MIT400 and MIT2500 series safety warnings
National Health and Safety Legislation requires users of this equipment and their employers 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.
The voltage indicator and automatic discharge features must be regarded as additional safety features and not a
■
substitute for normal safe working practice which MUST be followed.
The circuit under test must be switched off, de-energized, securely isolated and proved dead before test connections
■
are made when carrying out insulation and continuity tests.
Test voltages greater than 1000V dc must not be used on capacitive circuits. Capacitive charges can be lethal.
■
Circuit connections greater than 15 nF, exposed-conductive-parts and other metalwork of an installation or equipment
■
under test must not be touched during testing.
The Voltmeter function will operate only if the instrument is switched on and working correctly.
■
After an insulation test, the instrument must be left connected until the circuit has been discharged to a safe voltage.
■
Do not handle test leads above the 1000 V range. (For use in dry conditions only).
■
The instrument should not be used if any part of it is damaged.
■
All test leads, probes and crocodile clips must be in good order, clean and with no broken or cracked insulation. Verify
■
the integrity of the test leads before making measurements. Only "Megger" approved test leads must be used with
this product.
Ensure that hands remain behind finger guards of probes/clips.
■
National Safety Authorities may recommend the use of fused test leads when measuring voltage on high-energy
■
systems.
Fused Leads must be tested independently before use to ensure fuse integrity.
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.
All covers must be in place whilst conducting tests.
■
If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment
■
may be impaired
The instrument must be used only by suitably trained and competent persons.
