The table below shows a typical difference between the temperature set
on the Heating Temperature Display and the actual temperature meas-
urement of the ceramic top surface:

(The information above was taken using a 6795-420D with no top load
in 20°C ambient conditions)
Using the External Temperature Controller, Corning Inc. Cat. No.6795PR
enables precision temperature control of materials placed in vessels on top of
the product.
An External Temperature Controller is available 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 described previously is extended to
include temperature input from the External Temperature Controller.
The microprocessor controlled heat, generated by the heating element,
is based 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 be at substantially
higher temperatures than indicated by 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 built in to
detect product operation in some unfavorable conditions. The type of
error routines which may be 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 number 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 by an error routine must be disconnected and
reconnected to mains input before it can be 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 built into these products do not substitute the
need to use these products per the specified operating conditions and
according to safe laboratory 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
be developed and safety precautions put in place based on the worse case
scenario that any materials placed on the top surface could be subjected
to a continuous supply of heat, raising the material temperature to levels
in excess of 550°C.
Product Repair
There are no direct user serviceable components inside this series of
products. A list of available replacement parts are listed on page 12.
Please contact Corning or a Corning authorized repair facility for
repair or maintenance issues.
Product Maintenance
Power
Caution: Disconnect power to the product by unplugging the power
cord before performing any maintenance or inspection procedures.
Inspect the power cord regularly and replace if damaged. Use only
Q
replacement power cords available from Corning and Corning
authorized product distributors.
