Safety Instructions

1 Safety Instructions

This document contains important information, which should be kept at all times with the instrument
during its operational life. Other users of this instrument should be given these instructions with the
instrument. Eventual updates to this information must be added to the original document. The
instrument can only be operated by trained personnel in accordance with these instructions and local
safety regulations.

Acceptable Operation

This instrument is intended only for the measurement of temperature. The instrument is appropriate
for continuous use. The instrument operates reliably in demanding conditions, such as in high
environmental temperatures, as long as the documented technical specifications for all instrument
components are adhered to. Compliance with the operating instructions is necessary to ensure the
expected results.

Unacceptable Operation

The instrument should not be used for medical diagnosis.

Replacement Parts and Accessories

Use only original parts and accessories approved by the manufacturer. The use of other products can
compromise the operation safety and functionality of the instrument.

Instrument Disposal

Disposal of old instruments should be handled according to professional and
environmental regulations as electronic waste.

Operating Instructions

The following symbols are used to highlight essential safety information in the operation instructions:

Helpful information regarding the optimal use of the instrument.

Warnings concerning operation to avoid instrument damage and personal injury.

The instrument is equipped with a Class 2 laser. Class 2 lasers shine only within the visible
spectrum at an intensity of 1 mW. Looking directly into the laser beam can produce a
slight, temporary blinding effect, but does not result in physical injury or damage to the
eyes, even when the beam is magnified by optical aids. At any rate, closing the eye lids is
encouraged when eye contact is made with the laser beam. Pay attention to possible
reflections of the laser beam. The laser functions only to locate and mark surface
measurement targets. Do not aim the laser at people or animals.

Incorrect use of 110 / 230 V electrical systems can result in electrical hazards and personal
injury. All instrument parts supplied with electricity must be covered to prevent physical
contact and other hazards at all times.

Basics

3 Basics

3.1 Measurement of Infrared Temperature

Everything emits an amount of infrared radiation according to its surface temperature. The intensity of
the infrared radiation changes according to the temperature of the object. Depending on the material
and surface properties, the emitted radiation lies in a wavelength spectrum of approximately 1 to 20
µm. The intensity of the infrared radiation (”heat radiation”) is dependent on the material. For many
substances this material-dependent constant is known. It is referred to as ”emissivity value”, see
appendix, see section .9.2 Typical Emissivity Values, page 55.
Infrared thermometers are optical-electronic sensors. These sensors are able to detect ”radiation of
heat”. Infrared thermometers are made up of a lens, a spectral filter, a sensor, and an electronic signal­processing unit. The task of the spectral filter is to select the wavelength spectrum of interest. The sensor
converts the infrared radiation into an electrical parameter. The connected electronics generate electrical
signals for further analysis. As the intensity of the emitted infrared radiation is dependent on the
material, the required emissivity can be selected on the sensor.
The biggest advantage of the infrared thermometer is its ability to measure in the absence of contact.
Consequently, surface temperatures of moving or hard to reach objects can easily be measured.

3.2 Distance and Spot Size

The desired spot size on the target will determine the maximum measurement distance and the
necessary focus length of the optical module. To avoid erroneous readings the target spot size must
contain the entire field of view of the sensor. Consequently, the sensor must be positioned so the field
of view is the same as or smaller than the desired target size. For a list indicating the available focus
models and their parameters see Figure 2: Optical Diagrams page 11.

3.3 Ambient Temperature

The sensing head is designed for measurements in ambient temperatures between 0 and 70°C (32 to
158°F).

3.4 Atmospheric Quality

In order to prevent damage to the lens and erroneous readings, the lens should always be protected
from dust, smoke, fumes, and other contaminants. For this purpose an air purge collar is available. You
should only use oil free, clean “instrument“ air.

3.5 Electrical Interference

To minimize electrical or electromagnetic interference, follow these precautions:

 Mount the sensor as far away as possible from possible sources of interference such as

motorized equipment producing large step load changes.

 Ensure a fully insulated installation of the sensor (Avoid ground loops!).
 Make sure the shield wire in the sensor cable is earth grounded at one location.

3.6 Emissivity of Target Object

Determine the emissivity of the target object as described in appendix 9.1 Determination of Emissivity
page 55. If emissivity is low, measured results could be falsified by interfering infrared radiation from
background objects (such as heating systems, flames, fireclay bricks, etc. close beside or behind the
target object). This type of problem can occur when measuring reflecting surfaces and very thin
materials such as plastic films and glass.
This measuring error when measuring objects with low emissivity can be reduced to a minimum if
particular care is taken during installation, and the sensing head is shielded from these reflecting
radiation sources.

Put the following on the cable: the one of metal washers (4), the
relief bushing (6), the arc-plate (7) and the end nut (8).

Cut about 60 mm (2.3 in) of the cable sheath from the end of the
cable. Caution! Be careful! Do not cut into the shield!

Use another metal washer (3) to put the cable shield spread into
the two washers.

Clip the shield to fit the size of washers.

Strip 5 mm (.15 in) of insulation from the wires (6).
