The laser sight is a component of the MasterEx 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.
The majority of organic materials, as well as coated and oxidised surfaces, possess an emission level of 0.95. For this reason the

When determining the temperatures of shiny or highly polished metallic surfaces inaccurate measurements 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 underlying material. Then determine the temperature of the tape (which is equivalent to
the material) or the coated surface.
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 specified 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 first 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 refitted over the handle.
- Pay attention to the correct polarity.
- Dispose of depleted batteries in an appropriate and environmentally friendly manner.

8.4 Operation of the laser sight

Cº deg / Fº 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 Cº or degree Fº (A).
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 Cº or degrees Fº. After
release of the trigger the temperature measurement is displayed for a further
7 seconds and at the same time the word "Hold" is displayed. The battery
condition indicator symbol 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 field of sight into consideration. With increased distance from the object, increase the
surface of the measured area of equipment.
Ex-MP4 a has been set to 0.95 and cannot be altered.
