REPAIR AND WARRANTY

The instrument contains static sensitive devices, and care must be taken in

handling the printed circuit board. If an instrument’s protection has been

impaired it should not be used, but sent for repair by suitably trained and

qualified personnel. The protection is likely to be impaired if for example;

it shows visible damage; fails to perform the intended measurements; has

been subjected to prolonged storage under unfavourable conditions, or

has been subjected to severe transport stresses.

NEW INSTRUMENTS ARE GUARANTEED FOR 3 YEARS FROM

THE DATE OF PURCHASE BY THE USER.

Note:

Any unauthorized prior repair or adjustment will automatically

invalidate the Warranty.

Returning and Instrument for Repair

If it is necessary to return an instrument for repair, a returns authorisation

number must first be obtained by contacting one of the addresses shown.

You will be asked to provide key information, such as the instrument serial

number and fault reported, before the number is issued. This will enable

the Service Department to prepare in advance for the receipt of your

instrument, and to provide the best possible service to you.

The returns authorisation number should be clearly marked on the

outside of the product packaging, and on any related correspondence.

The instrument should be sent, freight paid to the appropriate address. If

appropriate a copies of the original purchase invoice and of the packing

note, should be sent simultaneously by airmail to expedite clearance

through customs.

For instruments requiring repair outside the warranty period a repair

estimate will be submitted to the sender, if required, before work on the

instrument commences.

Approved Repair Companies

A number of independent instrument repair companies have been

authorised for repair work on most Megger instruments, using genuine

Megger spare parts. A list of approved companies is available from the UK

address shown on this page. Spare parts are also available.
