• Auto-tuning (Calibration)
Automatic tuning of the PID parameters provides more accurate temper-
ature control. (Refer to 4.3.10 Auto-tuning (PID Parameter Calibration))
• Temperature Offsetting
In case your own thermometer is to be used for temperature control for
specific applications, there can be some differences between the tempera-
ture of your thermometer and the displayed temperature of this unit. If
needed, such temperature differences ranging from -10°C to ase°C at
0.1°C interval can be offset. Refer to section Temperature Offsetting.
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 tempera-
ture overshoot and undershoot
Slow Mode Providing the slowest heat up time but the narrowest fluctuation range of
temperature overshoot and undershoot
Point 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 tem-
perature. Note that this mode shows the widest fluctuation range of temper-
ature overshoot and undershoot.

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 tem-
perature 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 circum-
stances, 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)
A specially designed non-slip heating bath shown above is available as an
option. To prevent unintentional slips of the bath during operation, this
bath has concavo-convex bottom so that it fits snugly on top of the heat-
ing plate.
HOT TOP
Figure 2-1. Heating Bath

• 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 equip-
ment and the elevated control panel reduces the chances of contact with
liquid spills or leakage.
• Two large digital displays on the control panel clearly show both set
and actual temperatures of the top plate side by side.
• You can 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 corrosion.
In addition, its white color is optimal for monitoring color changes of
the media during operation.
