PrECAUtIoNS for USE
This instrument and its accessories comply with safety standards IEC 61010-1, IEC 61010-031, and IEC 61010-2-030 for voltages
of 1000V in category IV at an altitude of less than 2000m, indoors, with a degree of pollution of not more than 2.
Failure to observe the safety instructions may result in electric shock, fire, explosion, and destruction of the instrument and of
the installations.
The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken
in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument.
If you use this instrument other than as specified, the protection it provides may be compromised, thereby endangering you.
Do not use the instrument on networks of which the voltage or category exceeds those mentioned.
Do not use the instrument if it seems to be damaged, incomplete, or poorly closed.
Before each use, check the condition of the insulation on the leads, housing, and accessories. Any item of which the insulation
is deteriorated (even partially) must be set aside for repair or scrapping.
Use only the leads and accessories supplied. Using leads (or accessories) of a lower voltage or category reduces the voltage
or category of the combined inst leads (or accessories) to that of the leads (or accessories).
Use personal protection equipment systematically.
Keep your hands away from the terminals of the instrument.
When handling the leads, test probes, and crocodile clips, keep your fingers behind the physical guard.
As a safety measure, and to avoid interference, do not move and do not handle the leads during measurements.
