This multimeter complies with the EN 61010-1 safety standard on double
insulation for electronic measuring instruments.
IP 67 as per standard IEC 60529.
Symbols used on the instrument:
Warning: Risk of danger.
Refer to the user’s manual to find out about the
potential dangers and any action to be taken in order to
avoid them.
Earth Double insulated
If you use this instrument in a way which is not specified, the protection
provided may be compromised, thus endangering you.
The safety of any system includingthis instrument is the responsibility of the
assembler of the system.
This instrument has been designed for use indoors:
- in an environment with pollution level 2,
- at an altitude of less than 2000 m,
- at a temperature between 0°C and 50°C,
- with relative humidity < 80 % up to 35°C.
It can be used for measurements on the circuits of:
- Category III installations for voltages up to 1,000 V (AC or DC)
relative to earth.
- Category IV installations for voltages up to 600 V (AC or DC)
relative to earth.
-CAT III: Measurement category III corresponds to measurements
carried out on installations in buildings.
Example: measurements on switchboards, wiring, etc.
-CAT IV: Measurement category IV corresponds to the measurements
carried out on the source of low-voltage installations.
Example: meters and measurements on the safety devices protecting
against overcurrents, etc.
For safety reasons, only use suitable cords supplied with the instrument:
they comply with the EN 61010-031 standard. Before each use, make
sure that they are in perfect condition.
When the instrument is connected to the measuring circuits, never touch a
terminal which is not in use. Use only suitable accessories delivered with
the instrument or approved by the manufacturer.
If the measurement category of the accessory is different from that
of the instrument, the lowest category applies to the unit.
