1. SAFETY PRECAUTIONS AND PROCEDURES

This meter is in compliance with safety standards EN61557 and EN61010-1 related to electronic measuring instruments. 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 paragraph 6.2.1.

• 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 20V to avoid risk of electrical shocks.

The following symbols are used:

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

Double insulated meter.

DC or AC voltage or current.

1.1. PRELIMINARY

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

• It can be used for testing the phase sequence on installations of overvoltage CAT IV

300V and CAT III 600V to the ground.

• When using the instrument always respect the usual safety regulations aimed at protecting you against the dangerous electric currents and protecting the instrument against incorrect operations.

• Only the leads supplied with the instrument guarantee compliance with the safety standards in force. They must be in good conditions and, if necessary, replaced with identical ones.

• This instrument is not suitable for measurements of non sine wave voltage.

• Do not test or connect to any circuit exceeding the specified overload protection or

under environmental conditions exceeding the limits indicated in paragraphs 6.1.1 and

6.2.1.

1.2. DURING USE

We recommend carefully reading the following recommendations and instructions:

CAUTION

An improper use may damage the instrument and/or its components or injure the operator.
