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.
