1. PRECAUTIONS AND SAFETY MEASURES 

The instrument has been designed in compliance with directive IEC/EN61010-1 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: 

  Do not carry out any voltage or current measurement in humid environments. 

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

present, or in dusty environments. 

  Avoid contact with the circuit under test if no measurements are being carried out. 

  Avoid contact with exposed metal parts, with unused measuring probes, circuits, etc. 

  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. 

  Pay special attention when measuring voltages higher than 20V, since a risk of 

electrical shock exists 

 

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

 

 

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

 

 

High voltage danger: electrical shock hazard. 

 

 

Double-insulated meter 

 

1.1. PRELIMINARY 

INSTRUCTIONS 

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

  It can be used for 

VOLTAGE

 measurements on installations with measurement 

category CAT II 300V. For a definition of measurement categories, see § 1.4. 

  We recommend following the normal safety rules devised by the procedures for 

carrying out operations on live systems and using the prescribed PPE to protect the 
user against dangerous currents and the instrument against incorrect use. 

  Do not test circuits exceeding the specified current and voltage limits. 

  Check that the battery is correctly inserted. 

 

1.2. DURING 

USE 

Please carefully read the following recommendations and instructions: 

 

 

CAUTION 

 

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. 

 

  When the instrument is connected to the circuit under test, do not touch any unused 

terminal. 

  Don’t execute continuity test when external voltage is present. 

 

1.3. AFTER 

USE 

  If the instrument is not to be used for a long time, remove the batteries.
