Working Safely
Warning
To avoid electric shock and/or equipment damage, use caution
when connecting test leads to live components. The jaws of
alligator clips can create a short circuit between closely spaced
live parts. Avoid making connections to feeder conductors or
bus bars at elevated potentials. Whenever possible, make
connections to the output side of a circuit breaker, which can
provide better short circuit protection.
• Follow all legal requirements. Follow all instructions in the manuals. Obey
posted instructions.
• Never assume that a circuit is de-energized. Check it first.
• Always set up the measurement first, then connect the test leads to the
circuit.
• Use only test leads and test lead adapters supplied with the Fluke 43B
(or safety-designed equivalents as specified in the accessory list,
see Chapter 2 of the Users Manual).
• Never use adapters or test leads that have exposed metal parts or
insufficient voltage rating.
• Remove all test leads that are not in use.
• Make connections to the instrument first, before connecting leads to a live
circuit.
• Connect the ground lead first, then the voltage leads and the current probe.
Disconnect in reverse order.
• Route your test leads carefully.
