Location of the conductor during measurement
Jaws
Protective non-slip guard
Green light indicating correct power supply
3-position on/off sliding switch
Hand-held parts
Fitted lead 1.5 m

Safety plugs Æ 4 mm

3.1/ SWITCHING ON

Set the sliding switch
1 mV/A). Correct operation is indicated by a green light
that the battery is in good condition.
If this green indicator does not come on when the clamp is switched
on, or goes out during the operation of the clampit is necessary to
replace the battery (see MAINTENANCE chapter).
3.2/ DC ZERO ADJUSTMENT
Ensure that the jaws
they do not enclose any conductor. Connect the clamp to your
measurement instrument set up according to the appropriate
voltage range then turn the rotative button
displayed on the measurement instrument.

3.3/ MEASUREMENT

After having switched on the clamp, connected it to the measurement
instrument on the appropriate range, and set the zero DC (see the
two paragraphs above), enclose the conductor to be measured
in the jaws of the clamp and closed it.
The value is displayed on the measurement instrument.
Depending on the sensitivity selected on the clamp and the range
of your measurement instrument, apply the conversion ratio to get
the value of the current.
On DC current measurement, ensure that the arrow located
on the external edge of the jaws corresponds to the direc-
tion of the current flowing in the conductor (source Þ receiver).
