Symbols - Ferve F-1880 Manual Del Usuario

* Before measuring current, check the meter's fuse and turn off power to the
circuit before connecting the meter to the circuit.
* 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.
* Use just one 6F22 battery, properly installed in the Meter's battery case, to
power the Meter.
* Replace the battery as soon as the battery indicator ( * ) appears. With a low
battery, the Meter might produce false readings that can lead to electric shock
and personal injury.
* Do not measure voltages above 1000V in Category III, or 600V in Category IV
installations.
* When in REL mode, the "REL" symbol is displayed. Caution must be used
because hazardous voltage may be present.
* Do not operate the Meter with the case (or part of the case) removed.

1.3 Instructions
* Remove test leads from the Meter before opening the Meter case or battery
cover.
* When servicing the Meter, use only specified replacement parts-
* 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 meter 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 equipment in
accordance with 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.
* 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.
* If the meter is not going to be used for a long time, take out the battery and do
not store the meter in high temperature or high humidity environment.
