Please keep to the usual safety standards aimed at:
♦ Protecting against dangerous currents;
♦ Protecting the instrument against incorrect operations.
Only the accessories supplied with the instrument guarantee compliance with the
safety standards. Accordingly, they must be in good condition and, if necessary, they
must be replaced with identical models.
Do not take measurements on circuits exceeding the specified current and voltage
limits.
Before connecting cables, crocodiles and clamps to the circuit under test, make sure
that the right function has been selected.
Do not take any measurements under environmental conditions beyond the limits
specified in paragraph 14.4.
Check that batteries are not weak and inserted correctly.
Before connecting test leads to the circuit under test, check that rotary switch position
is correct.
1.3.
DURING USE
Please read carefully the following recommendations and instructions:
No compliance with the Warnings and/or Instructions may damage the
apparatus and/or its components or injure the operator.
Before selecting any function disconnect the test leads from the circuit under test.
When the instrument is connected to the circuit under test do not touch any unused
terminals.
Avoid taking resistance measurements in the presence of external voltages; even
though the instrument is protected, a too high voltage may cause malfunctions.
When measuring current, other currents located near the leads may affect the
measuring accuracy.
When measuring current, always position the wire in the very middle of the jaws in
order to obtain the highest accuracy.
A measured value remains constant if the "HOLD" function is active. Should you notice
that the measured value remains unchanged, disable the "HOLD" function.

When the batteries are too low to execute the test the instrument will show a
warning message. In this case interrupt testing and replace batteries following
the procedure described under paragraph 13.2. The instrument is capable of
keeping the data stored even though batteries are not installed. The
Instrument Date and Time settings aren't lost if you change the batteries
within 24hours.

AFTER USE
• After use, turn off the instrument by pressing ON/OFF for a few seconds.
• Remove batteries when the apparatus remains unused for long periods. Please follow
