1.2. Protection mechanisms
This instrument is fitted with various protection mechanisms :
∗ Varistor protection for limiting transients of over 1100 V at the VΩ terminal,
particularly 6 kV pulse streams as defined by the French standard IEEE 587.
∗ A PTC (positive temperature coefficient) resistor protects against permanent
overvoltages of up to 600 V during resistance, capacitance, continuity and diode test
measurements. This protection is reset automatically after overload.
∗ Two HBC fuses provide protection up to 600 V during measurements of intensity
type.
∗ An IP protection rating of 40.
∗ Maximum protection beteen mA and 10 A input terminals : 500 V.
1.3. Safety mechanisms
∗ The battery unit cannot be accessed without first disconnecting the measuring leads.
∗ When measuring voltages above 24 V, the sign blinks
on the display.
∗ When measuring voltages above 10 A, the sign blinks
on the display and an
intermittent audible signal warns the user.
∗ If the maximum range is repeatedly exceeded, an intermittent audible signal warns
the user in volt (DC and AC+DC) and current (DC and AC+DC) functions.
1.4. Warranty
This equipment is warranted against any defects of manufacture or materials according to
the general conditions of sale.
During the warranty period (3 years), defective parts will be replaced, the manufacturer
reserving the right to repair or replace the product. In the event of the equipment being
returned to the distributor or to a local agency, carriage to the centre shall be payable by
the customer. The warranty does not cover the following :
1.
Repairs necessitated by misuse of the equipment or use in association wi
th
incompatible equipment.
2.
Modification of the equipment or any related software wi
thout the explicit authorization
of the manufacturer.
3.
Repairs necessitated by attempts to repair or maintain the product made by
a person
not approved by
the manufacturer.
4.
Adaptation to a specific application not provided for
in the specifications of the
equipment or the user manual.
5. Damage after a drop, a shock or flooding.
1.5.
Maintenance and metrological verification
Return your instrument to your distributor for any work to be done within or outside the
guarantee.
1.6. Unpacking - Repackaging
This equipment has been fully checked out mechanically and electrically before shipping.
All precautions have been taken to ensure that the instrument arrives at its destination
undamaged. However, it is advisable to carry out a rapid check for damage sustained in
shipping. If there is any evidence of damage, make this known immediately to the shipper.
* Should you need to return the multimeter, preferably use the original packaging and
indicate the r
easons as clearly as possible on an accompanying note.
