Working environment

The calibrator units are designed to work safely under the following conditions:

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

HIGH TEMPERATURES ARE DANGEROUS: They can cause serious
material. Omega 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

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

After use, when you have finished heating samples, remember that parts of the unit may be very hot.
Take the precautions listed earlier.

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.

etting 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!
