1  PRECAUTIONS AND SAFETY MEASURES 

In the whole manual, the word “instrument” generically indicates models 

THT60 

and 

THT70

, unless otherwise indicated. The instrument has been designed in compliance with 

the directives relevant to electronic measuring instruments. For your safety and in order to 
prevent damaging the instrument, please carefully follow the procedures described in this 
manual and read all notes preceded by the symbol 

 with the utmost attention. Before 

and after carrying out the measurements, carefully observe the following instructions: 

 

CAUTION 

 

x

  Do not carry out any measurements in case gas, explosive materials or 

flammables are present, or in humid or dusty environments. 

x

  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. 

x

  Keep the instrument steady during any measuring operation. 

x

  Do not carry out any measurements which exceed the working and storage 

temperature ranges specified in § 8.1.1. 

x

  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. 

x

  Check that the battery is correctly inserted. 

x

  Check that the LCD display gives indications consistent with the function 

selected. 

x

  Do not direct the instrument at very high intensity radiation sources (e.g. the 

sun) in order to prevent damaging the IR sensor. 

x

  Prevent hits or strong vibrations in order to keep the instrument from 

damage. 

x

  When bringing the instrument from a cold to a hot environment, leave it on 

long enough for condensation water to evaporate. 

x

  Only use the micro SD card provided with the instrument. 

 

In this manual, and on the instrument, the following symbols are used: 

 

 

Caution: observe the instructions given in this manual; improper use could 
damage the instrument or its components. 

 

 

This symbol on the display means that the instrument is able to emit a laser 
pointer in Class 2. 

Do not direct the radiation towards the eyes in order to 

prevent physical damage to people.

 

 

Compliant with European Standards 

 

 
1.1 DURING 

USE 

 

CAUTION 

 

x

  Failure to comply with the caution notes and/or instructions may damage 

the instrument and/or its components or be a source of danger for the 
operator. 

x

  Use the instrument only in the temperature ranges indicated in this manual. 

 
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.
