container and replace with one full of cleaning fluid.
2.
Press the Clean button to begin the operation.
3.
The pump will circulate the cleaning fluid through the sample tubing until the
Clean button is pressed a second time. Use the pump and stirrer controls
(below) to adjust the pump and stirrer speeds during the cleaning.
4.
Perform the clean a few times to ensure the sample tubing is properly cleaned,
i.e. stop the clean operation, refresh the cleaning fluid and repeat. It is recom-
mended the clean procedure is performed three times to ensure adequate
cleanliness has been achieved.
5.
Once started, pressing Clean a second time will stop the operation.
Note
The larger the cleaning fluid container the more effective the cleaning
operation will be.
