Maintenance and repair
6.1
Maintenance
SONOPULS homogenisers are maintenance-free.
Aside from the process-dependent cavitation erosion on the sound-emitting surface of the probes,
no other homogeniser parts are subject to wear. Worn out or faulty probes can be replaced
following the instructions in chapters 4.3.1 to 4.4.
The devices are calibrated at the time of delivery. A control of the calibration is only required after
repairs, and will only be conducted by the manufacturer.
6.2
Functional checks
See also chapter 3.2.4 for description and operation.
6.2.1
Testing the ultrasonic transducer (probe check) – Error 011
The test is preferably conducted while the probe is acoustically coupled, i.e. the probe should be
immersed in the sonicating medium.

The HF or ultrasound frequency depends on the probe, and the actual value may vary from the
example presented here. After successful completion, the monitor display switches back to stand-
by mode. Otherwise, an error message appears again.
6.2.2
Conducting a frequency scan (scan frequency) – Error 002/011/012
The conditions for execution are similar to those for conducting checks with the "probe check"
function, see chapter 3.2.4.
