3. Operation
The UPM is simple to use. The probe is lowered into the
ultrasonic cleaner's tank and the ultrasonics are
activated. The probe's head should be completely
submerged. Pressing the central pushbutton on the
meter unit will turn the UPM on. Performance
measurements will be made on a continous basis until the
button is released, at which point the unit will turn off. If
the optional DC power adapter is being used the UPM will
remain on until the DC power supply is turned off or
disconnected.
Satisfactory cavitation is indicated when the bar graph
displays any green segments, corresponding to a
performance measurement between 7 and 10.
It is important to note that disturbed water inhibits
cavitation. For this reason the probe should remain
stationary in the tank and the liquid allowed to settle
before a reading is taken. Furthermore, to facilitate the
comparison of measurements, readings should be taken
with the probe submerged to a consistent depth.
