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.

Section 2
Functional Description
Safety
•Error indication regarding external temperature sensor
In case of Error message, the Probe does not contain enough in
media or on air.
•A transparent shield is also provided to allow you to monitor your
operations more safely by shielding you against decoupled stir bars
or liquid splashes. (optional)
•Heating Bath (optional)
A specially designed non-slip heating bath comes with the
instrument. To prevent unintentional slips of the bath during
operation, this bath has concavo-convex bottom shown below so that
it can sit stably on top of the top plate.
Figure 2-1. Heating Bath
Convenience
•Conveniently set indicating temperature and stirring speed by two
different knobs:
•In case of external temperature probe coupled, automatically change
to external sensor mode.
•The external temperature probe (sensor) is made by Pt material. So,
the probe (sensor) can be fix easily on lab ware.
•Showed on digital display- top plate temperature, Probe measuring
temperature, stirring speed, timer setting value, and remaining time
value.
•In case of the stirring media viscosity change, the feedback function
maintains regular speed.

Section 2
Functional Description
Convenience
• Smooth-start stirring system reduces magnetic bar decoupling.
• Two support rods are provided to hold various kinds of devices such
as temperature sensors, thermometers, laboratory glassware, etc.
(optional).
• User designation temperature range
Your own temperature limit can be easily set and protect simple from
controlling time or user mistake.
• User designation stirring speed range
User can set up the lowest stirring speed. So the device can be
stirring as quickly as possible time.
