manual, the protection provided by the device may be impaired.
The operator and/or the responsible authority
must carefully read and clearly understand the
various precautions to be taken in use.
Before using the instrument, make sure it works
properly when measuring a known voltage, and
check continuity by short circuiting both test
leads.
Do not use the instrument in an explosive
atmosphere or in the presence of inflammable
gas or smoke.
Do not use the instrument on networks with a
rated voltage or category higher than those
mentioned.
Respect the maximum rated voltages and
currents between terminals and in relation to the
earth.
Do not use the instrument if it seems damaged,
incomplete or incorrectly closed
Before each use, check the condition of the
cable insulation, the unit and the accessories.
All elements on which the insulation is damaged
(even partially) must be put out of service for
repair or disposed at waste.
