Opening the
instrument
Digital Benchtop Multimeter
When performing current measurements, never change of
range, do not connect or disconnect leads without first isolating
the current. If you do, there is a risk of generating surge
currents, which can blow the fuses or damage the instrument.
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 type TV
filter will attenuate any such pulses.
Never perform resistance measurements on live circuits.
Make sure that you do not block ventilation.
Refer to user's manual.
Incorrect use can damage unit and be a safety hazard for user.

Before opening the instrument, always disconnect from all
sources of electric current and make sure not to be loaded with
static electricity, which may destroy internal components.
Fuses must be replaced with fuses of the same rating and type.
Any adjustment, maintenance or repair work carried out on the
multimeter while it is live should be carried out only by
appropriately qualified personnel. A "qualified person" is one
who is familiar with the installation, construction and operation of
the equipment and the hazards involved. He is trained and
authorized to energize, de-energize circuits and equipment in
accordance with established practices.
When the instrument is open, remember that some internal
capacitors can retain a dangerous potential even after the
instrument is powered down.
If any faults or abnormalities are observed, take the instrument
out of service and ensure that it cannot be used until it has been
checked out.
