8. 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!

8.1 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.

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.
8.4 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.
8.5 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.
8.6 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.
8.7 Battery replacement
If the battery is depleted and only a residual charge remains, the battery symbol appears on the display.
If this occurs the battery should be changed in order to ensure safe operation. The battery should only be
exchanged outside the Ex-area. When changing the battery make sure that only those batteries specied
in this manual are used (see point 7.1:Table with type-tested batteries). The use of different batteries is
strictly prohibited!
To open the battery compartment rst remove the leather case from the handle. The compartment can now
be opened. You can then remove and exchange the battery. When the battery has been replaced the leather
case must be retted over the handle.
- Pay attention to the correct polarity.
- Dispose of depleted batteries in an appropriate and environmentally friendly manner!
