Please read all the information in this manual before
operating the unit.
Your SUPER-NUOVA Multi-Place plate is a heating and/or
stirring plate designed for laboratory procedures requiring
precise control of temperature and/or stirring speed. Each
SUPER-NUOVA Multi-Place includes a digital display for
monitoring temperature and/or stirring speed, and the stir-
ring hot plate models have dual displays so temperature
and stirring speed can be monitored simultaneously. The
hot plate is capable of producing accurately controlled top
plate temperatures from 1°C through 370°C. The temper-
ature is controlled at the plate surface by an internal Type
K thermocouple sensor, or the solution temperature may
be controlled by utilizing the included 6" PFA encapsulat-
ed ungrounded stainless steel Type K thermocouple
probe. A 6" or 10" general purpose stainless steel immer-
sion probe, or a chemical-resistant 7" solid Teflon®immer-
sion probe may be ordered separately. The stirrer will
accurately maintain stirring speeds from 50 rpm up to
1200 rpm. On stirring hot plate models, the accessory
probe may also be utilized to display the actual tempera-
ture of heat-sensitive solutions during stirring-only func-
tions. The top plate on the SUPER-NUOVA Multi-Place
plates are solid ceramic, and are suitable for use with
glass or metal vessels and sand baths.
Other features of the SUPER-NUOVA Multi-Place include
a timer that can be used to shut off stirring, heating or
both. Specific temperature or stirring speed setpoints
may be set using the PRESETS buttons on the SUPER-
NUOVA Multi-Place. An over temperature protection
(OTP) circuit can be set using the adjustment on the front
face of the unit. The OTP can be displayed in the service
menus. See “Service and Calibration.”
An RS232 port is available on the SUPER-NUOVA Multi-
Place to output elapsed time, stirring setpoint (for each of
the stirring positions), actual stirring speed (for each of
the stirring positions), heating setpoint, and actual tem-
perature. (Actual temperature refers to top plate tempera-
ture, or remote probe temperature if a probe is being
used.) The data is printed once every second when the
unit is powered on (displays on). See “RS232 Output” in
the Operation section of this manual.

Each SUPER-NUOVA Multi-Place utilizes the latest micro-
processor technology to deliver the most reliable, accu-
rately controlled, ceramic top plate on the market.
Your SUPER-NUOVA Multi-Place has an electronic,
closed-loop feedback control which will maintain tempera-
ture setpoints from 1°C through 370°C.
The SUPER-NUOVA Multi-Place plates use a Type K
thermocouple for measuring the top plate temperature,
OTP and the external probe. Both top plate surface and
OTP temperature are measured with independent analog
circuits. This provides a significant increase in safety due
to the redundancy of the circuits. It is possible to heat cer-
tain types of metal vessels and sandbaths on the
SUPER-NUOVA Multi-Place without damaging the ceram-
ic top.
The electronic stirring speed control will maintain the
speed setpoint when the unit is loaded. The motor is com-
bined with a powerful magnet to provide exceptional mag-
netic coupling with a stir bar.
The timer feature on the SUPER-NUOVA Multi-Place can
be programmed to turn off the stirring, heating or both.
The default setting is to turn off heating only. See
“Setting the Timer” section of this manual. To change
default setting, see “Service and Calibration/Timer
Shutdown”.
Use the space-saving, SUPER-NUOVA Multi-Place stirrer
or stirring hot plate to perform multiple operations at once.
12
Principles of Operation
Note
This plate does not cool. The mini-
mum temperature is 1°C if used in a
cold room at 1°C.

