Visual check
Power consumption
Aluminum sheet test

After degassing there should be waves visible on the surface of
the cleaning bath.
There must not be any streamers on the floor of the cleaning
tank (floor cavitation).
The power consumption of the ultrasound can be measured
with a standard wattmeter (observe measuring range).
Compare the measured values with the values given in the
table in section 4.4 Technical Details.
For this test the heating remains switched off.
There is a simple method to check the ultrasonic effect in the
cleaning liquid: cavitation check with an aluminum sheet.
Cut a piece of the size and shape of the transducer tank from a
roll of a standard aluminum foil.
Put this sheet vertically into the liquid for 1 minute with the
ultrasound switched on. The ultrasound will tear pieces out of
the sheet. The size of the torn holes indicates the zones of
different cleaning intensity in the cleaning tank. It is normal that
the number of holes is bigger around the transducer elements.
