1.5 Impaired Safety

Whenever it is likely that safety has been impaired, the instrument must be turned off
and disconnected from line power. The matter should then be referred to qualified
technicians. Safety is likely to be impaired if, for example, the instrument fails to
perform the intended measurements or shows visible damage.

1.6 General Safety Information

The instrument shall be disconnected from all voltage sources before it is opened.
Capacitors inside the instrument can hold their charge even if the instrument has been
separated from all voltage sources.
Components which are important for the safety of the instrument may only be replaced
by components obtained through your local FLUKE organization. These parts are
indicated with an asterisk (*) in the List of Replaceable Parts, Chapter 8.
1-4
Removing the instrument covers or removing parts, except
those to which access can be gained by hand, is likely to
expose live parts and accessible terminals which can be
dangerous to life.
