SAFETY
WARNINGS
•
Safety Warnings and Precautions must be read and
understood before the instrument is used. They must be
observed during use.
•
The circuit under test must be de-energised and isolated
before connections are made except for voltage measurement.
•
Circuit connections must not be touched during a test.
•
After insulation tests, capacitive circuits must be allowed to
discharge before disconnecting the test leads.
•
The Live Circuit Warning and Automatic Discharge are additional
safety features and should not be regarded as a substitute for
normal safe working practice.
•
Replacement fuses must be of the correct type and rating.
Failure to fit the correctly rated fuse will result in damage to the
instrument in the event of an overload.
•
Test leads, including crocodile clips, must be in good order,
clean and have no broken or cracked insulation.
•
Ensure that hands remain behind guards of probes/clips when
testing.
•
U.K. Safety Authorities recommend the use of fused test leads
when measuring voltage on high energy systems.
