even fatal accidents.
Understand all alert labels prior to operating this equipment. Never
remove or damage the alert labels.
Never move this equipment while under operation.
Never install or use this equipment in explosive or flammable
atmospheres.
Never use or store flammable or hazardous substances near to this
equipment.
Never use the equipment to heat flammable or hazardous substances.
Always wear proper protective gear (such as goggles, gloves, masks or
an apron) when using this equipment.
Never allow water, organic solvents, dust, or corrosive gases to get
inside the equipment.
Never immerse this equipment in water or operate it under water. Never
reach for this equipment if it has fallen into water.
Check electrical requirements described in this operation manual or on
the ID plate of this equipment before use. Connect this equipment to a
dedicated power outlet nearby.
Connect this equipment only to properly grounded power outlets to
protect you and your instrument. Do not ground to gas pipes or water
pipes.
Never install this equipment closer than 30 cm (12 inches) to a wall of
combustible material. Observe minimum distances (in general, 30 cm)
from other devices.
If you observe a strange smoke, odor or noise from the instrument,
unplug the power cord immediately and turn off the main power switch.

Section 1
Warnings and Cautions
Ignoring the following cautions could cause injuries or property
damages.
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 your instrument 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.
Mechanical shock or vibration can damage this equipment. Pay extra
attention while moving it. Damages caused by mechanical shock or
vibration may result in injury or fire.
Do not impact the 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.

•Selection of the Temperature Control Modes
Three user-selectable temperature control modes are provided for
your convenience:
2-1

Section 2
General Description
Features (continued)
Optimal Mode
Providing optimal balance between the heat-up
time to reach the target temperature and the
allowed fluctuation range of temperature overshoot
and undershoot (factory default)
Fast Mode
Providing the fastest heat up time but wide
fluctuation range of temperature overshoot and
undershoot
Slow Mode
Providing the slowest heat up time but the
narrowest fluctuation range of temperature
overshoot and undershoot.
User Mode
Allowing linear heating up to the target temperature
using the maximum heating rate and switching on
and off the heater based on the target temperature.
Note that this mode shows the widest fluctuation
range of temperature overshoot and undershoot.
User Mode
Allowing the auto-tuned parameters to be used for
temperature control
•Adjustment of the Heating Rate
If needed, you can adjust the heating rate ranging from 0 to 100% at
1% intervals. [Refer to Temperature Setting (r mode) in Section 4.]
•Selection of the Timer Mode
Immediate Activation - The timer starts immediately after setting the
timer.
Delayed Activation -The timer is activated only when the set
temperature is reached.
•Auto-tuning (Calibration)
Automatic tuning of the PID parameters provides more accurate
temperature control. [Refer to Auto-tuning (PID Parameter
Calibration) in Section 4.]
•Temperature Offsetting
In case your own thermometer is to be used for temperature control
for specific applications, there can be some differences between the
temperature of your thermometer and the displayed temperature of
this unit. If needed, such temperature differences ranging from -10°C
to 50°C at 0.1°C interval can be offset. See Temperature Offsetting in
Section 4.

Section 2
General Description
Safety
•High and Low Temperature Limits
The high temperature limit of the top plate is set to 350°C to protect
you and your media. However, you can set your own high and low
temperature limits to reduce operation time and also to avoid
inadvertent mistakes.
If the temperature of the top plate exceeds the set temperature
range, the heater will be automatically turned on and off and the
Heater LED will be turned on and off accordingly.
•Multiple Overheat Prevention Measures
Built-in overheat prevention circuit will turn off the heater if the plate
temperature reaches 450°Cfor any reason. In addition, if the
temperature of the main body exceeds 85°C the overheat prevention
circuit also stops heating to protect the motor and the PCB. You will
be alerted by both audible and visible signals will be activated.
In such cases, turn off the power switch and disconnect the power
cord first. Allow your unit to cool down completely before operating it
again.
•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 equipment 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.
•Heating Bath (Patent Pending, , optional)
A specially designed non-slip heating bath shown above is
available. (optional) To prevent unintentional slips of the bath during
operation, this bath has concavo-convex bottom so that it fits
snuggly on top of the heating plate.

•Lock Button
Inadvertent or accidental changes during operation can be
prevented by using this feature.
•Transparent Shield
An optional transparent shield is available to allow you to monitor
your operations more safely by shielding you against liquid
splashes.
•Spill-proof Body Design
Spill-proof design of the main body protects the inner parts of the
equipment and the elevated control panel reduces the chances of
contact with liquid spills or leakage.
Convenience
•Two large digital displays on the control panel clearly show both set
and actual temperatures of the top plate side by side.
•Easily set your own temperature limit at any value between 0 and
350°C.
•Heating rate can be set from 0 to 100% at 1% interval for delicate
temperature control.
•Up to two support rods (optional) can be attached to hold various
kinds of devices such as temperature sensors, thermometers,
laboratory glassware, and so on.
•The ceramic-coated top plate is highly resistant to heat and corro-
sion. In addition, its white color is optimal for monitoring color
changes of the media during operation.

deactivated to maintain the set temperature.
•Hot Top Warning Indicator will illuminate if the top plate temperature
is over 50°C.
•Surface temperature may be hot!
•Even if the instrument is turned off, the surface of the top plate and
the vessel on top of it will remain very hot for some time. Never
leave your instrument accessible to others while it is hot and never
touch it unless you are absolutely sure.
