The ThermCal130
Introduction
The ThermCal130 calibrator provides a safe, dry, constant temperature source for checking and calibrating a wide
range of temperature sensors, systems, indicators and thermometers. t is fast and economical and can be used
either on a bench top or as a portable field unit. The weight of the unit is only 17 pounds/7.7 kilograms. The unit
covers the temperature range from -20°C to +130°C in an ambient of 20°C using a machined aluminum block as
the heat transfer medium. The temperature control circuit is built into the unit.
Features include:
• Maximum temperature of 130°C/266°F
• Minimum temperature of -20°C/-4°F
• Up to eight setpoints can be stored & recalled
• insert well & ¼” diameter reference well
Even though the unit heats up and cools down rapidly, highly efficient insulation and an internal cooling fan
ensures that the case remains safe enough to handle even at maximum operating temperatures. The
ThermCal130 calibrator has been designed to comply with all relevant electromagnetic interference and electrical
safety regulations.

Ambient temperature range: 5°C/9°F to 40°C/104°F
Humidity: Up to 95% relative humidity, non-condensing
Warning
Warning: H GH TEMPERATURES ARE DANGEROUS
Aviso: LAS TEMPERATURAS ELEVADAS SON PEL
H GH TEMPERATURES ARE DANGEROUS: They can cause serious burns to operators and ignite combustible
material. Accurate Thermal Systems has taken great care in the design of these units to protect operators from
hazards, but operators should pay attention to the following points:
• USE CARE AND WEAR PROTECT VE GLOVES TO PROTECT HANDS
• DO NOT put hot objects on or near combustible objects
• DO NOT operate the unit close to inflammable liquids or gases
• DO NOT place any liquid directly in your unit
• At all times USE COMMON SENSE
Operator Safety
All operators of Accurate Thermal Systems equipment must have available the relevant literature needed to
ensure their safety. t is important that only suitably trained personnel operate this equipment in accordance with
the instructions contained in this manual and with general safety standards and procedures. f the equipment is
used in a manner not specified by Accurate Thermal Systems, the protection provided by the equipment to the
operator may be impaired. All Accurate Thermal Systems units have been designed to conform to international
safety requirements. f a safety problem is encountered, switch off at the power socket and remove the plug
from the supply. Please use caution when removing probes and inserts as burns to the skin can occur if in
contact.

Installation
1. All Accurate Thermal Systems units are supplied with a power cable.
2. Before connecting the power supply, check the voltage against the rating plate. Connect the power
cable to a suitable plug according to the table below. Note that the unit must be earth grounded
to ensure proper electrical safety.
Electrical connections:
220V-240V 110V-120V
Live Brown Black
Neutral Blue White
Earth ground Green/yellow Green
The fused plug supplied with the power lead for use in the UK is fitted with the following value fuse to
protect the cable: 230V UK 4 AMP
The fuse in the unit protects the unit and the operator
Note that units marked 230V on the rating plate work at 220V; units marked 120V work at 110V. n
both cases, however, the heating rate will degrade by approximately 8%. The rating plate is on the
rear of the unit.
3. Plug the power cable into the socket on the rear of the unit.
4. Place the unit on a suitable bench or flat workspace, or in a fume cupboard if required, ensuring that
the air inlet vents on the underside are free from obstruction.
After use, when you have finished heating samples, remember that parts of the unit may be very hot.
Take the precautions listed earlier.

OPERATION
Preparation
1. The heater design, temperature sensor and control circuit give good temperature control and
uniformity, but make sure that there is a close fit of the probes in the block to allow efficient heat
transfer. Contact us about an insert that more closely fits your probe or device being calibrated.
2. Plug the power cable into the socket in the back of the unit. Connect the power cable to the
electrical supply and switch the power on. 1 = power on, 0 = power off
Setting the operating temperature
1. To set the operating temperature required, press and hold either the up or down arrow button to
increment to the value required. Alternatively you can press the («PF) key to move over to
individual digits to set higher values much quicker. After 2 seconds your value will be set & retained.
2. When you have the correct set temperature displayed the unit will start to heat or cool to that
value.
3. Once the process value/actual temperature reaches the set point, allow the block to fully stabilize for
at least 10 minutes before performing a calibration.
4. When calibrating sensors and thermometers a best practice method is to start at higher
temperatures first and then work down to lower ones. This will allow devices to be removed safely.
Entering up to 8 setpoints for fast recall
1. To input up to 8 setpoints press the first button on the left and then the 2
nd
button from the left
until the top line displays SP-0. Here you can enter up to 8 values for fast future recall. Do not
change any of the settings or values after SP-7. When finished entering values press the button on
the left one time.
You’ll need to note which value is in which location for future recall.
2. To select one of the 8 setpoints for use from the main display press the 2
nd
button from the left so
the top line displays M-SP. Next use the up arrow key to select one of the 8 setpoint values. Press
the 1
st
key on the left twice for the value to be accepted.

Operation near ambient
For best results, to calibrate at a setpoint near ambient when cooling down from a higher temperature set
parameter (AL-1) 3 °C higher than you room ambient. When heating up from a lower temperature set (AL-1) 3 °C
lower than ambient. Access the AL-1 parameter by pressing the mode button (2
nd
from the left). Do not change
AL-2 which should be set at 1.0
Factory default control parameters
The parameters used in the controller have been developed by Accurate Thermal Systems to give the best unit
performance for most applications. f the need arises the “AT” autotune command can be run to further optimize
results based on the thermal block load and ambient conditions. Contact us for further support and details.
Switching the display from Degrees C to Degrees F and vice versa
To switch the display press and hold down the left key until the display indicates “CN-t”, next press the 2
nd
key
from the left one time and the top line will show “d-U” which is display units. Switch to either C or F. After setting
this value hold down the left most key so the controller resets and accepts the new value.
Next press the first button on the left and then the 2
nd
button from the left until the top line displays CN5.
Set CN5 to ____ for degrees F operation and ____ for degrees C. Unit S/N: _____________
When done press the button on the left one time.

n the unlikely event that you experience any problems with your unit which cannot easily be remedied, you
should contact your supplier and return the unit if necessary. Please include any details of the fault observed and
remember to return the unit in its original packing. Accurate Thermal Systems will accept no responsibility for any
damage to units that are improperly packed for shipment. f in doubt, contact your supplier.
1. Cleaning: Before cleaning your unit, ALWAYS disconnect it from the power supply and allow it to
cool to 30° C. Your unit can be cleaned by wiping with a damp soapy cloth. Care should be
exercised to prevent water from running inside the unit. Do not use abrasive cleaners.
2. Fuses: Your unit is protected by fuse. They should only be changed by suitably qualified
personnel. f the fuse blow persistently, a serious fault is indicated and you may need to return the
unit to your supplier for repair.
ADDITIONA INFORMATION
The controller is factory preset with all parameters and calibration data and therefore cannot be
calibrated or serviced in the field. Please contact Accurate Thermal Systems for arrangements to have
your unit calibrated or serviced.
