SAFETY WARNINGS
■
Safety Warnings
and
Precautions
must be read and understood before the instrument is used. They
must
be observed during use.
■
Continuity of protective conductors and earthed equipotential bonding of new or modified installations
must
be verified
before
carrying out an earth
fault loop impedance or RCD tests.
■
Do not leave the instrument connected to the mains supply when not in use.
■
Circuit connections and exposed metalwork of an installation or equipment under test must not be touched.
■
Ensure that hands remain behind guards of probes/clips when testing.
■
The instrument should
not
be used if any part of it is damaged.
■
Test leads, probes and crocodile clips must be in good order, clean and with no broken or cracked insulation.
■
National Safety Authorities may recommend the use of fused test leads when measuring voltage on high-energy systems.
■
The battery cover
must
be in place whilst conducting tests.
■
Voltage indicator LED’s cannot reveal a N-PE supply reversal.
■
When making a 2 wire measurement with the 3 wire lead set, for safety reasons the balck test lead should be connected together with the green test lead.
2
Users of this equipment and/or their employers are reminded that Health and Safety Legislation requires them to carry out valid risk assessments of all
electrical work so as to identify potential sources of electrical danger and risk of electrical injury such as inadvertent short circuits.
Some national safety authorities recommend fused leads for voltage measurement on high energy systems. If RCD or Loop tests are made it may cause the
fuse to rupture, and so they must be used with caution on voltage testing.
NOTE
THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSONS.
