Safety warnings
These safety warnings are indicative of safe practice and must be followed.
Additionally, they do not replace local safety procedures in the region where the instrument is used.
These safety warnings must be read and understood before the instrument is used. Retain for future reference.
This instrument must be operated only by suitably trained and competent people. Protection provided by the
instrument, test leads or probes may be impaired if they are not used in a manner specified by the manufacturer.
„ Local Health and Safety Legislation requires users of this equipment and their employers to carry out valid risk
assessments of all electrical work to identify potential sources of 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.
„ Replacement fuses must be of the correct type and rating. Failure to fit the correctly rated fuse will result in fire
hazards and damage the instrument in the event of an overload.
„ Do not operate the instrument or connect it to any external system if it shows visible signs of damage or if it has
been stored for prolonged time in an environment outside its specification.
„ This product is not intrinsically safe. Do not use in an explosive atmosphere.
„ 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.
„ 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 test.
„ After an insulation test, the instrument must be left connected until the circuit has been discharged to
a safe voltage.
„ Do not touch circuit connections and exposed metalwork of an installation or equipment under test.
Under fault conditions the system earth could become hazardous live.
„ Do not touch the earth stakes, test leads, or their terminations (including connections to the earthing system under
test) if an installation earth fault can arise, unless adequate precautions are taken.
„ The Voltmeter function will operate only if the instrument is switched on and working correctly.
„ The 'live circuit warning' and 'automatic discharge' features must be regarded as additional safety features and not
a substitute for normal safe working practice which MUST be followed.
„ Only Megger approved test leads must be used with this product.
„ 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 use.
„ The mains test lead provided with the instrument must only be used by suitably trained and competent persons.
Never connect test probes, pins or other objects to the three lead plugs because of the danger of electrocution and
arc explosion.
„ Ensure that hands remain behind guards of probes/clips when testing.
„ Always disconnect test leads from instrument and power down the instrument before disconnecting
the battery module.
„ The battery module must be replaced in a clean and dry environment.
„ Do not heat or dispose of the battery in a fire. Do not subject the battery to strong impact, mechanical shock or
excessive heat.
„ Do not short-circuit or reverse the polarity of the battery module.
„ Ensure every cell in the AA battery module is of identical type, and inserted in the correct orientation.
Never mix rechargeable and non-chargeable cells.
„ The instrument must be set to OFF before the instrument is prepared for shipping purposes.
„ The fuse cover located under the battery module must be fitted correctly before connecting the battery module or
protection will be compromised.
„ There are no user serviceable parts inside the instrument. Other than opening the fuse cover for the purpose of
replacing the fuses and performing firmware upgrades, do not disassemble the instrument.
