1.1 Precautions and safety measures
Failure to comply with safety instructions can create a risk of electrical shock, fire, explosion and
destruction of the instrument of the installations. If the device is used other than as specified in this
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.
Use cables and accessories for voltage
according to IEC 61010-031 and measurement
categories at least equal to those of the
instrument. If not, an accessory of a lower
category reduces the category of the combined
mult accessory to that of the accessory.
Respect the environmental conditions of use.
Strictly comply with the fuse specifications.
Disconnect all cables before opening the fuse
access cover.
Do not modify the instrument and do not replace
components using equivalent parts. Repairs and
adjustments must be carried out by qualified,
approved personnel.
Replace the battery as soon as the
symbol appears on the display. Disconnect all
cables before opening the battery access cover.
Use personal protection equipment when
conditions require it.
Keep your hands and fingers away from the
unused terminals of the device. When handling
sensors or test probes, do not place fingers
beyond physical finger guard.
