Getting Started
Product Description
This section explains how to install and operate the A6302 and A6302XL current
probes.
The A6302 is a DC to 50 MHz current probe designed for use with the AM 503
family of current probe amplifiers and with the 11A16 plug-in. With the AM 503
family, the A6302 can measure currents to 20 A (DC + peak AC), and up to 50 A
peak current (while not exceeding the amp-second rating). With the 11A16
plug-in, the A6302 can measure currents to 10.5 A.
The A6302XL is an extended length cable version of the A6302. It offers the
same current range as the A6302 with a diminished frequency range of DC to
17 MHz. The A6302XL can only be used with the AM 503B and AM 5030, and
will not be recognized by other current probe amplifiers.
The probe performance specifications, verification, and adjustment are unique to
the amplifier that the probe is plugged into. Please refer to the amplifier
documentation for specifications and verification procedures.
