Instrument storage conditions: 

 

Temperature: -25...+55 °C. 

 

Humidity: less than 90 %RH no condensation. 

 

In storage, avoid places where: 

 

humidity is high; 

 

the instrument is exposed to direct sun radiation; 

 

the instrument is exposed to a high temperature source; 

 

high vibration levels are present; 

 

the instrument may be exposed to vapor, salt and/or corrosive gas. 

The housing of the instrument is in ABS plastic material: do not use solvents not com-
patible for cleaning.

SAFETY INSTRUCTIONS 

General safety instructions

 

The instrument has been manufactured and tested in accordance with the safety 
standard EN61010-1:2010 “Safety requirements for electrical equipment for mea-

surement, control and laboratory use” and has left the factory in perfect safety tech-
nical conditions. 
The instrument proper operation and operating safety can be ensured only if all stan-

dard safety measures as well as the specific measures described in this manual are 
followed.  
The instrument proper operation and operating safety can be ensured only in the cli-

matic conditions specified in this manual.  
Do not use the instruments in places where there are: 

 

Rapid ambient temperature variations that may cause condensation. 

 

Corrosive or flammable gases. 

 

Direct vibrations or shocks to the instrument. 

 

High-intensity electromagnetic fields, static electricity.  

If the instrument is moved from a cold environment to a hot one or vice versa, the 

formation of condensation might cause problems to its operation. In this case you 
need to wait for the instrument temperature to reach ambient temperature before op-
eration. 

User obligations 

The instrument operator shall follow the directives and regulations below that refer to 
the treatment of dangerous materials:  

 

EEC directives on workplace safety. 

 

National law regulations on workplace safety. 

 

Accident prevention regulations.
