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.
Warning:
Do not change the AC/DC selector switch with the probe on.
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 400 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 clean 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 400 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
wet medium. Check all procedures and standards for
further details involving inspection specifics.
