CAUTION
To avoid damages to the instrument:
- Remove the test leads from test circuit before
changing the measurement function.
- Never connect voltages above 600V DC or 600V
AC RMS.
- Never connect voltage to the input terminals when
the rotary switch is selected to measure resistance.
- Maximum input voltage in thermocouple: 60V DC or
24V RMS AC.
Use of the Proper Fuse
To avoid dangerous fires, use the correct fuse, of the
same type and specification of operation current and
voltage, as specified. The use of the fuse with different
specification or short-circuit the fuse socket is prohibit
and can cause extremely serious injury.

2. SAFETY INFORMATION
This manual contains information and warnings that
must be followed for operating the meter safely and
maintaining the meter in a safe operating condition.
In the case of any doubt regarding the integrity of the
instrument, make the multimeter unusable
immediately.
The protection provided by the meter may be impaired
if, for example:

Terms in this Manual
CAUTION
It identifies practices or conditions that could result in
damage to the instrument or the equipment in test.
WARNING
It identifies practices or conditions that could result in
personal injury or loss of life.
Terms in the Instrument
ATENTION: Refer to the manual.
DANGER: It indicates terminals where
dangerous voltages can be present.
WARNING
1. To avoid electric shock or damages to the
instrument, do not apply voltages above 600V DC
or AC RMS between input terminals of the
instrument.
2. Observe the proper safety precautions when working
with voltages above 60V DC or 30V AC RMS.
Such voltages can expose the user to dangerous
electric shocks.
3. Make sure that the test leads are in good conditions
of security.
