4. DESCRIPTION OF MAJOR COMPONENTS
Generator
Includes all operatingcontrols and indicators, detachable three-wiregroundedlinecord,fuse,external
power control jack and high frequency cable connector.
Process Control Feature of the Sonicator3000
• Microprocessor Controller -allows precisecontrolof output amplitude,elapsedprocessingtime,
and cyclical rates during power pulsing. It encompasses the functions of the Digital IntegratingTimer
and the Multi-Range PULSAR & Cycle Timer.
• Digital Integrating Timer - permits precise timing of ultrasonic energy, which can be applied in
one-second increments from one-second to 100 hours. The total desired processing time is entered
on the keypad. Both the processing time selected and actual total elapsed processing time is
indicated by an LCD readout. A start/stop control initiates or reinitiates timed ultrasonic processing.
A pause control allows manual pulsing or delay. The total preset time of active ultrasonic processing
is unaffected by pauses or pulsing,whether by hand or with the Multi-Range PULSAR & CycleTimer.
• Multi-Range PULSAR &Cycle Timer - permits the application of ultrasonicenergytothe sample
on a pulsed basis. Pulse on and off times are adjustable in 0.1-second increments from 0.5 seconds
to 1 hour each. Pulsed operation permits high intensity sonication while avoiding heat build-up in the
sample. It also allows particulate material being processed to settle back under the tip.
• OVERLOAD INDICATION - under certain load conditions, the amount of power supplied to the
convertor/horn assembly might overload the circuitry of the generator to the point of failure. In order
to prevent damage to the generator, an overload protection feature has been built intotheunit. When
the output power exceeds design specifications, the output power will be disabled. The following
prompt will appear: "OVERLOAD! Press CLEAR to RESET". The PowerKnob display will flash “888”,
and the alarm will beep.
• Temperature Monitoring/Control of Processed Liquids
The temperature probe can be placed in the liquid being processed to monitor the temperature, to
shut down the unit when a programmable maximum temperature is reached, and to activate an
external cooling device to cool the liquid being processed. Note:Do not allowthe temperature probe
to come in contact with the Horn or Probe.
Convertor (Transducer)
The convertor is a gray, cylindrical unit (mounting area), and black colored front driver (the first stage
of acoustic amplification) with a ½”- 20 threaded hole for horn attachment. A detachable high-
frequency cable is also supplied.
Horn (Probe)
A horn is a 5”resonant body that steps down from 1 ½”to a specific diameter tip. The horn serves as
the second stage of acoustic amplification. The horn may be solid or have a removable tip and is
supplied with a ½”–20 threaded stud for attachment to the convertor and externalthreadsaround the
body for attachment of accessories such as a Microtip. Horns are available in three standard tip
diameters of ½”, ¾”or 1" and come in three different tip configurations. Tapped horns have a
replaceable Flat Tip; Solid horns do not have a replaceable tip; and Sapphire tipped horns have a

1/16" thick sapphire disk bonded to the tip of a solid horn.
Replaceable Flat Tips
Tapped horns have replaceable flat tips, at the radiating surface attached to the end of the horn.
The flat tips will erode with use and are replaceable. Tip size matches horn diameter.

6. PREPARATION FOR USE
1. To safeguard the fuse against failure, always switch the powersupplyoff before connecting or
disconnecting the power cord.
2. Check to make sure that the Power Switch on the generator is turned OFF.
3. Connect the Power Cord to the receptacle on the rear of the generator and plug it into a
grounded power outlet.
4. If the Sonicatorhas been left in a very cold environment for a prolonged period of time, do not
operate the unit until it has reached room temperature. Turn the power switch ON, without
processing any samples, for 20 minutes before using, to warm-up the electronics faster.
5. The horn and its flat tip were assembled and attached to the convertor at the factory, but it is
recommended that you check the tightness of the horn and flat tip by using the wrenches
provided and referring to 6-3 &6-4 of this manual. An insufficiently tightened horn or tip might
cause damage to the generator circuitry or parts of the convertor and horn. NEVER assemble
or disassemble the probe by holding the convertor in a vise or while power is on. ALWAYS use
the wrenches supplied with the unit.
6. When replacing horns or horn tips, clean the mating surfaces of the convertor and probe or
stepped microtip as well as the threaded stud and hole. Check that the stud is tight. Do NOT
apply grease to mating surfaces or threads of the convertor, horn, replaceable flat tip or
microtip probe.
7. Mount the convertor and horn into the sleeve on the top of the SONABOX™Acoustic
Enclosure (Part # 432B) or use the Convertor Stand and Positioner (Part # 438) to hold the
convertor and horn in position. Support the convertor only by clamping around the outer case
(See 6-2).
Do NOT hold or clamp the convertor, on the black portion or the titanium horn itself.
9. Connect either end of the coaxial HIGH FREQUENCY cable to the rear of the chassis and the
other end to the receptacle on the convertor. Push the connectors in and turn the chrome rings
clockwise ¼ turn to secure the connectors.
10. If a foot switch or timer switch is used, plug it into the FOOT SWITCH CONNECTOR. Make
sure that the plug is inserted properly.
11. If you will be using a MICROTIP or Extender, remove the Flat Tip on the end of the horn, then
attach the MICROTIP or Extender in its place. (See 6-3, 6-4)

