During use

∗
Never exceed the protection limit values indicated in the
specifications for each type of measurement.
∗
When the multimeter is linked to measurement circuits, do
not touch unused terminals.
∗
When the range of the value to be measured is unknown, check
that the range initially set on the multimeter is the highest possible
or, wherever possible, choose the autoranging mode.
∗
Before changing functions, disconnect the test leads from the
circuit under test.
∗
In TV repair work, or when carrying out measurements on power
switching circuits, remember that high amplitude voltage pulses at
the test points can damage the multimeter. Use of a TV filter will
attenuate any such pulses.
∗
Never perform resistance or continuty measurements on live
circuits.

Instructions

∗
Before opening up the instrument, always disconnect from all
sources of electric current and make sure you are not charged
with static electricity, which may destroy internal components.

Any adjustment, maintenance or repair work carried out on the
multimeter while it is live should be carried out only by
appropriately qualified personnel, after having taken into account
the instructions in this present manual.
∗
A "qualified person" is someone who is familiar with the
installation, construction and operation of the equipment and the
hazards involved. He is trained and authorized to energize and
de-energize circuits and
established practices.
∗
When the instrument is opened up, remember that some internal
capacitors can retain a dangerous potential even after the
instrument is switched off.
