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.

Note

: Any unauthorised prior repair or 

adjustment will automatically invalidate the 
warranty.

Returning an 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 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.
