current sensor as per IEC 61010-2-032.
Equipment protected by double insulation.
The CE marking indicates conformity with European directives, in particular LVD and EMC.
The rubbish bin with a line through it indicates that, in the European Union, the product must
undergo selective disposal in compliance with Directive WEEE 2002/96/EC.
SAFETY PRECAUTIONS
Only use the PAC 11 clamp indoors.
Do not expose the clamp to running water.
Do not use the PAC 11 clamp on uninsulated conductors at a voltage of more than 600 V in relation
to the earth.
For measurements on DC current, check zero output. Adjust if necessary (see “Operating procedure”).
During measurement, ensure that the conductor is in line with the markings on the jaws and that the
clamp closes correctly.
Your clamp is supplied with a set of adhesive labels. Choose the label for your language and stick it
to the back of the case.

1. PRESENTATION
The PAC 11 current clamp measures DC or AC currents, without opening the circuit they are owing in.
The current clamp is used as an accessory for multimeters, recorders, etc.
This clamp measures DC currents up to 600 A and AC currents up to 400 A rms (600 A peak). It outputs
the form and amplitude of the current measured as a voltage image of the primary current.
The clamp has two ranges, 40 A (sensitivity 10 mV/A) and 400 A (sensitivity 1 mV/A), a zero adjust push
button, auto off feature to economise the battery power supply and two light indicators, one for faults
(over-range / incorrect zero reset), the other for power supply.
2. DESCRIPTION
See descriptive diagram at the end of the User Manual.
➀ Passage of the conductor
➁ Jaws
➂ Protective non-slip guard
➃ Automatic zero DC button
➄ Red fault light (over range / incorrect zero adjustment)
➅ Green light indicating correct power supply
➆ 3-position sliding switch (off / selection of 1 mV/A or 10 mV/A ranges)
➇ Hand-held parts
➈ Fitted lead 1.5 m
➉ Safety plug Ø 4 mm
3. OPERATING PROCEDURE
3.1. SWITCHING ON
Set the sliding switch ➆ to the appropriate position, 40 A range (sensitivity 10 mV/A) or 400 A range
(sensitivity 1 mV/A). Correct operation is indicated by a green light ➅ indicating that the battery is in
good condition.
After approximately 10 minutes of operation of the clamp without manipulation of the control buttons, the
power supply cuts off automatically (see “ Auto off ” below).
If this green indicator does not come on when the clamp is switched on, or goes out before it has operated
for 10 minutes, it is necessary to replace the battery.
3.2. DC ZERO ADJUSTMENT
Ensure that the jaws of the clamp are correctly closed and that they do not enclose any conductor. Connect
the clamp to your measurement instrument. Press the auto zero button ➃. The red light ➄ comes on
for approximately three seconds to indicate that the instrument is on zero calibration. If zero can not be
obtained, this indicator light remains lit to indicate the fault.

3.3. MEASUREMENT
After having switched on the clamp, connected it to the measurement instrument on the appropriate
range, and followed the auto zero procedure (see the two paragraphs above), clamp the conductor to
be measured ➀ between the jaws of the clamp.
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
➁ corresponds to the direction of the current owing in the conductor (source ⇒ receiver).
3.4. OVERLOAD INDICATION
Detection of overload of the range of the clamp is indicated by the red light ➄. This indicator ashes for
a peak current greater than 60 A on the 40 A range (10 mV/A) or 600 A on the 400 A range (1 mV/A).
3.5. AUTO OFF
The PAC 11 has an Auto Off feature which switches off 10 minutes after the clamp has been switched
on, without the controls being used.
When the clamp is switched off by this automatic function, the switch ➆ must rst be set to the OFF
position before being switched on again.
This function can be overridden by the user when switching on. Simply press the auto zero button ➃ at
the same time as setting the switch ➆ from the OFF position to the 1 mV/A or
10 mV/A position. If the green indicator ➅ ashes whilst the zero reset button is being pressed, this
indicates that the auto off function has been inhibited.
