Important instructions to read and to fully understand.

Useful information or tip to read.

The CE marking guarantees conformity with European directives and with regula-

tions covering EMC.

The trash can with a line through it means that in the European Union, the product

must undergo selective disposal for the recycling of electric and electronic material,

in compliance with Directive WEEE 2002/96/EC.

Denition of Measurement Categories (CAT)

CAT IV Measurement category IV corresponds to measurements taken at the

source of low-voltage installations.

Example: power feeders, counters and protection devices.

CAT III Measurement category III corresponds to measurements on building

installations.

Example: distribution panel, circuit-breakers, machines or xed

industrial devices.

CAT II Measurement category II corresponds to measurements taken on

circuits directly connected to low-voltage installations.

Example: power supply to domestic electrical appliances and portable

tools.

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.
