3.1 - SAFETY PRECAUTIONS
Use of this multimeter implies respect for the usual safety rules
designed to protect the user against electrical hazards and to
protect the instrument against damage resulting from misuse.
The test leads and mains supply lead must be in good condition and
should be changed if there is any evidence of deterioration
(insulation burnt or split etc.). Only the leads supplied with the
instrument are guaranteed to meet safety standards. If necessary
they should be replaced by identical leads.
The maximum values indicated in these specifications should not
under any circumstances be exceeded.
Before opening up the instrument to replace the battery or fuses,
users must check that the test leads are disconnected from all
electrical current sources. Replacement fuses must be of the
same type and rating as the original fuses (see Specifications,
section 2.3).

If the order of magnitude of the quantity being measured is
unknown, begin with the highest range or select autoranging mode.
Disconnect the test leads from the circuit under test before
changing the measurement function. When measuring currents,
the range should not be changed and the leads should not be
plugged in or unplugged without first switching off the current.
