PRECAUTIONS FOR USE
These current probes comply with safety standards EN 61010-1, EN 61010-031,
and EN 61010-2-032 for voltages of 300V in Category IV or 600V Category III.
The protection obtained by the instrument can be compromised if it is used in a
way that is not recommended by the manufacturer.
■The operator and/or the responsible personnel 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.
■Do not use the clamp on networks at higher voltages or in higher categories
than those mentioned.
■Do not use the clamp if it appears to be damaged or incorrectly closed.
■Before each use, check the condition of the insulation on the leads and
housing. Any item of which the insulation is deteriorated (even partially) must
be set aside for repair or scrapping.
■ Always keep your ngers behind the physical safety guard.
■All troubleshooting and metrological checks must be performed by competent
and accredited personnel.

3. OPERATION
■Set the switch to the position to check the battery status. If the battery
indicator lights, the battery must be replaced (see §5.3).
■Set the switch to ON. The indicator lights.
■Connect the current probe to one of
the current inputs on the device.
■Turn the device ON.
■Adjust the zero by watching the
display of the device and turning the
zero adjustment knob until the device
displays 0.
■Open the jaws and clamp the
conductor carrying the current to be
measured. There must be only one
conductor in the jaws of the clamp.
