must be pressed to perform a one-time measurement. Use independent means to verify whether circuits are
energised. Safe working practices must be observed.
The PE (protective earth) pre-test must be carried out before any other test.
If the PE pre-test fail, there may be high voltage present within the charging station and on the output terminals
and a risk of electric shock. Other tests must not be started until the fault is investigated and rectified.
If no voltage is present between the L and N of the terminals or between the L and N of the test connector
when the instrument is connected to the charging point in charging mode, this may be because the instrument’s
internal fuse has blown.
Disconnect from all other equipment before opening the fuse or battery compartments.
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.
Use only non-rechargeable cells as specified in the instructions.
Replacement cells must be of the type specified in the instructions. Observe the correct polarity
No user serviceable parts are inside the equipment. Refer repairs to Megger approved service centres.
At the end of the equipment’s life dispose of it according to local regulations for recycling. Do not dispose of this
equipment to landfill.
2.3 Test lead warnings:
Test leads, including crocodile clips, must be in good condition, clean, dry and free of broken or cracked
insulation. The lead set or its components must not be used if any part of it is damaged.
2.4 Measurement categories:
CAT IV - Measurement category IV: Equipment connected between the origin of the low-voltage mains supply and
distribution panel.
CAT III -Measurement category III: Equipment connected between the distribution panel and electrical outlets.
CAT II - Measurement category II: Equipment connected between the electrical outlets and user’s equipment.
Measurement equipment may be safely connected to circuits at the marked rating or lower. The connection rating is
that of the lowest rated component in the measurement circuit.
