"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.
Note
The knob does not function unless
one of the "SET" buttons is pushed
first to activate it.
Power Button
The SUPER-NUOVA unit has a power button located on
the front control panel. The unit may be powered on by
pressing the power button or ANY button on the control
panel. When the unit is turned on, there will be three
beeps, the unit will initialize and then "OFF" will be dis-
played on both the "HEAT" and "STIR" display screens
until a temperature and/or stirring speed are entered. To
turn off power to the unit, press the power button.
Setting the Stirring Speed
The SUPER-NUOVA stirring hot plate has an electronic
feedback speed control which will maintain a precise
speed setpoint from 50 rpm through 1200 rpm. (Maximum
speed is dependent on viscosity of the solution.) The
SUPER-NUOVA stirring hot 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 "SET" key located under
the STIR display. Use the knob in the center of the con-
sole 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" key under the STIR display or wait a moment
and the unit will beep indicating that it has been set. The
SET indicator light will be lit when in SET mode.
Once the unit begins stirring, the display will register
ACTUAL speed until the setpoint has been reached. To
check the setpoint, press "SET" under the STIR display
and your setpoint will be displayed again for a few sec-
onds. The display will automatically return to indicating
actual speed. To stop the stirring action without changing
your setpoint press the PAUSE button once. The PAUSE
indicator will be lit and the word PAUSE will scroll across
the display. To resume stirring at the set speed, press the
PAUSE button again.
To turn stirring off, press "SET" under the STIR display
and turn the knob counterclockwise until the display reads
"OFF." Alternatively, the stirring can be turned off by
pressing and holding the "SET" STIR key until a beep is
heard (approximately 3 seconds.)
