 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 1 YEAR 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 retun 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 when 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.
