AM503 Current Measurement Family
AM503 Family Current Probes - A6312, A6302, A6302XL, A6303, A6303XL,
A604XL, CT4
A total of six current probes are available for
use with the AM503B and AM5030 Current Probe Amplifiers. Since all
six probes are of the split-core mechanical design, they easily clip
on and off of a conductor. All the probes provide simultaneous DC
and AC current measurements with a wide range of current amplitude
and bandwidth capabilities.
The AM503 Current Probes convert
the DC and AC flux field of a conductor to a voltage signal which
is sent to an AM503B or AM5030 Amplifier. The probes include both
a Hall Effect device, which senses the DC current, and a ferrite transformer
which senses the AC current. The probes also utilize a bucking current
from the Amplifier, which eliminates core saturation. The bucking
current is 20 A for the A6302XL, 100 A for the A6303XL, and 500 A
for the A6304XL.
A6312, A6302, and A6303 Current Probes
The A6312, A6302, and A6303 offer a wide range of current measurement
capability for the lab and bench environment. The A6312 covers frequencies
from DC to 100 MHz while the A6302 covers DC to 50 MHz. Both clip
onto conductors up to 3.81 mm (0.15 in.) and measure continuous currents
up to 20 A and peak currents up to 50 A as long as they do not exceed
the amp*second product of 100 A*μs.
The larger A6303 measures
higher amplitude, lower frequency currents. It clips onto conductors
up to 21.1 mm (0.83 in.) in diameter. Its frequency range is DC to
15 MHz. It will measure continuous currents up to 100 A and peak currents
up to 500 A, as long as the amp*second product of 10,000 A*μs is not
exceeded.
The A6302 and A6303 are also compatible with the
11A16 2-CH Current Probe Amplifier for the 11000 and DSA Series oscilloscopes.
With the 11A16, the A6302 is rated for 10.5 A, and the A6303 for 52.5 A.
Note: The A6312, A6302XL, A6303XL, and the A6304XL are
not compatible with the 11A16.
XL Series Current Probes
The three XL current probes add both convenience and expanded
current measurement capability. The XL probes are designed to operate
with the AM503B and AM5030 Current Probe Amplifiers. They are incompatible
with the older AM503 and AM503A amplifiers. The XL (for extra long)
probes have eight-meter cables, which allow you to reach test points
on large devices such as heavy duty motors or automobiles. In addition,
connecting to test points on transportation platforms such as trains,
ships, or aircraft is much easier with the XL probes.
The A6302XL
and A6303XL are modified versions of the A6302 and A6303 probes. The
A6302XL can measure 20 A continuous (50 A peak) signals from DC to
17 MHz. The A6303XL can measure 100 A continuous (500 A peak) signals
from DC to 10 MHz.
The A6304XL is rated for 500 A continuous
(700 A peak) and is the same size as the A6303XL. The A6304XL has
a bandwidth of DC to 2 MHz and is especially well suited for measurements
on high-performance inverters, motor drives, and other high-current
switch-mode control devices. The eight-meter cable makes it very easy
to access test points on devices physically separated from your measurement
instrument.

CT4
CT4 Current Probe
The CT4 is a robust clip-on high-current
transformer that extends the measurement capability of the P6021,
A6302/XL, A6302, A6312, and TCP202 clip-on current probes. Maximum
low-frequency performance down to 0.5 Hz is obtained using the AM
503S. Current amplitudes to 20,000 A may be measured using the A6302/XL,
P6021, A6302, A6312, or TCP202 (with passive termination), provided
the amp*second ratings are not exceeded.
The CT4 may be used
with the P6021 for measurements at normal line frequency and above.
(The P6022 and A6303 are not compatible with the CT4.)
The
CT4 has receptacles for current probes in either 20:1 or 1000:1 step-down
ratios.
The 1.5 in. square split-core opening makes it possible
to clip onto large conductors without breaking the circuit under test.
Insulated core and shield assemblies allow measurements on bare wires
to 3000 VP (1000 VRMS CAT III) and to 14 kV
with the included high-voltage bushing.
