Precautions And Safety Measures; Preliminary Instructions - HT PVCHECKs-PRO User Manual

1. PRECAUTIONS AND SAFETY MEASURES

The instrument has been designed in compliance with directive IEC/EN61010-1 relevant to
electronic measuring instruments. Before and while carrying out measurements, observe
the following indications and read all notes preceded by the symbol
attention.
 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 any contact with the circuit being measured if no measurements are being
carried out.
 Avoid contact with exposed metal parts, with unused measuring probes, etc.
 Do not carry out any measurement in case you find anomalies in the instrument such
as deformation, breaks, absence of display on the screen, etc.
 Pay special attention when measuring voltages higher than 25V in special
environments and 50V in normal environments, 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; improper use could
damage the instrument or its components.

PRELIMINARY INSTRUCTIONS

 The instrument has been designed to be used in the environmental conditions
specified in § 10.3. The presence of significantly different environmental
conditions can compromise the safety of the instrument and the operator. In any
case, before using, wait until the conditions inside the instrument are
comparable to the conditions of the environment in which it is operating
 The instrument may be used for measuring VOLTAGE and CURRENT in CAT III
1500V DC, CAT III 1000VAC with maximum voltage 1500VDC and 1000V AC between
inputs. Do not use on circuits exceeding the limit values specified in § 10.1
 We recommend following the normal safety rules devised to protect the user against
dangerous currents and the instrument against incorrect use.
 Only the accessories provided together with the instrument will guarantee safety
standards. They must be in good conditions and replaced with identical models, when
necessary.
 Make sure that batteries are correctly installed.
 Before connecting the measuring cables to the circuit being measured, check that the
desired function has been selected.
