Sonics VCF1500HV - Manual (Page 9)

8.
Depress the POWER switch all the way to energize the unit. The switch will
illuminate.
9.
Depress the TEST switch and check the power monitor. The power reading should be
less than 20%.
NOTE
The probe within the High Volume Flow Cell is tuned to vibrate at a specific
frequency. If the resonant frequency of the probe has changed, due to cavitation
erosion or fracturing, a minimum reading will not be obtained. If an overload
condition exits, or if minimum reading cannot be obtained (less than 20%)
disconnect the converter and repeat the above procedure to determine which
component might be defective. If minimum reading is obtained using the
converter without the probe, the probe is defective and should be changed.
A loose probe will usually generate a loud piercing sound.
Refer to Section III if an overload condition exists.
NOTE
Since the amplitude required is application dependent and subject to the
volume and composition of the sample, it is recommended that the
amplitude be first set at mid-range, then empirically determined and
optimized while the sample is being processed.
CAUTION
Your Ultrasonic Processor features automatic tuning and does not require any manual
adjustments. DO NOT ATTEMPT TO TUNE MANUALLY. Ignoring this caution will
cause the power supply to fail.