ATTACHMENT AND REMOVAL OF HORNS AND TIPS
To connect a horn to the convertor or a tip to a horn:
1. Thread pieces together by hand until all joints mate smoothly and are hand tight.
If resistance is met, avoid cross threading by loosening and rethreading by hand.
2. Do NOT force the threads by wrenching.
3. Tighten using wrenches as explained below, being sure to apply even and firm pressure.
To attach or remove a horn:
1. Insert the pin of the pin spanner wrench supplied with the Sonicator(as shown in the
diagram on page 6-4) into one of the holes at the base of the horn.
2. Insert the pin of the second pin spanner wrench into one of the holes in the front driver
(black portion) of the convertor.
3. Apply even and firm pressure in the appropriate direction.
To attach or remove a Flat Tip, Microtip or Extender:
1. Insert the pin of a pin spanner wrench into one of the holes at the base of the horn.
2. Place the 7/16" open-end wrench on the wrench flats of the Flat Tip, MICROTIP or
Extender.
3. Apply even and firm pressure in the appropriate direction (see next page for diagram).
CAUTION!
An insufficiently tightened horn, probe or tip will impede the transmission of ultrasonic energy and may
cause damage to the generator circuitry or mating parts of the convertor and horn.
Warning: An improperly tightened horn or horn tip may heat up and fail prematurely. NEVER
assemble or disassemble the probe by holding the convertor in a vise. Always use the tools provided
with the unit and place a firm mat or towel underneath the convertor and horn to prevent slippage or
damage. Avoid pressing the sides of a MICROTIP or Extender down into a counter top whentightening
or removing, as this may damage the tip.
A loud, high piercing sound emanating from the horn or probe indicates that one of the components
may be loose or possibly cracked. STOP processing immediately. Turn off the generator and check
the tightness of the horn to the convertor, and the tip or probe to the horn if applicable. If the loud
noise persists, contact MISONIX for assistance.

1) Selecting a Programmed Memory Setup
There are nine possible program memories that store programmed setup information, and maintain those
programmed parameters even after turning off the unit. Any one of those nine memory setups (Program
numbers) can be accessed by pressing the associated numeric key, [1] to [9], on the keypad(i.e.:pressing
the [5] key will bring up the programmed settings for Program 5). For all program memories, all timing
parameters and output levels are factory programmed to zero, with no temperature control.
2) Running the Current Program
The Program that is currently displayed on the five alternating screens can be run by pressing the START
key.
3) Accessing the MENU Options
By pressing the MENU key, options are shown to change the temperature units (degrees Celsius or
Fahrenheit), and to select whether the knob value should be stored when processing is stopped.
4) Returning to the MicroTip Question
If it is necessary to change the answer to the MicroTip question, press CLEAR when the five screens are
being displayed.
5) Programming a Memory Setup
Pressing the PROG key when the five screens are alternating will access the ProgrammingMode, inwhich
any or all programmed values can be changed for the currently displayed Program.
NOTE: Any of the following screens that prompt for a settable parameter will always show the currently-
programmed value, such that pressing ENTER/YES will skip to the next screen. After any value is changed
AND ENTER is pressed to store that value, when the next screen appears, the EXIT key can be pressed to
revert to the initial five screens. All parameters afterthe value that was changed will be retainedin memory.
For example, a Program has the following parameters: Process Time = 00:10:00, Pulse-ON Time = 00:02.5,
Pulse-OFF Time = 00:10.0, Initial Level = 4.0, and only using Temperature Monitoring (no temperature
control). If it is desired to onlychange the Pulse-OFF time to 00:05.0, press PROG when the five screensare
cycling, then press ENTER twice to bypass the Process Time and Pulse-ON time. Key-in [5][0] and press
ENTER, then press EXIT. The Initial Power Level and temperature settings will remain as previously set.
Process Time Programming
The first display that appears will show the following screen, with the bottom line alternating at three-
second intervals:
00:00:00 (hr:min:sec)
Set Total Process Time 00:00:00 (hr:min:sec) Then Press ENTER
The actual value shown will depend on whether a value was previously programmed.
The “Process Time”is the total processing time desired. When running this Program, processing will
continue until the Elapsed Time equals this programmed Process Time. Note that Elapsed Time is only
counted when the horn is “ON”, therefore, only “ON-Time”is counted. Pressing CLEAR at any time will
zero the Process Time value. Setting this value to 00:00:00 will allow the unit to run “forever”with no
automatic shutdown (see “Elapsed Time Counter”). The maximum value allowed is 99:59:59. When
finished keying in the desired value, press ENTER.

