Prior to operation, check that the transmitter, receiver and any connection cables are in good
condition and not damaged. The meter must not be used if any damage is identified, Contact Megger
for repair.
The Cable Locator may only be used on systems complying with the nominal voltages indicated in the
technical data section.
Prior to use, ensure the instrument is functioning correctly, as described within this manual. Always
connect the transmitter line terminal first and then the neutral.
The “-” earth/neutral terminal of the transmitter must always be connected to the conductor under
test before the “+” line terminal.
If the RCD/RCBO protecting the circuit under test trips on connection of the transmitter, this indicates
that a fault current is already present within the circuit.
If the instrument is subjected to a high electro-magnetic field, this may impede the functionality of the
instrument.

Shows obvious signs of damage
Is not functioning correctly. The instrument should be removed from service and the fault
investigated
Has been stored for too long under unfavourable conditions
Has been subjected to excessive heat or mechanical stress during transport or storage
All relevant local statutory regulations must be adhered to when using this instrument
