7. Operating Instructions (Getting Started)
CAUTION
•
Do not operate the power supply unless it is connected to the converter.
•
Never allow liquid to spill into the converter.
•
Do not allow a Microtip to vibrate in air.
•
Do not allow the vibrating Microtip to contact anything but the sample.
•
Never place a washer between the converter, probe or horn.
•
Never apply grease to the mating surfaces or threads of the converter, probe or Microtip.
•
Should it become necessary to remove a probe, use the wrenches supplied.
Never
attempt to remove the probe by twisting the converter housing or holding it in a vice, as
this may damage the electrical connections within the housing.
CAUTION
LOW SURFACE TENSION LIQUIDS – ORGANIC SOLVENTS
The probes (solid or with a replaceable tip) are tuned elements that resonate at a specific frequency. If
the replaceable tip is removed or isolated from the rest of the probe, the element will no longer resonate
at that frequency, and the power supply will fail. Unlike aqueous (water based) solutions which rarely
cause problems, solvents and low surface tension liquids are problematic. These liquids penetrate the
probe/replaceable tip interface, and force the particulates into the threaded section isolating the tip from
the probe.
When processing low surface tension liquids, ALWAYS use a solid probe.
Set-up:
1. Connect the power cord into the receptacle on the rear of the ultrasonic processor.
2. Make sure the unit is switched off. Plug the electrical line cord into the electrical outlet.
3. If the optional foot switch is used, insert the plug into the jack located on the rear panel.
4. For best results it is critical to use the appropriate size and type of accessory to process
your sample. If you are not sure that you have the proper horn for your sample volume
please refer to the Accessories section of this manual or call the manufacturer for
assistance.
5.
Horns/Probes must be properly tightened.
Depending on the accessories purchased,
often the horn and the flat tip are attached to the converter at the factory.
Check the
tightness of the horn and flat tip by using the wrench set
. Please refer to images in the
Maintenance section of this manual. A loose horn or tip may cause damage to the
generator circuitry or parts of the converter and horn. A loose horn may also show a
fluctuation in wattage readings.
Always use the wrenches supplied with the unit.
6. If you will be using a Microtip or extender, remove the flat tip on the end of the replaceable
tip probe, then attached the Microtip or extender in its place.
7. Horns and probe tips wear after normal usage. Using a severely worn probe tip can
damage internal generator components.
8. If using a laboratory stand, mount the convertor /probe assembly using a clamp. Be sure to
