Heating Operation Principles
The heating element and a temperature sensor are located just eneath
the ceramic top surface of the product. The microprocessor controlled
heat, generated y the heating element, is ased upon the sensor tem-
perature and the value set on the Heating Temperature Display. When
the sensor temperature is not within range of the value set on the dis-
play, the display will FFLLAASSHH. When the sensor temperature is within
range, the value displayed will remain constantly OONN.
The Heating Temperature Display does not indicate the actual tempera-
ture of materials placed on top of the product or the actual temperature
of the ceramic top surface.

The ta le elow shows a typical difference etween the temperature set
on the Heating Temperature Display and the actual temperature meas-
urement of the ceramic top surface:

Temperature Set Top Surface Temperature Set Top Surface

(The information a ove was taken using a 6795-420D with no top load
in 20°C am ient conditions)
Using the Externa Temperature Contro er, Corning Inc. Cat. No.6795PR
enab es precision temperature contro of materia s p aced in vesse s on top of
the product.
An External Temperature Controller is availa le for this product as an
accessory item. See page 11 for more details.
When the External Temperature Controller is connected to the product,
the closed loop control process descri ed previously is extended to
include temperature input from the External Temperature Controller.
The microprocessor controlled heat, generated y the heating element,
is ased upon the sensor temperature located in the tip of the External
Temperature Controller and the value set on the Heating Temperature
Display. When the sensor temperature is not within range of the value
set on the display, the display will FLASH. When the sensor temperature
is within range, the value displayed will remain constantly ON.
When the External Temperature Controller is connected to the product
and properly placed into a liquid on the top surface, then the Heating
Temperature Display does indicate and directly control the actual tem-
perature of the liquid on the top surface.
Caution: The top surface and the vessel used may e at su stantially
higher temperatures than indicated y the setting on the Heating Temp -
erature Display as the controller regulates the liquid temperature inside
the vessel.
Heating Operation Safety
The microprocessor controlled system has error routines uilt in to
detect product operation in some unfavora le conditions. The type of
error routines which may e active in a product varies depending upon
the functionality of the model and the operating software version.
If an error routine is engaged, the product will typically shut down.
Some error routines will display an error code num er in the left digital
location of the Heating Temperature Display when the product is shut
down. For more information on error codes, call Corning Technical
Service at 978.442.2200.
A product shut down y an error routine must e disconnected and
reconnected to mains input efore it can e used again. Please contact
Corning Inc. or a Corning Authorized Repair Facility if a product does
not reset from the error routine shut down or if it continues to shut
down after resetting.
Caution: Error routines uilt into these products do not su stitute the
need to use these products per the specified operating conditions and
according to safe la oratory practices. There are potential failure modes
in product functionality or in process of use that could result in uncon-
trolled or unexpected heating of the top surface. Reaction plans should
e developed and safety precautions put in place ased on the worse case
scenario that any materials placed on the top surface could e su jected
to a continuous supply of heat, raising the material temperature to levels
in excess of 550°C.
Product Repair
There are no direct user servicea le components inside this series of
products. A list of availa le replacement parts are listed on page 12.
Please contact Corning or a Corning authorized repair facility for
repair or maintenance issues.

Frequently Asked uestions
◗I have a beaker of water on my hot plate and set the temperature
for 550°C. Why does the display setting blink and not remain
constant?
The display will link at any time when the temperature sensor is not
within range of the set temperature value. The temperature measured
y the sensor is a composite of the temperature of the heating element
located eneath the sensor, the ceramic top a ove the sensor, and the
very small air space around the sensor. Water requires a su stantial
amount of heat in order to oil yet remains at a constant temperature
of 100°C for the duration of the oiling process. Although the heating
element is producing maximum heat at the 550°C setting, the water
consumes this heat so quickly during the oiling process that the heat
is una le to raise the temperature measured y the sensor to within
range of the 550°C set value.
◗How long does it take to bring a beaker of water to boil?
Using a 600 mL PYREX®eaker with 400 mL of water at 25°C, it
takes approximately 15 minutes to ring the water to a full, rolling
oil.
◗Can I use a metal tray on top of my Corning®hot plate?
No. The metal will act as a heat sink, and have a high pro a ility of
creating an a normal heating condition. If an a normal condition is
detected, the product will shut down. A metal vessel will also scratch
the ceramic top plate.
◗The stir bar keeps decoupling. Why and what can I do to stop this?
These units are programmed to minimize decoupling. However, liquid
viscosity, stir ar magnetic strength, vessel used, and speed changes can
cause decoupling. High viscosity liquids must e stirred at slower speed
settings. The magnetic strength of stir ars can weaken over time and
may need to e replaced. Vessels used need to have thin, flat ottoms
to insure optimal performance. Rapid decreases in stir speed can cause
decoupling as the magnet slows down quicker than the stir ar and the
liquid.
◗What size vessel should I use?
Vessels used on the top of a hot plate must not e larger than the
top plate.
