A6303 & A6303XL Instructions 1
Getting Started
This section covers the installation and operation of the A6303 & A6303XL
current probes.
The A6303 is a DC to 15 MHz current probe designed for use with the AM503
family of current probe amplifiers and the 11A16 plug-in. The A6303 can
measure currents to 100 A (DC + peak AC), and up to 500 A peak current (while
not exceeding the amp-second rating).
The A6303XL is an extended length cable version of the A6303. It offers the
same current ranges as the A6303 with a diminished frequency range of DC to
10 MHz. The A6303XL can only be used with the AM503B and AM5030, and
will not be recognized by other current probe amplifiers.
Please refer to the amplifier documentation for verification procedures, adjust-
ments, and additional specifications.
If you need assistance using your probe, please call our Customer Support Center
at 1-800-TEK-WIDE (1-800-835-9433). If you are outside the United States or
Canada, please contact your nearest Tektronix Service Center.
Probe Installation
To connect a current probe to the Amplifier input connector, align the tab of the
probe connector with the slot in the Amplifier INPUT connector as shown in
Figure 1(a). Align the dot on the probe connector with the groove opening of the
input connector as shown in Figure 1(b). Push the probe connector in while
twisting the barrel clockwise to lock the connector.
CAUTION. Handle current probes with care. Do not drop a probe or subject it to
impact, or the core may crack. Do not connect or disconnect a current probe
while the probe is clamped around a live conductor or while the Amplifier is
powered on, or the probe may suffer electrical damage.

Operating the Current Probe Slide
Each current probe has a slide that opens and closes the probe jaw. This allows
you to clamp the probe around a conductor under test. The slide must be locked
to accurately measure current or to degauss the probe. If a probe is unlocked, the
PROBE OPEN indicator on the Amplifier will light.
WARNING. When the probe slides are open, the exposed ferrite core pieces are
not insulated.
To avoid injury or equipment damage, remove power from an uninsulated wire
before clamping the current probe around it.
Never disconnect the probe from the Amplifier when the probe is connected to a
live conductor.
Allow your hands to contact the probe handle and lock only.
Figure 2 illustrates the slide operation of the probe. To open the probe, press the
bottom of the lock button and squeeze the handle until the core is open. To lock
the probe, release the squeeze handle and press the top of the lock button.
