Precautions and
safety measures
•
Read carefully all the notes preceded by the symbol .
•
If you use this instrument in a way which is not specified, the protection
which it provides may be compromised, putting you in danger.
•
The safety of any system incorporating this instrument is the responsibility of
the system assembler.
•
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 55°C
- with relative humidity of less than 80% up to 35°C.
•
It can be used for measurements on the following types of circuits:
- Measurement category III for voltages no higher than 1000 V
(AC or DC) in relation to the earth.
- Measurement category IV for voltages no higher than 600 V
(AC or DC) in relation to the earth.
Definition of
measurement
categories
CAT III: Measurement category III corresponds to measurements on building installations.
Example: measurements on distribution panels, cabling, etc.
CAT IV : Measurement category IV corresponds to measurements taken at the source of
low-voltage installations
Example: metering and measurements on overvoltage protection devices...
before use
•
Comply with environmental and storage conditions.
•
For your safety, only use the leads delivered with the instrument:
they comply with the norm EN 61010-1 (2001).
•
Before using it, systematically check that it is in perfect condition.
during use
•
Never exceed the protection limit values indicated in the specifications for
each type of measurement.
•
Before changing the function, disconnect the measurement leads from the
circuit measured.
•
Never measure resistances on a live circuit.
•
When the instrument is connected to the measurement circuits, never touch
an unused terminal.
As a safety measure, use only suitable leads and accessories supplied
with the instrument or approved by the manufacturer.
•
If the measurement category of the accessory is different from that of the
apparatus, the lowest category applies to the unit.
