! ! WARNING !!
(Do not use until you have read this!)
High-voltage potentials may exist in the vicinity of the desired current measurements.
Use locally approved safety procedures when working near high-voltage potentials. It
is recommended not to install the Flexible Transducer around a live bus that is at a
high-voltage potential. If installation is not possible when the bus is disconnected from
main supply, use appropriate gloves and/or equipment that are approved for working
around high-voltage potentials when installing the Flexible Transducer in the vicinity of
these hazardous potentials.
INTRODUCTION
The AMPROBE Flexible AC Current Transducer Model ACF-3000 SR is an assembly
similar in purpose to a CT or current transformer. It may be used to measure AC
currents from a low as a few amps to a maximum of 3.0kA rms. The device output is
an analog voltage that is proportional to the current in the conductor. The output signal
is isolated from the hazardous conductor potential and is an exact replica of the AC
current wave form in the conductor. The output signal is available via a 2 pin snap
connector.
ACF-3000 SR ELECTRONICS PACKAGE
The ACF-3000SR electronics package is permanently connected to the transducer.
When the ACF-3000 SR is turned on, the LED mounted behind the front label blinks
once, then goes out to minimize drain on the battery. When the batteries are nearing
the end of their life the LED flashes approximately twice per second, the batteries
should be replaced and as soon as possible. If the LED fails to flash once when the
unit is turned on, the batteries are dead, replace immediately.
The ACF-3000 SR comes equipped with an external mini jack located on the package.
This is for those wanting to supply power to the ACF-3000 SR for a longer period than
the internal battery life will allow. An external DC power supply is available for this
purpose but is sold as an option. The power required is +3.0VDC/10mA.

The ACF-3000 SR design utilizes the light weight and flexibility of the Flexible AC
Current Transducer. This transducer is a versatile current probe that may be wrapped
around most conductors. Its application versatility and high voltage isolation rating
clearly distinguish the ACF-3000 SR from other current measuring methods. The
measuring transducer is constructed from nonferrous materials, minimizing any circuit
loading.
Note: The ACF-3000 SR will produce twice the output if you wrap the
transducer round the conductor twice.
The frequency response of the ACF-3000 SR is wide compared to conventional CTs.
This allows the user to monitor a much wider range of line harmonic components than
conventional CTs allow. The ACF-3000 SR was designed to be very flexible, larger in
aperture and smaller in cross section than many conventional CTs. This allows
measurement in tight places as never before possible.

The ACF-3000 SR was designed to allow the operator to connect this measurement
device around a conductor without disconnecting the conductor as many CTs presently
demand. The Flexible AC Current Transducer is installed around the conductor with the
moulded-in-arrow on the latch (Fig.4) pointing in the direction of conventional current
flow. Conventional current flow is defined as current flowing from the positive to the
negative potential, or in case of AC current the arrow should face the load.
The Flexible AC Current Transducer must be installed with the interconnection cable
on the outside of the loop when the latch is engaged. The polarity arrow, the double
insulation, and the warning symbols will all be on the outside of the loop.
There is minimal shock hazard using the ACF-3000 SR, as the transducer does not
generate high voltages at low frequencies. Each transducer has been Hi-Pot tested to
several thousand volts with no voltage breakdown. This particular characteristic allows
high-current measurement (with a wide frequency bandwidth) of conductors at less
than 600VAC potential to earth. Do not exceed the minimum bending radius of the
Flexible AC Current Transducer when installing the transducer around the conductor.
Exceeding the bending radius will degrade the measurement accuracy.
Make sure the Flexible AC Current Transducer and its output cable are clean before
installing them around the conductor. If the transducer and cable are not clean the
contaminants on them may provide a conductive path for a high-voltage breakdown.
Also, check the transducer and output cable for cuts and abrasions. Do not use the
transducer if damaged.
To measure AC current, open the ACF-3000 SR by squeezing the latch, encircle the
conductor to be measured, then snap the ACF-3000 SR ends together (Fig.4). Connect
the ACF-3000 SR output cable to your measuring instrument using an adaptor.

Maintenance
Preventative maintenance primarily consists of cleaning the transducers and cables to
prevent surface contamination. Use a mild detergent and water to clean the
transducers and cables. Remove the detergent with clear water, then wipe dry with a
clean cloth.
Note: The use of solvents as cleaners is not recommended unless thoroughly
tested and found harmless to all surfaces and parts. Do not submerse
current transducer into water or other fluids.
