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 OPERATE
unit from a DC power source.
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 310 series are designed for a 50% duty cycle. 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 310 series contour
probes should be returned to the factory for repairs.
OPERATION:
Connect the instrument plug into a
Grounded power outlet of proper voltage. 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. Defect indications will be revealed
in a direction shown on figure 2. Turn the Probe 90
degrees from the first test and repeat the process.
This method may also be utilized when applying a
