THE UCAL 400+

Introduction

Techne’s UCAL400+ calibrator heater provides a safe, dry, constant temperature source. 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 nine pounds/four
kilograms. The unit covers the temperature range from 5°C above ambient up to 430°C using a machined
aluminum insert block as the heat transfer medium. The temperature control circuit is built into the unit.

Features include:

• 10 insert formats available

• Maximum temperature of 430°C/806°F

• An independent over-temperature cutout

• Temperature sensor burnout protection

Even though the unit heats up rapidly, highly efficient insulation ensures that the case remains cool enough to
handle even at maximum operating temperatures. Techne’s calibrator has been designed to comply with all
relevant Radio Frequency 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: HIGH TEMPERATURES ARE DANGEROUS
Avertissement: DANGER DE TEMPERATURES ELEVEES
Warnung: HOHE TEMPERATUREN SIND GEFÄHRLICH
Aviso: LAS TEMPERATURAS ELEVADAS SON PELI

HIGH TEMPERATURES ARE DANGEROUS: They can cause serious burns to operators and ignite combustible
material. Techne 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 Techne® 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 Techne, the protection provided by the equipment to the operator may be impaired. All Techne
units have been designed to conform to international safety requirements and are fitted with a preset over­temperature cutout. If a safety problem is encountered, switch off at the mains socket and remove the plug from
the supply.

Installation

1. All Techne units are supplied with a power cable.

2. Before connecting the mains supply, check the voltage against the rating plate. Connect the mains

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:

Live Brown Black
Neutral Blue White
Earth ground Green/yellow Green

The fused plug supplied with the mains 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. In
both cases, however, the heating rate will degrade by approximately 8%. The rating plate is on the
rear of the unit.

3. Plug the mains 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.

220V-240V 110V-120V

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.

2. Plug the power cable into the socket in the back of the unit. Connect the mains cable to the

electricity supply.

Setting the operating temperature

1. To set the temperature required, press and hold either the up or down button depending on the

direction you need to take the set point.

2. When you have the correct set temperature displayed, release the up or down button and the unit

will start to heat or cool to the set point.

3. Once the process value/actual temperature reaches the set point, allow the block to stabilize for 15

minutes before performing a calibration.

4. The controller is factory pre-set and only the set-temperature should be changed.

THE CONTROLLER MUST NOT BE SET TO CONTROL ABOVE 430°C/806°F OR DAMAGE TO THE UNIT
MAY RESULT.

After use

1. When you have finished calibrating, remember that parts of the unit and the probe may be very hot,

so precautions should be taken to prevent injury.

2. For safety, set the set temperature and allow the unit to cool to below 50°C/122°F before placing

the unit in a carrying case or shipping carton.

Changing from °C to °F

The controller is preset to display/operate in degrees C; however it may be changed to read in Degrees F. Refer
to section 5-2 of the 2216E Eurotherm Controller manual for instructions on changing from

Be careful not to change any of the other settings in the configuration menu as performance will be
affected and/or damage to the unit will occur!

THE FRONT OR REAR PANELS EXPOSES POTENTIALLY LETHAL MAINS 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. Techne will accept no responsibility for any damage to units
that are improperly packed for shipment. If in doubt, contact your supplier. See the Decontamination Certificate
supplied with your unit.

Cleaning: Before cleaning your unit, ALWAYS disconnect it from the power supply and allow it to

1.

cool below 50° 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.

Fuses: Your unit is protected by two fuses. They should only be changed by suitably qualified

2.

personnel. If the fuses blow persistently, a serious fault is indicated and you may need to return the
unit to your supplier for repair.
