During Use - Ferve F-1880 Manual Del Usuario

CAT IV Three-phase at utility connection, any outdoor conductors
• Refers to the "origin of installation"; i.e., where low-voltage connection is
made to utility power.
• Electricity meters, primary over current protection equipment.
• Outside and service entrance, service drop from pole to building, run
between meter and panel.
• Overhead line to detached building , underground line to well pump.
* When using this multimeter, the user must observe all normal safety rules
concerning:
-protection against the dangers of electric current.
-protection of the multimeter against misuse.
* For your own safety, only use the test probes supplied with the instrument,
Before use, check that they are in good condition.

1.1.2 During use

* If the meter is used near noise generating equipment, be aware that display
may become unstable or indicate large errors.
* Do not use the meter or test leads if they look damaged.
* Use the meter only as specified in this manual; otherwise, the protection
provided by the meter may be impaired.
* Use extreme caution when working around bare conductors or bus bars.
* Do not operate the meter around explosive gas, vapour, or dust.
* Verify a Meter's operation by measuring a known voltage. Do not use the
Meter if it operates abnormally. Protection may be impaired. When in doubt,
have the Meter serviced.
* Uses the proper terminals, function, and range for your measurements.
* When the range of the value to be measured is unknown, check that the range
initially set on the multi meter is the highest possible or, wherever possible,
choose the auto ranging mode.
* To avoid damages to the instrument, do not exceed the maximum limits of the
input values shown in the technical specification tables.
* When the multimeter is linked to measurement circuits, do not touch unused
terminals.
* Caution when working with voltages above 60Vdc or 30Vac rms. Such
voltages pose a shock hazard.
* When using the probes, keep your fingers behind the finger guards.
* When making connections, connect the common test lead before connecting
the live test lead; when disconnecting, disconnect the live test lead before
disconnecting the common test lead.
* Before changing functions, disconnect the test leads from the circuit under
test.
* For all dc functions, including manual or auto-ranging, to avoid the risk of
shock due to possible improper reading, verify the presence of any ac voltages
by first using the ac function. Then select a dc voltage range equal to or
greater than the ac range.
* Disconnect circuits power and discharge all high-voltage capacitors before
testing resistance, continuity, diodes, or capacitance.
* Never perform resistance or continuity measurements on live circuits.
