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.
