4. Functional description / operating instructions

Please read these operating instructions carefully so that you are familiar with, and are able to use, all of

the functions of your Ex-MP4 a. For your own safety and information please read through the instructions

on the following pages!

4.1 Mode of operation

All objects with a temperature above absolute zero radiate infrared energy, which extends in every direction

with the speed of light. If an infrared thermometer is trained on an object, the lens gathers the energy and

focuses it on an infrared sensor.

The sensor responds by emitting a voltage signal which is directly proportional to the absorbed energy. The

microprocessor-controlled electronics in the unit are able to ascertain and display the current temperature

(in regard to a wider parameter).

Objects with radiant or polished surfaces not only radiate energy but also reect a proportion of radia-

tion from their surrounding area. A factor between 0.1 and 1.0 designated as the emission level makes

allowances for this factual calculation so that only the true radiated energy, and not the reected energy, is

consulted for calculating the measured value. The majority of applications are measured with an emission

level of 0.95.

In the Ex-MP4 a the level is set at 0.95 and cannot be altered.

4.3 Optical diagram and field of sight

Distance sensor – object [mm]

Ensure that the specific area or object to be measured is

larger than the laser spot size of the device. The smaller

the object the closer the equipment must be. For opti-

mum measuring accuracy the area/object should be at

least twice that of the spot size.

4.4 Operation of the laser sight

The laser sight is a component of the Ex-MP4 a.

Please read through the following section carefully:

Warning! Do not stare directly at the laser!

Risk of eye damage!

Operate the unit carefully!

Do not aim the unit at other people!

The laser sight enables the unit to be aimed accurately and is useful for sighting small or distant objects.

However it does not indicate the size of the spot. This value is distance-dependent and can be inferred from

the optical diagram in this manual.

The units are equipped with a robust solid state laser which is housed inside the unit itself.

4.5 Operating the unit

°C deg / °F deg Change-over

In order to switch between centigrade and

fahrenheit, the battery compartment has to be opened – having

first taken off the leather case.

It is then possible to select the temperature

indicator required by sliding Switch A from either degree °C or

degree °F.

After selecting the temperature indicator required the leather

case must again be fitted before operation of the equipment in the

hazardous area.

The LCD indicator shows the temperature in degrees °C or

degrees °F. After release of the trigger the temperature measu-

rement is displayed for a further 7 seconds and at the same time

the word „Hold” is displayed. The battery condition indicator sym-

bol shows the state of the battery.

Operation of the Device

For a temperature reading, the equipment is

pointed towards an object and the trigger is pressed. Consider the distance

in relation to the spot size at this point (optical diagram) as well as taking

the eld of sight into consideration. With increased distance from the object,

increase the surface of the measured area of equipment.

(A)

4.6 Emission level

The majority of organic materials, as well as coated and oxidised surfaces, possess an emission level of

0.95. For this reason the emission level of the Ex-MP4 a has been set to 0.95 and cannot be altered.

When determining the temperatures of shiny or highly polished metallic surfaces inaccurate measure-

ments are produced. To compensate this effect the object being measured can be covered with adhesive

tape or coated with matt black paint. Wait until the adhesive tape is the same temperature as the underly-

ing material. Then determine the temperature of the tape (which is equivalent to the material) or the coated

surface.

In accordance with our general terms and conditions Pepperl+Fuchs SE provides a warranty for this

product for a period of two years regarding its function and material under the specied and permitted ope-

rating and maintenance conditions. This excludes all parts that are subject to wear and tear (e.g. batteries,

probes, calibration units, LEDs, etc.).

This warranty does not extend to products that are used improperly, have been modied, neglected, dama-

ged in accidents or exposed to abnormal operating conditions and inappropriate handling.

Any claims under the warranty can be invoked by returning the defective equipment to the manufacturer.

We reserve the right to repair, adjust or exchange the device.

The aforementioned warranty conditions are the sole and only right of the purchaser to compensation, are

exclusively valid and replace all other contract or legal warranty obligations. Pepperl+Fuchs SE assumes

no liability for special, direct, indirect, accompanying or consequential damage as well as losses including

unlawful action, action in good faith or any other action.

If the limitation of a legal warranty as well as the exclusion or limitation of accompanying or consequential

damage is not permissible in certain countries, it may be that the aforementioned limitations and exclu-

sions are not valid for every purchaser. Should any such clause of these warranty conditions be declared

ineffective or unenforceable by a competent court, then the effectiveness or enforceability of any of the

other conditions of these warranty conditions shall remain unaffected by such a judgement.

4. Funktionsbeschreibung / Bedienungshinweise

Bitte lesen Sie diese Bedienungsanleitung sorgfältig durch, damit Sie alle Funktionen Ihres Ex-MP4 a

kennen und nutzen können. Lesen Sie zu Ihrer Sicherheit und Information die Hinweise auf den folgenden

Seiten!

4.1 Arbeitsweise

Alle Objekte mit einer Temperatur über dem absoluten Nullpunkt strahlen infrarote Energie aus, welche

sich mit Lichtgeschwindigkeit in alle Richtungen ausbreitet. Wird ein Infrarot-Thermometer auf ein Mess-

objekt gerichtet, sammelt die Linse die Energie und fokussiert sie auf einem Infrarotsensor.

Der Sensor reagiert durch Ausgabe eines Spannungssignales, welches der aufgenommenen Energie direkt

proportional ist. Die mikroprozessorgesteuerte Elektronik des Gerätes ist in der Lage, unter Einbeziehung

weiterer Parameter, die momentane Temperatur zu ermitteln und anzuzeigen.

Messobjekte mit glänzender bzw. polierter Oberäche strahlen nicht nur Energie aus, sondern reektieren

auch einen Strahlungsanteil aus Ihrer Umgebung. Ein als Emissionsgrad bezeichneter Faktor zwischen 0,1

und 1,0 trägt dieser Tatsache Rechnung, so dass nur die wirklich abgestrahlte (und nicht die reektierte)

Energie zur Berechnung des Messwertes herangezogen wird. Der größte Teil aller Anwendungen ist mit

einem Emissionsgrad von 0,95 bemessen.

Beim Ex-MP4 a ist er deshalb auf 0,95 eingestellt und kann nicht verändert werden.
