7.1 Bluetooth

configuration

The Ex-MX4 BT allows data transfer via Bluetooth

System requirements:

- Windows-compatible computer (operating systems 98, ME, 2000, XP or higher).

- Bluetooth system completely installed on the computer (not included in the scope of

supply).

- Configuration software BlueTool (included in the supplied CD).

After installing the Bluetooth system on the computer, the thermometer can be ope-

rated in different modes (for the description of modes, refer to 8.7 Setup).

Please refer to the PDF files in the Bluetooth_Modul and BlueTool folders in the sup-

plied CD for information regarding the configuration of the LinTech Bluetooth module.

Please take the time to read through this operating manual carefully to ensure that you

are familiar with and can use all the functions of your Ex-MX4 BT. Please go through

the instructions on the following pages for your own safety and information!

All objects with a temperature above absolute zero radiate infrared energy that spreads

in all directions at the speed of light. If an infrared thermometer is aimed at a measure-

ment object, the lens gathers the energy and focuses it on an infrared sensor.

The sensor reacts by generating a voltage signal that is directly proportional to the

absorbed energy. The microprocessor-controlled electronic unit of the device can

determine and display the current temperature using additional parameters. Measure-

ment objects with a shiny or polished surface not only radiate energy, but also reflect a

part of the radiation from their surroundings.

An emissivity factor between 0.1 and 1.5 takes account of this fact so that only the

actually radiated (and not the reflected) energy is included in the calculation of the

measured value. The majority of applications are measured with an emissivity of 0.95.

It is therefore preset to 0.95 in our device and can be adjusted in steps of 0.01 depen-

ding on the application. Emissivity range over 1.00 is intended for applications, where

adjacent measurement objects having different temperatures are to be measured. For

example, this is the case if there are two conveying lines with different temperatures

and the temperature of ‚the colder one' is to be measured. The radiated reflected

energy would thereby falsify the measurement and hence a correct result would be

impossible. The temperature can now also be measured accurately using the emissivi-

ty setting > 1.00 by way of a one-time reference measurement using a contact thermo-

meter.
