SECTION III – SERVICE INFORMATION
Your Ultrasonic Processor was designed to provide you with years of safe and
dependable service. Nevertheless, because of component failure or improper usage, the
possibility does exist that it might not perform as it should, or that it will stop working all
together. The most probable causes for malfunction are listed below and should be
investigated.
T he unit was plugged into an electrical outlet that provides a different voltage from
that required. See Electrical Requirements.
T he probe is not secured properly.
I f the probe has a replaceable tip, the tip is not secured properly, or the probe has been
used with low surface tension liquids.
A fuse(s) has failed. If a fuse(s) has failed, proceed as follows:
1. Ensure that the power switch is set to OFF.
2. Open the fuse holder cover(s).
3. Replace the fuse(s).
4. Set the AMPLITUDE control to 50 and the power switch to ON. With the probe
in air (out of sample), the wattmeter should read below 20 watts. If the reading
exceeds 20 watts, set the power switch to OFF, and disconnect the probe from the
converter.
5. Set the power switch back to ON. If the wattmeter reads below 20 watts, the
probe has failed or is out of tune due to excessive erosion, and should be replaced.
If the wattmeter reads above 20 watts, either the converter or power supply has
failed and the complete Ultrasonic Processor should be returned for repair.
