Using Soniclean's Ultrasonic Performance Meter (UPM)
Test Procedure
- Before proceeding with the test, turn the ultrasonic cleaner on for a few minutes to degas.
- Lower the UPM probe into the tank so the probe head is completely submerged.
- With the probe held still, press the central pushbutton on the meter unit. Performance measurements will be made and displayed on the bargraph continuously until the button is released.
- Satisfactory cavitation is being achieved if the UPM indicates a reading between 7 and 10.
