1. PRESENTATION
1.1. STANDARD MODELS IN A A100 SERIES
A100 Series AmpFlex® sensors make up a range of nine standard models which enable the measurement
of alternating current from 0.5 A to 10 kA at industrial frequencies. Each probe is of a exible air-core
type (45 cm, 80 cm or 120 cm) attached by a shielded cable to a small box housing the integrator circuit
and a standard 9 V battery.
Their exibility means that they can be attached to any type of conductor for measurement (including
cables, busbars and stranded conductors), regardless of its accessibility. Because of the latch-type design
of the air-core’s open/close mechanism, it is appropriate to use gloves when operating it.
The box is tted with a two-position switch (single range) or a three-position switch (dual range) and two
LED diodes. One indicates that the device is in use (green LED), and the other warns when the integrator
circuit is overloaded (red LED).
Probes can be connected to any multimeter, tester, recorder, etc. tted with an alternating voltage input
with an impedance over 1 MW (AC mode without a DC component). They have reinforced insulation and
comply with international standards, particularly IEC 61010-1.

3. USE
Do not attach the probe to bare conductors carrying a dangerously high voltage unless wearing
protective clothing suitable for high-voltage work and using appropriate equipment for personal
protection.
The probe is not for use on cables or conductors with a potential of over 1000 V relative to earth.
Illumination of the red LED indicates an overload of the integrator circuit.
If the green LED fails to light, or flashes, the battery requires replacement. It begins
to ash when around 8 hours of battery life remain.
Open the exible air-core, and attach it to the conductor to be measured.
Close the air-core using the latching system.
Centring the conductor and making the air-core as circular as possible will ensure optimum
measurement accuracy.
Connect the box to a multimeter with V AC or mV AC ranges and with an impedance of over 1 MW.
Set the switch on the box to the desired range.
Read off the measurement by applying the ratio indicated by the switch position on the box
(see Chapter 4.4).

repair work carried out by parties other than its own after-sales service team or agreed
repair personnel.
5.1. BATTERY REPLACEMENT
The battery must be replaced when the green LED ashes or fails to light up when the box is used.
Remove the exible probe from the circuit to be measured.
Set the box switch to ‚OFF‘
Disconnect the box from the measurement device.
Unscrew the two fastening screws on the box.
Replace the used battery with a 9V alkaline battery (type 6LF22)
Close the box again, retting the two screws.
5.2. CLEANING
The air-core and its latching system require no special care. Simply ensure that no foreign body is
allowed to obstruct the latching mechanism.
Clean the box with a cloth slightly dampened in soapy water. Clean off with a damp cloth.
Dry immediately afterwards with a cloth or with blown air at 80°C maximum.
5.3. CALIBRATION CHECKING
Like all measuring or testing devices, the instrument must be checked regularly.
This instrument should be checked at least once a year. For checking and calibration, contact one of our
accredited metrology laboratories (information and contact details available on request), at our Chauvin
Arnoux subsidiary or the branch in your country.
5.4. REPAIR
