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 conditions 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 effect any measurement under environmental conditions beyond the limits

specified in paragraph 14.4.

Check that batteries are not weak and placed 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:

CAUTION

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

terminal.

Avoid to effect 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.


CAUTION

The symbol "

" shows the battery charge: When it is completely black the

battery are full charge, while the "

" symbol indicate weak batteries. When

the batteries are too low to execute the test the instrument will show a warning
message. In the 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.


1.4. 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

the storage instructions described at paragraph 14.4.