13
Power Button
The SUPER-NUOVA Multi-Place has a power button
located on the front control panel. The unit may be pow-
ered on by pressing the power button or ANY button on
the control panel. When the stirring hot plate unit is
turned on, there will be three beeps, the unit will initialize
and then “OFF” will be displayed on the “HEAT” and
“STIR” display screens until a temperature and/or stirring
speed are entered. When the stirrer unit is turned on,
there will be three beeps, the unit will initialize and then
“OFF” will be displayed on the “STIR” display screen until
a stirring speed is entered. To turn off power to the unit,
press the power button.
Using the Stirring Function
The SUPER-NUOVA Multi-Place has an electronic feed-
back speed control which will maintain a precise speed
setpoint from 50 rpm through 1200 rpm. Stirring speed
stability is 2.0% at speeds greater than 200 rpm.
(Maximum speed is dependent on viscosity of the solu-
tion.) The SUPER-NUOVA Multi-Place plates are
equipped with a strong magnet and high torque motor
which will draw a vortex in fluids up to 700 cp.
To set the stirring speed, press desired stirring position
key (1-4) located under the STIR display. Use the knob in
the center of the console to select a speed. Turn the
knob clockwise to increase the speed or counterclockwise
to decrease the speed. When desired speed has been
reached, press same key (1-4) under the STIR display or
wait a moment and the unit will beep indicating that it has
been set. Repeat for each individual stirring position.
After stirring speeds have been set, the indicator lights
will alternate to each position, displaying each stirring set-
point.
To set all positions to the same stirring speed, press the
“SET ALL” key under the STIR display. Use the knob in
the center of the console to select a speed. Turn the
knob clockwise to increase the speed or counterclockwise
to decrease the speed. When desired speed has been
reached, press the “SET ALL” key again or wait a
moment and the unit will beep indicating that it has been
set.
Operation
Note
The knob does not function unless
one of the “SET” buttons is pushed
first to activate it. Pushing the knob
alone has no function.
Note
When the unit is initially plugged into
a power source, or when it is
unplugged and re-plugged in, the
display will flash dashes and zeros
for a few seconds. This is simply an
initial check.

Once the unit begins stirring, the display will register
ACTUAL speed until the setpoint has been reached. To
check the setpoint, press the corresponding stirring posi-
tion key (1-4 or “SET ALL”) and your setpoint will be dis-
played again for a few seconds. The display will automati-
cally return to indicating actual speed. To stop the stirring
action without changing your setpoint press the position
1-4 or “SET ALL” button, and hold until you hear a beep.
“PAUSE” will scroll across the display. To resume stirring
at the set speed, quickly press the the corresponding but-
ton again. You can pause all positions at once, by using
the “SET ALL” button, or pause individual positions.
To turn stirring off, press desired stirring position key (1-4
or “SET ALL”) under the STIR display and turn the knob
counterclockwise until the display reads “OFF.” It is pos-
sible to turn off all positions, even if the stirring speeds
were individually set and not by using the “SET ALL” key.
To turn stirring off to all positions, press “SET ALL” and
turn the knob counterclockwise until “OFF” is displayed.
For best performance at low stirring speeds, leave all four
motors running. If stirring is not desired in one or more
locations, take stir bar(s) out of flasks at those locations
and allow all four motors to run, rather than stop or pause
unused motor(s).
14
OPERATION
Note
Each motor can be paused individu-
ally or all motors at the same time.
See recommendations for best per-
formance when using low stirring
speeds.

Note
The temperature display will indicate
the actual temperature of the top
plate (1°-370°C). This plate does not
cool. The minimum temperature is
1°C if used in a cold room at 1°C.
Note
The top plate temperature will be
higher than your solution tempera-
ture. Use external probe to read
actual solution temperature.
OPERATION
Using the Heating Function
The SUPER-NUOVA Multi-place stirring hot plate has an
electronic closed-loop feedback control which will main-
tain temperature setpoints from 1°C above ambient
through 370°C. An unloaded hot plate will heat to maxi-
mum temperature in just 8 minutes. A “CAUTION HOT
TOP” light on the front panel will illuminate whenever the
top surface temperature exceeds 50°C. The temperature
may be controlled either at the top plate by the internal
Type K thermocouple sensor, or in the solution using an
accessory ungrounded Type K thermocouple probe. If a
probe is used, the “External Probe” light will be illuminat-
ed on the front panel. A 6” chemically resistant stainless
steel remote probe is included with the unit, alternatively
a 6" or 10" stainless steel general purpose immersion
probe, or a chemical-resistant 7" Teflon immersion probe
are available by calling customer service. See the
Accessories section of this manual. The SUPER-NUOVA
Multi-Place will accept any ungrounded Type K thermo-
couple probe, however the accuracy of probes other than
those tested and specified may not reach the probe accu-
racy rating designated.
To set the temperature, press “SET” key located under
the HEAT display. The red set temperature indicator light
will blink, indicating it is ready to be set. Use the knob in
the center of the console to select a temperature. Turn
the knob clockwise to increase the temperature or coun-
terclockwise to decrease the temperature. When desired
temperature has been reached, press the “SET” key
under the HEAT display or wait a moment and the unit will
beep indicating that it has been set. All plate positions
will heat to the same settings. You can not specify differ-
ent heating setpoints for the different positions.
Once the unit begins heating, the display will register
ACTUAL temperature until the setpoint has been reached.
To check your setpoint, press “SET” under the HEAT dis-
play and your setpoint will be displayed again for a few
seconds. The display will automatically return to indicating
actual temperature. Keep in mind, drafts and other tem-
perature fluctuations will affect temperature accuracy.
Note
Boiling times are dependent on solu-
tion volume and the surface area of the
flask that is exposed to the hot plate.
For example, when heating the same
amount of solution in a 2L flask vs. a
1L flask, the solution will heat about
20% faster.
Warning
Use caution when heating volatile
materials; top surface and element
can reach the “Flash Point
Temperature” of many chemicals.
These plates are not explosion proof.
Fire or explosion may result. Unit con-
tains components which may ignite
such materials.
Use appropriate hand and eye protec-
tion when handling hazardous chemi-
cals.
“Caution: Hot Top. Avoid Contact.” The
top plate of the unit can remain hot for
some time after use. A “CAUTION -
HOT TOP” light will remain on until top
plate temperature cools to below
50°C.