Operation Manual S3000 OPERATING INSTRUCTIONS
7-5
Pulse-ON Time Programming
After entering the desired Process Time, the next screen prompts for the Pulse-ON time, with the top line
alternating at three-second intervals:
Set Pulse “ON” Time
00:00.0 (min:sec.tenths) Then Press ENTER 00:00.0 (min:sec.tenths)
If processing continuously, (no pulsing), enter 00:00.0 for the Pulse-ON time andpress ENTER. This will
also skip asking for a Pulse-OFF time.
The minimum Pulse-ON time is 0.5 seconds. Key-in any value from 00:00.5 to 59:59.9, or 00:00.0, then
press ENTER.
Pulse-OFF Time Programming
After entering the desired Pulse-ON Time, the next screen prompts for the Pulse-OFF time (if 00:00.0 has
not been entered for the ON time), with the top line alternating at three-second intervals:
Set Pulse “OFF” Time
(min:sec.tenths) 00:00.0 Then Press ENTER (min:sec.tenths) 00:00.0
Key-in any value from 00:00.5 to 59:59.9, or 00:00.0, then press ENTER.
NOTE: Entering 00:00.0 for the Pulse-OFF time will assume that continuous mode is desired (no
OFF time) and the ON-Time will automatically be zeroed, which also indicates Continuous
Operation.
Setting Initial Output Level (Knob Setting)
After programming the ON/OFF times, the following screen will prompt the operator to obtain an initial
Power Knob setting:
Set Initial Output Level
(0.0-10.0): 0.0
Key-in a value from 0.0 to 10.0 (in 0.5 increments only), then press ENTER. This will be the knob setting
when START is pressed to begin processing. If set at 0.0, when START is later pressed to begin
processing, no processing will occur until the knob is turned clockwise to a value greater than 0.0.
Programming Temperature Monitoring
The next question asked after setting the initial knob setting is as follows:
Temperature Monitoring
(Y/N)?
If a shutdown temperature or controlled-device temperature will be used, or if the temperature will be
displayed with no temperature control, answer YES to this question. If the temperature probe will not be
used, answer NO to this question. Pressing NO will revert the display to the initial five-screens for the
Programming Mode (i.e.: no further programming information is required).

Operation Manual S3000 OPERATING INSTRUCTIONS
7-6
Programming Temperature Control
If YES is pressed for the Temperature Monitoring question, the next question asked is:
Temperature Control
(Y/N)?
Answer YES if a maximum shutdown temperature or external control temperaturewillbeused. Answer NO
if the temperature will be shown on the display while processing, but with no temperature control.
Answering NO will revert the display to the initial five-screens for the Programming Mode. A maximum
shutdown temperature MUST be entered if external device control will be used.
If YES is pressed, the operator will be prompted to enter the temperature at which processing will stop:
Set MAX Temperature
For Shutdown: 0oC
Using the numeric keys, enterthe desired maximum temperature for shutdown. Theallowabletemperature
range is –50oC to +121oC (-46oF to +250oF). The sign, “+”or “-”, can be toggled bypressing the “+/-”key.
After keying in the numbers, press ENTER.
Programming the Control of an External Device
After entering the maximum shutdown temperature, one final question will be asked:
Controlling an
External Device (Y/N)?
This question is asking whether ANY external device will be controlled by the temperature probe. Usually
this will be a cooling device to keep the temperature of the sample below a given temperature, but any
device, such as an alarm, may be controlled.
If NO is pressed, the screen will revert the display to the initial five-screens for the Programming Mode.
If an external device will be controlled, press YES and the operator will be prompted as follows:
Set Temperature to
Activate Device: 0oC
Using the numeric keys, enterthe desired temperature when the external device should be activated. The
allowable temperature range is –50oC to +121oC (-46oF to +250oF), but the temperature MUST be less
than the previously-set maximum shutdown temperature. The sign, “+”or “-”, can be toggled by pressing
the “+/-”key. After keying in the numbers, press ENTER. The screen will revert the display to the initial
five-screens for the Programming Mode.
