SAFETY WARNINGS
Safety Warnings and precautions m u s t be read and
understood before the instrument is used. They m u s t
be observed during use.
The circuit under test must be de-energised and
isolated before Insulation, Resistance, or Continuity
tests are made.
During an insulation test, the circuit must not be
touched.
After insulation tests, capacitive circuits must be
allowed to discharge before disconnecting the test
leads.
Test leads, including prods and crocodile clips must
be in good order; clean, and with no broken or
cracked insulation.
Replacement fuses must be of the correct type and
rating.
BM 100/4 Only
U.K. Safety Authorities recommend the use of fused
test leads when measuring voltage on high energy
systems.
When making a voltage measurement, the 'Test' push
must not be pressed.
