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, shut down due to an overload
condition or that it will stop working all together. The most probable causes for
malfunction are listed below and should be investigated.
The unit was plugged into an electrical outlet that provides a different voltage from
that required. See Electrical Requirements.
The probe and/or microtip is not secured properly.
If the probe has a replaceable tip, the tip is not secured properly, or the probe has
been used with samples containing solvents or low surface tension liquids.
A fuse(s) has failed. If a fuse(s) has failed, proceed as follows:

Replace the fuse(s).
4.
Reconnect the line cord to the electrical outlet, press the key and set the

5.
Press the key. If the wattmeter reads below 10 watts, the probe has failed or
is out of tune due to excessive erosion, and should be replaced, if the wattmeter
reads above 10 watts, either the converter or power supply has failed and the
complete Ultrasonic Processor should be returned for repair.
