Amprobe ACF-3000 SR Mode D'emploi page 7

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.
