REPAIR AND WARRANTY

The instrument circuit contains static sensitive devices, and

care must be taken in handling the printed circuit board. If the

protection of an instrument has been impaired it should not be

used, and be sent for repair by suitably trained and qualified

personnel. The protection is likely to be impaired if, for

example, the instrument shows visible damage, fails to perform

the intended measurements, has been subjected to prolonged

storage under unfavourable conditions, or has been exposed 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.
