USING AND MAINTENANCE
The probe user should note that the protection
provided by the equipment may be impaired,
if the equipment is used in a manner not
specified by the manufacturer.
To guarantee accurate performance
characteristics, machanical shocks should be
avoided, as well as damage to the cable
through excessive bending. Handle with care,
especially when the extra thin spring-tip is
fitted. All maintenance should be referred to
qualified personnel.
