Maintenance

9.1

Cleaning the Measuring Cell

Make sure to clean the measuring cell before storing the instrument. Depending on
the application, also cleaning after each measurement may be required.
• Fill the cleaning agent using the built-in pump or a plastic syringe.
• Repeatedly flush cleaning agent through the complete measuring system.
9.2

Cleaning the Built-in Pump

Clean the built-in pump in regular intervals depending on the application. If you
measure aggressive samples, e.g. battery acid, clean the built-in pump more
frequently.
• To clean the built-in pump, open the pump lock and remove the pump.
• Rinse the pump with tap water moving the piston up and down.
• Dry the pump using a lint-free cloth.
• Re-attach the pump and close the pump lock.
