followed to ensure safe and reliable operation of the unit under the described condi-
tions. Failure to follow the information and instructions can have dangerous conse-
quences or may contravene applicable regulations.
Please take the time to carefully read through the owner’s manual before you start
using the unit.
In the event of any doubt or discrepancies (for example, due to translation or printing
errors), the German version of these operating instructions shall prevail.
3. Errors and load restrictions
If there is any risk that the safety or integrity of the unit has been compromised, the
unit must be taken out of operation immediately and removed from the Ex-area without
delay.
Action must be taken to prevent the device from being accidentally placed into opera-
tion again.
We recommend sending the unit to the manufacturer to be examined.
The safety and reliability of the unit may be at risk if, for example:
- Damage is visible on the housing
- The unit has been subjected to excessive loads for which it is not designed
- The unit has been improperly stored
- The unit has been damaged in transit
- Labels or markings on the unit are illegible
- Malfunctions occur
- Obvious measuring inaccuracies occur
- no more measurements are possible with the device
- Permitted tolerances or threshold values have been exceeded
4. Safety regulations
Persons using the unit must observe the standard safety regulations and read the
certificate to prevent incorrect operation or misuse of the unit.
The following additional safety regulations must also be observed:
- The unit must not be opened within the Ex-area.
- The batteries must only be changed outside the Ex-area.
- Additional or spare batteries must not be carried in the Ex-area.
- Only approved battery types may be used.
- In potentially explosive areas, the device may only be operated in its leather pouch.

24
During use, always make sure that the leather pouch is completely closed and
undamaged.
- Only accessories approved by ecom instruments GmbH may be used.
- Avoid using the unit in aggressive acidic or alkaline solutions.
- Ensure that the unit is not taken into Zone 0 areas.
4.1 Special conditions for use in Zone 0 areas
Temperature measurement with the Ex-MX2 is only allowed within Zone 0 only if the
following conditions are met:
1. The Ex-MX2 temperature measuring device itself must not be brought into Zone 0.
2. Absolutely ensure that the device cannot fall into Zone 0, even by mistake. To ensu-
re this, the device’s carrying sling must also be attached securely to the operator’s
belt or to a belt loop.
The length of the carrying sling should be measured so that the Ex-MX2 still
maintains a distance of 50 cm to the boundary area of Zone 0 when it hangs freely
on the carrying sling.
Only the accessories approved by ecom instruments GmbH may be used.

8. Functional description / operating information
Please take the time to carefully read through these operating instructions to ensure
that you are familiar with and can use all the functions on your Ex-MX2. For your own
safety and information please read through the information on the following pages.
8.1 Operation
All objects with a temperature above absolute zero radiate infrared energy which spreads
in all directions at the speed of light. If an infrared thermometer is aimed at a measure-
ment object, the lens collects the energy and focuses it on an infrared sensor.
The sensor reacts by outputting a voltage signal which is directly proportional to the
absorbed energy. U(sing additional parameters, the microprocessor-controlled electro-
nics of the device are able to determine and display the current temperature. Measu-
rement objects with a shiny or polished surface do 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 re-
ally radiated (and not the reflected) energy is included in the calculation of the measu-
red value. The majority of all applications are measured with emissivity of 0.95.
It is therefore preset to 0.95 in our machine and can be adjusted depending on the ap-
plication in steps of 0.01. The emissivity range greater than 1.00 is intended for applicati-
ons where measurement objects close to each other with different temperatures should
be measured. This is the case for example if there are two conveying lines with different
temperatures and the temperature of „the colder one“ of both should be measured.
The radiated reflected energy thereby would falsify the measurement so that a correct
result would be impossible. The temperature can now also be measured exactly using
the emissivity setting >1.00 by means of a one-time reference measurement with a
contact thermometer.

8.4.1 Emissivity
Most organic materials and lacquered and oxidised surfaces have an emissivity of 0.95.
The emissivity is preset to 0.95 in the Ex-MX2 for this reason, but can be changed with
the rocker switch.
The determination of the temperatures of shiny or highly polished metal surfaces pro-
duces inaccurate measured values. To compensate for this, the surface to be measu-
red can be covered with adhesive tape or painted matt black. Wait until the adhesive
tape is the same temperature as the material underneath it. Then determine the tempe-
rature of the adhesive tape (corresponds to the material) or the painted surface.

8.4.2 Hl alarm
The Ex-MX2 provides an alarm function for exceeding defined temperature values. By
pressing the ENTER key, the alarm value can be set afterwards with the rocker switch.
The temperature values can be moved through in large steps by keeping the rocker
switch pressed. After confirming with the ENTER key, if the measured value is excee-
ded, an alarm signal sounds, the LED above the display lights and the laser marking
flashes. The default value is 50°C.
8.5 Measurement
The device is aimed at an object and the measurement button pressed to determine
the temperature. Remember to take account of the ratio of the distance to the spot size
(8.5.2 Optic diagram) and the field of view. The area of the surface measured by the
device increases as the distance between the device and the object increases.
8.5.1 Laser sighting
Laser sighting is part of the Ex-MX2, The laser sight allows very precise targeting and
is indispensable for sighting on small or far away objects. The 3 point laser marking
shows the exact size of the measuring spot. The equipment is equipped with a robust
solid-state laser which is installed inside the device.
Please read Section 5 Safety instructions carefully for information about laser warnings.

Distance m 0 1.15 1.50 2.50 3.00
8.5.3 Field of view
Ensure that the measuring object is larger than the size of the measuring
spot of the device. The smaller the measuring object the closer you
must approach the object. If the measurement accuracy is
crucially important, the measuring object should be at
least twice as large as the size of the measuring spot.
9. Changing the battery
If the battery is discharged and only a reserve operating time remains, the battery
symbol appears on the display. The battery should be replaced afterwards in order to
ensure safe operation.
The battery must only be changed outside the Ex-zone. When changing the battery,
it must be ensured that only the batteries listed in the operating instructions are
used. The use of other batteries is strictly forbidden.
You must remove the leather holster to open the battery
compartment. The battery compartment can now be opened.
Replace the used batteries and absolutely ensure that the
polarity is correct. After replacement, the leather holster
must be put on again as this is necessary for use in the
Ex-area.
- Always replace all of the batteries together.
- Make sure that the polarity of the inserted batteries is
correct.
- Please ensure that all used batteries are properly
disposed of in an environmentally friendly manner.
