Ultrasonic cleaning
The "Ultrasonic cleaning" option is used for continuous cleaning of the flow-through
cuvette. It is not intended to clean cuvettes that are already dirty, or to replace manual
cleaning entirely. However, this system will increase the cleaning intervals dramatically.
To operate correctly, the use of a cuvette with an ultrasonic transducer is required. The
system transmits an ultrasonic frequency through a spring to a piezo transducer that is
joined to the base of the flow-through cuvette. The cuvette's detection system works only
in AUTO mode.
The system can detect the following error conditions:
• Incorrect cuvette installed
• Error has occurred in the transducer
• Transducer not making contact with the spring
If an error has occurred, the message "CLN" appears in the lower part of the display. The
alarms are set and 2mA is sent to the current output. The ultrasonic cleaning function is
switched on as standard. After a cuvette has been inserted, the message "Dry" appears for a
duration of 30 minutes in the lower part of the display. During this time, the desiccant
removes residual moisture from the ultrasonic transducer and no ultrasonic cleaning takes
place. At the same time, the error message "CLN" is reset and appears only after the 30
minutes have elapsed.