16
Controlling Solution
Temperature Using External
Probe
To control the solution temperature plug the included
probe or an ungrounded Type K thermocouple probe into
the probe receptacle located on the right side of the unit.
Be careful to observe the correct polarity of the probe
connector when inserting probe. Place the probe into the
solution. The display will indicate the actual temperature
of the solution as measured by the probe, and the probe
indicator LED on the front panel will be illuminated. Keep
in mind, drafts and other temperature fluctuations will
affect temperature accuracy.
The external probe offers more exact temperature control
than regulating the top plate by the internal sensor. If you
need to maintain a precise setpoint it is recommend to
use a probe to control the solution temperature instead of
controlling by the top plate temperature.
When using a probe with the SUPER-NUOVA Multi-Place
stirring hot plate it is recommended that a clamp on a
support rod be used to hold the probe in the solution.
To ensure accurate probe readings, as much of the probe
sheath as possible should be immersed in the solution.
Make sure the probe is immersed in the liquid and is not
located in air or outside of the solution in the center of the
stirring vortex. If the probe is plugged into the stirring hot
plate, but is not in solution while the heat control is oper-
ating, the temperature display will continue to indicate an
ambient temperature, and a probe out of solution error
will occur. Because the set point cannot be reached the
element will continue to supply heat to the top plate, and
the top plate temperature of 370°C may be reached. If the
remote probe does not sense a temperature change in 9
minutes the unit will display a heating error and shut
down. If more or less than 9 minutes is required, see
“Service and Calibration/Probe Response.”
OPERATION
Note
Only one external probe can be
plugged into the SUPER-NUOVA
Multi-Place, therefore only one of
the four positions can be monitored
in this manner.

Using Preset Programs
The SUPER-NUOVA Multi-Place features the option of pre-
setting 3 setpoints into its memory (A, B or C.) To program
a preset, adjust the heat and/or stir features to your desired
setpoints. Press and hold one of the presets and the unit
will beep indicating those setpoints have been stored in
memory. The presets will be held in memory, even if the
unit is unplugged, until you choose to override it with anoth-
er preset.
To activate one of the presets, quickly press the correspon-
ding letter and the stir and/or heat features will automatical-
ly adjust themselves.
A No. 2 pencil may be used to gently mark up writable pre-
set surface.
Heating Metal Vessels and
Sand Baths
Metal vessels and sand baths cannot be heated on most
solid ceramic tops because of the tendency for the metal
and the sand to reflect heat back into the top, eventually
exceeding the maximum temperature rating for a ceramic
top, which can cause it to break. Because of its advanced
electronic control, the SUPER-NUOVA Multi-Place is capa-
ble of regulating the top plate temperature. Metal vessels
and sand baths may be heated safely without the danger of
the ceramic top breaking.
Setting the Timer
The timer function on the SUPER-NUOVA Multi-Place can
be set to shut off stirring, heating or both, in all four posi-
tions at once. The timer can be set for a desired number of
hours (1, 2, 4, 8 or 12) or for a non-specific period of time
(Infinity symbol). To set the timer, use the right and left
arrows until the light above the number corresponds to the
desired time. The default setting is turning off heating only.
To change this setting, see “Service and Calibration/Timer
Shutdown.”

