1. SAFETY PRECAUTIONS AND PROCEDURES 

This instrument complies with safety Standards EN61557 and EN61010-1 related to electronic 
measuring instruments. 

 

 

 

CAUTION 

 

 

 

 

For your own safety and to avoid damaging the instrument follow the 
procedures described in this instruction manual and read carefully all notes 
preceded by this symbol 

.

 

 

When taking measurements: 

 

avoid doing that in humid or wet places - make sure that humidity is within the limits indicated in 
section “environmental conditions”. 

 

avoid doing that in rooms where explosive gas, combustible gas, steam or excessive dust is 
present. 

 

keep you insulated from the object under test. 

 

do not touch exposed metal parts such as test lead ends, sockets, fixing objects, circuits etc. 

 

avoid doing that if you notice anomalous conditions such as breakages, deformations, fractures, 
leakages of battery liquid, blind display etc. 

 

be particularly careful when measuring voltages exceeding 25V in particular places (building 
yards, swimming pools, etc.) and 50V in ordinary places to avoid risks of electrical shocks. 

 
The following symbols are used: 
 

 

CAUTION - refer to the instruction manual - an improper use may damage the 
instrument or its components 

 

 

 

DC voltage 

 

 

 

AC voltage 

 

1.1. PRELIMINARY 

INSTRUCTIONS 

 

This instrument has been designed for use in environments of pollution degree 2. 

 

It can be used for tests on electrical installations of overvoltage category III 265V and 550V 
maximum rated interlinked voltage (and to earth). 

 

You are recommended to respect the usual safety regulations aimed at protecting you against 
dangerous currents and protecting the instrument against improper use. 

 

Only the original test leads supplied along with the instrument guarantee compliance with the 
safety Standards in force. They must be in a good conditions and, if necessary, replaced with 
identical ones. 

 

Do not test nor connect to any circuit exceeding the specified overload protection. 

 

Do not take measurements under environmental conditions exceeding the limits indicated in this 
manual. 

 

Make sure that batteries are correctly installed. 

 

Before connecting the test probes to the installation make sure that the right function is chosen.
