Parker DA400 Operating Instructions

The 400 Series Contour Probes are rugged high performance instruments designed for
Magnetic Particle inspection to accepted Nondestructive testing standards.
INSTRUMENT DESCRIPTION: Basically, the Contour Probe is an electromagnet producing a
strong magnetic field. Placement of the two poles (legs) upon ferrous metal provides a path
for the intense magnetic field to pass from one pole to the other. The part completes the flux
path and becomes highly magnetized. Models A410, A410S and A448 produce strong
constant AC fields. Electronic circuitry contained within the molded housing of the DA400 and
DA400S models permits selection of a strong constant AC field, or high intensity half wave
rectified (DC) field. All Parker Contour Probes are designed with flexible legs that allow the
field to be "focused" at a precise area of inspection. Maximum leg spacing is 12 in. (304.8mm).
All 400 series Contour Probes come equipped with a 10' (3.048 m) power cord.
The DA400 and A410 are for use on 115VAC 50-60 Hz, single phase grounded power
source. Using an approved GFCI is recommended.
The DA400S and A410S are for use on 230VAC 50-60 Hz, single phase grounded power
source. The DA400S and A410S are sold without power cord plugs. Only locally approved
plugs should be used and installed by certified personnel. Using an approved GFCI is
recommended.
The A448 is for use on 42-48VAC 50-60 Hz, single phase grounded low voltage power
source. The A448 is sold without a power cord plug. Only locally approved plugs should be
used and installed by certified personnel. Using an approved GFCI is recommended.
