Precautions and safety measurements
This device is designed for use:
- indoors,
- in an environment of pollution level 2,
- at an altitude below 2000m,
- at a temperature between 0°C and 40°C
- at a relative humidity below 80% up to 31°C.
It can be used for measurements on 300V CAT-I circuits and
can be supplied by a 300V CAT-II network.
Definition of the measurement categories
Overvoltage category II corresponds to devices intended to
be connected to building circuits. It applies both to equipment
connected via plugs and to equipment connected permanently.
English
Eg: Measurements made on the low-voltage supply circuits of
household appliances, hand tools, and similar equipment.
Overvoltage category III corresponds to equipment intended
to be incorporated in building circuits. This type of equipment
can include wall outlets, fuse boards, and some mains
installation control equipment. Eg: Distribution panels
(including secondary meters), disconnects, wiring, including
cables, busbars, junction boxes, disconnect switches, outlets
on the fixed installation, industrial devices, and other
equipment such as motors permanently connected to the fixed
installation.
Overvoltage category IV corresponds to equipment installed
at the point of entry or near the origin of a building's power
supply, between the entry into the building and the main
distribution frame. This type of equipment can include power
meters and primary overvoltage protection devices. Eg:
Measurements on systems installed upstream of the main
fuse or circuit-breaker of the electrical installation of a building.
Precautions before use
Observe the environmental and storage conditions.
Precautions during use
- Read attentively all notes preceded by the
- Connect the device to an outlet having an earthing
