Sonics VC70T - Manual (Page 11)

CAUTION
• Do not operate the power supply unless it is connected to the converter.
• Never allow a microtip to vibrate in air for more than 10 seconds.
• Do not allow the vibrating probe to come in contact with anything but the sample.
1. Immerse the probe into the sample .
2. For continuous operation with units equipped with a pulsing button, set the PULSE /
CONTINUOUS switch to CONTINUOUS. For pulsed operation, set the PULSE /
CONTINUOUS switch to PULSE. Then set the AMPLITUDE control to 40.
3. For continuous operation with units not equipped with a pulsing button, set the
AMPLITUDE control to 40.
4. For pulsed operation set the PULSER as required.
5. For timed operation set the TIMER as required and depress the TIMER knob.
6. If necessary, rotate the AMPLITUDE control to increase or decrease the intensity as
required.
IMPORTANT
Proper care of the probe is essential for dependable operation. The intense cavitation will,
after a prolonged period of time, cause the tip to erode, and the power output to decrease
without showing up on the wattmeter. The smoother and shinier the tip, the more power will
be transmitted into the sample. Any erosion of the probe tip will increase the rate of future
erosion. For that reason it is recommended that after every 5 or 6 hours of use the tip be
examined, and if necessary, polished with emery cloth or an abrasive wheel. Since the probe
is tuned to vibrate at a specific frequency, it is most important that only the contaminated
surface be removed. This procedure can be repeated as long as the wattmeter reads less than
20 watts with the probe out of the sample, when the AMPLITUDE control is set at 100. If
the wattmeter reads over 20 watts the probe or replaceable tip should be changed.
