1. Using the fittings on top of the converter, circulate dry compressed air through the
converter to cool the converter.
2. Depress the START key.
3. With the liquid flowing through the High Volume Flow Cell, adjust the pressure
within the cell and the amplitude so as to achieve a 50% reading on the power
monitor bar graph. If the liquid is discharged into an open container or a low-
pressure line, the pressure can be increased by reducing the flow rate with a valve
on the discharge side. Unless absolutely necessary do not operate the power
supply continuously with the amplitude set above 90%.
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%) when
the flow cell is empty or when using a probe without the flow cell and the probe
is in air (out of the sample), check the instrument without the probe to determine
if the probe has failed or is out of tune. 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
If the START key is pressed and the time limit has not been set, processing will
remain uninterrupted until the STOP key is depressed.
If the START key is pressed and the time limit has been set, processing will
remain uninterrupted until the set time limit expires, or the STOP key is pressed
– whichever occurs first.
If a footswitch is use, and the time limit has not been set, processing will remain
uninterrupted as long as the footswitch is depressed.
If a footswitch is used, and the time limit has been set, processing will remain
uninterrupted until the time limit expires or the footswitch is released –
whichever occurs first.
The START key and footswitch are mutually exclusive. If the process is initiated
by the START key, the footswitch becomes inoperative. If the process is initiated
by the footswitch, the STOP key becomes inoperative.
