Section 1

Warnings and Cautions
Ignoring the following cautions could cause injuries or property
damages.
Indicates a hazardous situation which, if not avoided, may result in
minor or moderate injury.
Do not touch the top plate or any object near it even when the heater is
turned off. You may get burned due to residual heat.
After using this equipment, make sure to turn off the main power switch
and also to disconnect the power cord from the power outlet for the
safety of other users.
Do not place heavy objects, including this equipment, on top of the
power cord and do not strip, scratch, bend, twist, pull, or heat the power
cord. Adamaged power cord is a fire and electrical shock hazard.
Make sure to set up this equipment on a flat, stable, clean, non-slip,
dry, and fireproof surface inside a lab with proper safety measures.
Do not place any device which can be affected by the motor vibrations
near this equipment.
Do not touch the power outlet, power socket, or power cord with wet
hands. And make sure to connect the power cord directly and firmly to
the power outlet and power socket.
Do not put or insert any objects (especially if conductive or flammable)
inside this equipment.
Do not expose this equipment to any heat sources including direct
sunlight.
Beware that mechanical shock or vibration can damage this equipment
and pay extra attention while moving it. Damages caused by
mechanical shock or vibration may result in injury or fire.
Do not impact the top plate or heat sink. You can damage the
equipment or get injured.
Do not install this equipment near any device that generates high
frequency noise such as high frequency welding machines, high
frequency sewing machines, or SCR power controllers.
Before cleaning, make sure to unplug the power cord to avoid electric
shock or fire.
Do not use chlorine bleach, ammonia-based cleaners, abrasives,
ammonia, or metal scouring pads. Wipe with a soft damped cloth or a
sponge soaked in water or diluted neutral detergent.

Section 2 Functional Description
The Fisher Scientific Isotemp RT AVCD HPS model offers temperature
and control by external temperature probe. This unit also boasts quick
heat-up time thanks to ample heating capacity as well as the superb
heat transfer rate enabled by the tightly integrated structure of the
heater and the ceramic-coated aluminum alloy top plate. Also provides
a variety of temperature modes relating to temperature control, heat-up
time.
Features
•By adopting a special magnet with exceptionally strong magnetic
coupling power as well as smooth-start stirring mechanism. You will
experience virtually no decoupling of magnetic stir bars even with
viscous media or at high speeds (30~2000rpm, guaranteed). The
BLDC motor and the special magnet also provide big stirring power.
•Real-time stirring with quick operation or stop
•When the external temperature probe is coupled, it automatically
changes to external sensor mode. User can check media
temperature also control.
•Microprocessor PID Feedback Control
Fast and precise temperature control is provided by the
microprocessor PID controller.
•Selection of the Temperature Control Modes
Three user-selectable temperature control modes are provided for
your convenience; Optimum, Fast, and Slow.
•Auto-Tuning
Automatic tuning of the PID parameters provides more accurate
temperature control.
•Changing Temperature Limit
The top plate temperature control range can be changed to protect
media by changing over temperature limit value or low temperature
limit value.

Section 2
Functional Description
Features
•Offset
To use your own thermometer for temperature control in specific
applications, there can be some differences between the temperature
of your thermometer and the displayed temperature of this unit. If
needed, you can offset such temperature differences ranging from -
10°C to ±50°C at 0.1°C intervals.
•Selection of the Timer Mode
Immediate Activation (T1): The timer starts immediately after setting
the timer, Delayed Activation (T2): The timer is activated only when
the set temperature is reached.
•Quick Heat Up Time
Ample heating capacity and superb heat transfer rate of the tightly
integrated structure of heater and ceramic-coated aluminum alloy top
plate allow quick heat up time.
•The ceramic-coated top plate is highly resistant to heat and corrosion.
In addition, its white color is optimal for monitoring color changes of
the media during operation.
Safety
•Hot Top Warning Indicator
The top plate temperature can remain very hot for some time even
after the heater is turned off. To prevent injury or fire under such
circumstances, this instrument has a hot top warning indicator on the
control panel. This indicator will illuminate if the top plate temperature
is over 50°C. Even so, do not rely on this indicator alone for your
safety
•Overheating prevention device
Basically built in electronic overheating prevent device and
mechanical body overheating prevent device.
•Heating plate overheating prevention device
A heating plate overheating prevention device is particularly built-in.
•The devices overheat warning function
The devices WARNING LED will be lighted. In case of the devices
temperature goes over safe range.
