Section 1 Warnings and Cautions
Ignoring the following warnings could cause serious injuries or 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 strange smoke, odor or noise from the instrument, unplug the
power cord immediately and turn off the main power switch. After the smoke or
odor disappears, contact your dealer or Thermo Scientific if any repair is
required.
Never disassemble, repair, or modify this equipment on your own. Doing so will
void your warranty and may result in injuries or product damages.

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. A damaged
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.
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 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.

2-2 Digital Hotplate Thermo Scientific
Section 2
General Description
Features Performance
• Microprocessor PID Feedback Control
Fast and precise temperature control is provided by the microprocessor
PID controller
• Quick Heat Up Time
Ample heating capacity and superb heat transfer rate of the tightly inte-
grated structure of heater and ceramic-coated aluminum alloy top plate
allow quick heat up time (up to 350°C).
• Selection of the Temperature Control Modes
Three user-selectable temperature control modes are provided for your
convenience:
• Adjustment of the Heating Rate
If needed, you can adjust the heating rate ranging from 0 to 100% at 1%
interval. (Refer to 4.2.4 Temperature Setting under Heating Rate Priority
Mode (r mode))
• 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 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.
User Mode Allowing the auto-tuned parameters to be used for temperature control
