1 PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in compliance with the directives relevant to electronic
measuring instruments. For your safety and to prevent damaging the instrument, please
carefully follow the procedures described in this manual and read all notes preceded by
symbol with the utmost attention. Before and after carrying out the measurements,
carefully observe the following instructions:
CAUTION
•Do not carry out any measurements in case gas, explosive materials or
flammables are present, or in humid or dusty environments
•Do not carry out any measurement in case you find anomalies in the
instrument such as deformation, breaks, substance leaks, absence of
display on the screen, etc
•Keep the instrument steady during any measuring operation
•Do not use the instrument in environments with temperatures
exceeding the operating and storage limits specified in § 8.1.1 in order
not to damage it
•Only the accessories provided together with the instrument will guarantee
safety standards. They must be used only if in good conditions and
replaced with identical models, when necessary
•Check that the battery is correctly inserted
•Check that the LCD display gives indications consistent with the function
selected
•Do not direct the instrument at very high intensity radiation sources
(e.g. the sun) in order to prevent damaging the IR sensor
•Prevent hits or strong vibrations to keep the instrument from damage
•When bringing the instrument from a cold to a hot environment, leave it on
long enough for condensation water to evaporate
In this manual, and on the instrument, the following symbol is used:
Warning: observe the instructions given in this manual; improper use could
damage the instrument or its components.
1.1 DURING USE
CAUTION
•Failure to comply with the caution notes and/or instructions may damage
the instrument or be a source of danger for the operator.
•Use the instrument only in the temperature ranges indicated in § 8.1.1.
1.2 AFTER USE
When measurement is complete, switch off the instrument. If you expect not to use the
instrument for a long period, remove the battery.

3 PREPARATION FOR USE
3.1 INITIAL CHECKS
Before shipping, the instrument has been checked from an electric as well as mechanical
point of view. All possible precautions have been taken so that it is delivered undamaged.
However, we recommend generally checking the instrument in order to detect possible
damage suffered during transport. In case anomalies are found, immediately contact the
forwarding agent. We also recommend checking that the packaging contains all
components indicated in § 7.5. In case of discrepancy, please contact the Dealer. In case
the instrument should be returned, please follow the instructions given in § 9.
3.2 INSTRUMENT POWER SUPPLY

Setting Emissivity of the material
1. Touch item “Emissivity” to set the emissivity values of the item whose temperature
needs to be measured. In order to carry out accurate temperature measurements, it is
important to define the correct value of this parameter, which represents the ability of a
body to emit infrared radiation, according to the kind of material the measured object is
made of. Table 1 shows the emissivity values for the most common materials.
Emissivity takes values between 0 (mirror or perfectly reflecting surface) and 1
(perfectly radiating blackbody). Most of the painted or oxydized surfaces have an
emissivity value of approximately 0.95.
