MODEL B310PDC CONTOUR PROBE May 2016
The B310PDC (Pulsed D.C.) Contour Probe is a very portable, battery operated Magnetic
Inspection Yoke designed for Magnetic Particle inspection. It is especially convenient for use
where outside power is unavailable or where operator safety is a concern.
INSTRUMENT DESCRIPTION: The B310PDC Contour Probe is an electromagnet that produces a
strong Pulsed D.C. magnetic field. A circuit board contained within the Probe assembly produces a
high frequency Pulsed D.C. field. All Parker Contour Probes are designed with flexible legs that
allow the field to be "focused" at a precise area of inspection. The maximum leg spacing is 9
inches (228.6 mm). The 310PDC series Contour Probe comes equipped with a 6’ (1.82 m) power
cord.
Although this Pulsed field produces more defined defect indications over that of a pure D.C. field,
the Pulsed D.C. field may not in all instances produce the same sensitivity to detect minute defect
indications that might otherwise be obtained by an A.C. field. Further, the Pulsed D.C. field does
not capture the magnetic field width of the surface test area that is obtained with A.C. Care should
be taken to test for defects in a line between the poles (legs) upon the work surface.
BATTERY PACK: The B310PDC operates from a 12VDC battery.
Parker Battery Packs: P/N: BP-7 (7.2 Amp Hour) and P/N: BP-15 (14.4 Amp Hour).
CAUTION: To dispose of old batteries, follow the regulations of local ordinances
NOTICE: Always refer to applicable standards requirements for intended use and
application. Tests shall be performed to determine acceptable system performance.

GENERAL SAFETY RULES
Please read all instructions. Failure to follow all instructions listed below may result in injury. If the
equipment is used in a manner other than as specified in these operating instructions, the
protection provided by the equipment may be impaired. Always wear eye protection
Do not abuse the power cords. Never carry the instrument by the cord or attempt to unplug the
instrument using the cord. Always operate the instrument with the standard installed cord.
Changing or using a damaged cord can increase the risk of electrical shock. The cord should be
checked periodically for any damage.
Do not position the instrument such that it would be difficult to operate the disconnect device (plug)
on the end of the power cord.
The outside housing should remain intact and solid. Any damage, chipping, or separating exposing
internal wires is a hazard. Instruments should not be used in this condition. The outside housing
should be periodically checked for damage.
Duty Cycle: The 310PDC series are designed for a 50% duty cycle, or approximately two minutes
on and two minutes off. Continuous operation may cause overheating and damage the Contour
Probe.
Operating Environment: Temperature: 32° to 104°F (0° to 40°C). Relative humidity: 10% to 95%, non-
condensing.
Shipping and Storage Environment: Temperature: 40° to 140°F (4.44° to 60°C). Relative humidity:
5% to 95%. Vibration and shock: As encountered in normal shipping and handling with no degradation
General Cleaning
The outside surface of the instrument can be periodically wiped with a clean cloth and a mild
general purpose cleaner. Avoid using cleaners such as lacquer thinner, or mineral spirits that could
damage the outside housing.
Never attempt field service. All B310PDC contour probes should be returned to the factory for
repairs.
OPERATION: Connect the instrument plug into the power outlet of the proper battery.
Place the Contour Probe legs upon the work surface with the suspected defect at right angles to the
legs (Good contact will produce the best results). Push the test switch to energize the instrument.
Lightly dust or float dry magnetic inspection powder over the area being inspected between the poles
(legs). Turn the Probe 90 degrees from the first test and repeat the process. This method may also be
utilized when applying a wet medium. Check all procedures and standards for further details involving
inspection specifics.
ELECTRICAL: The B310PDC obtains its power from a portable 12V battery. A green “Battery
Level” LED is located at the rear of the unit. Should the battery voltage drop to an insufficient level,
the light will go out indicating that charging is necessary. Additionally, if the green LED fails to light
with a sufficiently charged battery, it is an indication that there is a malfunction with the internal
circuit or with the connection to the battery. If a malfunction is suspected, the instrument should be
returned to the factory for repair. The 7.2 amp hour battery should remain at sufficient charge for
approximately eight hours or longer depending on use. The 14.4 amp hour battery should last
nearly sixteen hours or more.

CAUTION: Small parts may become magnetically saturated due to excessive field application. This
may cause a masking effect to the point where it is impossible to define a defect.
WARRANTY: The Parker B310PDC Contour Probe is warranted against malfunction due to defective
material and or workmanship. The defective unit will be repaired or replaced (less incoming freight
charges) for a period of one year from the date of sale. This repair warranty does not apply to altered
units.
The BATTERY PACK is warranted against defects in materials and workmanship for a period of
three months from the date of purchase. CAUTION: Old Batteries should be disposed of in
accordance with local ordinances.
Repair or replacement of the defective unit will be made at the discretion of Parker Research
Corporation. Repaired or replacement unit(s) will be returned to the original customer prepaid.
The obligation of Parker Research Corporation is limited to the repair or replacement of the defective
unit. No other obligation is expressed or implied. Parker Research Corporation assumes no liability
from any claim arising from the use of this equipment.
CAUTION: For the correct and safe use of this equipment, training of operating personnel is required.
Use of proper inspection procedures, standards compliance and safety requirements is the obligation
of the user.
ALWAYS WEAR SAFETY GLASSES WHEN USING THIS EQUIPMENT
