PRECAUTIONS FOR USE
This instrument is compliant with the NF EN 61010-1 + NF EN 61010-2-030 safety standard for 1000 V voltages in category
III or 600 V in category IV at an altitude below 2000 m, indoors, and with a maximum pollution level of 2.
Failure to comply with safety instructions can create a risk of electric shock, fire, explosion and destruction of the instrument
or the installations.
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 of as waste.
Use cables and accessories for voltages according to IEC 61010-031 and measurement categories at least equal to
those of the instrument.
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.
Do not place your hands close to instrument terminals that are in use.
When handling sensors or test probes, do not place fingers beyond the physical finger guard.
MEASUREMENT CATEGORIES
CAT II: Test and measurement circuits directly connected to points of use (power outlets and other similar points) on the
low-voltage network.
E.g. Measurements on circuits in network for household appliances, portable tools and other similar instruments.
CAT III: Test and measurement circuits connected to parts of the building's low-voltage network installation.
E.g. Measurements on distribution switchboards (including secondary meters), the circuit breakers, cabling including cables,
busbars, junction boxes, circuit breakers, power outlets in the fixed installation and industrial instruments and other
equipment such as motors permanently connected to the fixed installation
CAT IV: Test and measurement circuits connected to the source of the building's low-voltage network installation.
E.g. Measurement on equipment installed upstream of the main fuse or building installation cut-off switch.
