Impaired Safety; General Safety Information - Philips SCOPEMETER PM93 Service Manual

1 - 2 SAFETY INSTRUCTIONS
1.5 IMPAIRED SAFETY
Whenever it is likely that safety has been impaired, the instrument must be turned off and
disconnected from all external voltage sources, and the batteries must be removed. 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
WARNING: 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.
The instrument must be disconnected from all voltage sources and batteries must be removed before
it is opened.
Capacitors inside the instrument can hold their charge even if the instrument has been separated
from all voltage sources and batteries are removed. Components which are important for the safety
of the instrument may only be replaced by components obtained through your local FLUKE/PHILIPS
organization. These components are indicated by an asterisk (*) in the parts list section (chapter 9).
