1 PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in accordance with the directives on electronic
measuring instruments. For your safety and to avoid damaging the instrument, please
follow the procedures described in this manual and read with particular care all the notes
preceded by the symbol . Before and during the execution of the measures follow these
indications:
ATTENTION
Do not carry out measurements in the presence of gases or explosive
materials, combustible or in humid or dusty environments
Do not make any measurements if anomalies are found in the instrument
such as deformations, breakages, leaks of substances, absence of display
on the display, etc.
Keep the instrument stable during each measurement operation
Do not use the instrument in environments with temperatures that
exceed the limits specified in § 7.1.1 in order not to damage it
Do not point the instrument at sources with high radiation intensity
(ex: sun) to avoid damage to the IR sensor
Avoid shocks or strong vibrations on the instrument to avoid damage
In the passage of the instrument from a cold environmental condition to a
very hot one, leave it on for a sufficient time for the evaporation of the
condensation effects
The following symbol is used in this manual and on the instrument:
Attention: follow the instructions in the manual; improper use could cause
damage to the instrument or its components.
