SAFETY WARNINGS
n
Safety Warnings
and
Precautions must be read
and understood before the instrument is used. They
must
be observed during use.
n
The circuit under test must be switched off, de-energised and isolated
before
test connections are made when carrying out insulation and continuity
tests.
n
Circuit connections and exposed metalwork of an installation or equipment under test
must not
be touched.
n
The live circuit warning and automatic discharge are additional safety features which may fail and therefore
safe working practices must be
observed.
n
The voltage function will only work if the instrument is functional and switched on.
n
After insulation tests, capacitive circuits must be allowed to discharge
before
disconnecting test leads.
n
The instrument
should not
be used if any part of it is damaged.
n
Test leads, probes and crocodile clips must be in good order, clean and with no broken or cracked insulation.
n
Ensure that hands remain behind guards of probes/clips when testing.
n
National Safety Authorities may recommend the use of fused test leads when measuring voltage on high-energy systems.
n
Replacement fuses
must
be of the correct type and rating. Failure to fit the correctly rated fuse may result in a safety hazard and may cause damage to
the instrument in the event of an overload.
n
The battery cover
must
be in place whilst conducting tests.
n
The MIT310A is designed for use only in a controlled electromagnetic environment.
2
Users of this equipment and/or their employers are reminded that National 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. Where the assessments
show that the risk is significant then the use of fused test leads may be appropriate.
NOTE
THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSONS.
CAT II - Measurement category II: Equipment
connected between the electrical outlets and the
user’s equipment.
CAT III- Measurement category III: Equipment
connected between the distribution panel and
the electrical outlets.
CAT IV - Measurement category IV: Equipment
connected between the origin of the low-voltage
mains supply and the distribution panel.