OPERATION
If at any time you wish to reset the timer, press the right
or left arrow keys until the indicator light corresponds to
your desired time. The unit will beep indicating it has
been reset.
One minute before shutdown, the unit will beep three
times and flash the 1 hour light. The unit will beep three
more times to indicate it has timed out.
Power Interruption Protection
If an interruption in power supplied to the SUPER-NUOVA
Multi-Place occurs, the unit will resume normal operation
after power is restored, as long as the interruption is no
longer than 10 seconds. If the interruption is longer than
10 seconds, the unit’s power will be off once the facility
power is restored.
Resume Button
The resume button will recall the operation being per-
formed when power is shut off to the unit. It applies to
both a voluntary power-off by using the power button, or if
power is lost due to an outage. If the outage lasts longer
than 10 seconds, once restored press “POWER” then
“RESUME” to recall the previous operation. If the power
is lost for less than 10 seconds, the unit will automatically
resume it’s operation.
Using the Probe with the
Temperature Display for
Stirring-only Applications
On stirring hot plate models, the probe can also be uti-
lized to monitor the actual temperature of your solution
when you want to stir the solution without heating. The
unit must be changed to “Thermometer” mode in order to
perform this operation. See “Service and Calibration/
Thermometer Mode.” To use the probe without heating
the solution, turn the knob counterclockwise until the dis-
play indicates "OFF.” The element will not supply heat to
the top plate.
Note
The display on the stirring hot plate
will indicated temperatures from 0 to
370°C when displaying temperature
from a probe. If the actual tempera-
ture is below 0°, the display will still
read 0. If the temperature is higher
than 370°, the display will still read
370.

RS232 Output
An RS232 port is available on the SUPER-NUOVA Multi-
Place to output elapsed time, speed, and temperature data.
The data is printed once every second when the unit is pow-
ered on (displays on). A comma separates each piece of
data so that it may easily be imported into a spreadsheet as
CSV (Comma Separated Values). The actual data stream
sent every second consists of: Elapsed Time, Stirring Setpoint
(for each of the stirring positions), Actual Stirring Speed (for
each of the stirring positions), Heating Setpoint, Actual
Temperature. (Actual temperature refers to top plate tempera-
ture, or remote probe temperature if a probe is being used.)
Elapsed time is a 1 second counter that rolls over to zero
again every 12 hours (43,200 seconds). The speeds are
given in RPM, and the temperatures are given in degrees
Celsius. When the unit is first powered on (displays turn on)
a header will print indicating the columns.
In order to communicate with the SUPER-NUOVA Multi-Place,
the computer connected to it needs to be set with the follow-
ing parameters:
• BITS PER SECOND: 57,600
• DATA BITS: 8
• PARITY: NONE
• STOP BITS: 1
• FLOW CONTROL: NONE
Also, the first time a unit is plugged in, a paragraph of diag-
nostics information will be sent via RS232 and can be viewed
with a terminal program. An example of the data that is sent
is: CSP, COS
70, 0
CSP = Calibration Set Point
COS = Calibration Offset
The Calibration Set Point is the temperature that the unit was
calibrated at when calibration was performed. The Calibration
Offset is the offset determined at the calibration temperature.

Using HyperTerminal w/RS232
With HyperTerminal you can store the RS232 output data
of a SUPER-NUOVA Multi-Place on a PC. NOTE: Other
terminal programs that capture RS232 data can be used
as well.
In order to follow this procedure, you must have:
• Microsoft Windows 95‚ or greater with
HyperTerminal installed (it is available from the
Windows installation CD if not installed already).
• A PC that has an available 9 pin DB-9 RS232
connector.
• WHX18 (Accessory) – PC to hot plate communi-
cations cable – Connect it from the back of the
hot plate to the communications port desired.
To etup HyperTerminal:
1. From the START menu of Windows‚ select
ACCESSORIES, COMMUNICATIONS, HYPER-
TERMINAL
2. Type in a name (example: SuperNuova) that
you would like to refer to the connection by in
the NAME box. You may also select an icon if
you would like. Then select OK.
3. Select the RS232 port that you plan to use to
connect to the hot plate (typically Com 1 or Com
2). Then select OK.
4. Under port settings, select the following:
• BITS PER SECOND: 57,600
• DATA BITS: 8
• PARITY: NONE
• STOP BITS: 1
• FLOW CONTROL: NONE
Then Select OK.
