DBCL130 Dry Block Temperature Calibrator
Introduction
The DBCL130 calibrator provides a safe, dry, constant temperature source for checking and calibrating
a wide range of temperature sensors, systems, indicators and thermometers. It 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 15 pounds/6.8
kilograms. The unit covers the temperature range from -25°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 -25°C/-13°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 ensure that the case remains safe enough to handle even at maximum operating temperatures. The
DBCL130 calibrator has been designed to comply with all relevant electromagnetic interference and
electrical safety regulations.

Warning
Warning:
HIGH TEMPERATURES ARE DANGEROUS
HIGH TEMPERATURES ARE DANGEROUS: They can cause serious burns to operators and ignite
combustible material. Omega Engineering 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 PROTECTIVE 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 Omega Engineering equipment must have available the relevant literature needed to
ensure their safety. It 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. If the equipment is used in a manner not specified by Omega Engineering, the protection
provided by the equipment to the operator may be impaired. All Omega Engineering units have been
designed to conform to international safety requirements. If 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 Omega Engineering 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

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 the model DBCL130 operates
on any mains voltage from 100 to 240VAC. However a properly rated mains cable should be
used based on the mains operating voltage used.
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.
Clean the heater block cavity out with
3.
shop or canned air to remove any
particulate. Next place the probe insert
into the heater block as shown using the
supplied insert extractor to minimize the
risk of damaging the heater block and/or
probe insert. Never place a hot insert into
a cold heater block or vice versa as the
insert may become jammed which will
damage both parts. Always use the insert
extractor to both install and remove the
probe insert.
4.
To prevent damage to the heater block,
insert, peltiers and PRT block sensor DO
NOT use the following in or around the
block;
Oil, Thermal grease, Water
Aluminum oxide sand,
Ceramic fiber insulation or Kaowool
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 entered a set temperature the unit will start to heat or cool to that value.
3. Once the process value 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 start at higher temperatures first and then work
down to lower ones. This will allow devices to be removed safely.
5. Use the main insert well for calibrating sensors and thermometers. The ¼” hole behind the
insert well is for holding your reference thermometer when performing comparison
calibrations. All calibrations should be performed in the probe insert.
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 2nd 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 2nd 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 1st key on the left twice for the value to be accepted.

Operation near ambient
For best results, to calibrate at a set point near ambient when cooling down from a higher temperature
set parameter (AL-1) 3 °C/5 °F higher than you room ambient. When heating up from a lower
temperature set (AL-1) 3 °C/5 °F lower than ambient. Access the AL-1 parameter by pressing the mode
button (2nd from the left).
Temperature scale conversion
To switch from C to F and vice versa press and hold
then select C or F under the d-U parameter.
Next press
to display SL-H parameter. Set this value to 266 for degrees F operation and 130 for
degrees C. Press
to display SL-L parameter, leave this value at -40 for both degrees C and F. Press
to exit.
Press
once and then
until the parameter CN5 is displayed. For this value when switching from
F to C divide the value shown by 1.8 and change it. For conversion from C to F multiply by 1.8 and
change. Adjusting calibration parameters is discussed below.
Calibration Adjustment using a reference thermometer
Use the following if you have a traceable reference thermometer and would like to adjust the calibration of the
DBCL130. Calibrations should be performed in a 3/16” or ¼” diameter insert and not the reference well.
Press the first button on the left and then the 2nd button from the left until the top line displays CN5. The initial
value shown is the default factory calibration and corresponds to the readings shown on the factory calibration
certificate.
CN5 is a calibration offset, low end adjustment. Example if your reference thermometer reads 0.5 and the
DBC130 display is indicating 0.0 then set the CN5 value to 0.5. Then press the first button on the left. The display
will correct to 0.5 and start to cool down so the block reading and your reference thermometer match. Adjust
parameter CNRt at high end temperatures to correct non-linearity or slope. When done press the button on the left
one time.
Operator maintenance
NOTE THAT THIS EQUIPMENT SHOULD ONLY BE DISMANTLED BY PROPERLY TRAINED
PERSONNEL. REMOVING THE FRONT OR REAR PANELS EXPOSES POTENTIALLY LETHAL
VOLTAGES. THERE ARE NO OPERATOR MAINTAINABLE PARTS WITHIN THE
EQUIPMENT.
In 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. Omega Engineering will accept no
responsibility for any damage to units that are improperly packed for shipment. If 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. Fuse: The unit is protected by a fuse. It should only be changed by suitably qualified
personnel. If the fuse blows persistently, a serious fault is indicated and you may need to
return the unit to your supplier for repair.
