Loss Of Magnetic Coupling; Tracking The Sensor Head To The Point Of Measurement; Ensure Correct Sensor Head Orientation - 493K K-METRON User Instructions

Hollow objects can be measured by inserting the calibrated magnet through a small opening
in the product. The magnet should immediately be coupled with the sensor head positioned
on the outside of the product and adjacent to the aperture. The sensor head can then be
slid over the surface of the product to the desired place of measurement. Movement should
be slow and steady. Care should be taken when moving the sensor head to avoid de-
coupling.

1.4 Loss of Magnetic Coupling.

When magnetic couple of the cube magnet is lost it can be retrieved by retaining the end of
the attached cord and fishing the magnet out of the opening. If the spherical magnet loses
coupling then it must be retrieved by turning the moulding upside down and allowing the
magnet to fall out or by using a telescopic metal pointer to grab it.

1.5 Tracking the Sensor Head to the Point of Measurement.

The calibrated magnet will automatically couple, orientate and centre itself over the Sensor
Head. Once coupled track the Sensor Head to the point on the part which you wish to
measure, taking care not to remove the sensor head from the face of the work piece. This
may result in the loss of the magnetic coupling. The calibrated magnet will follow the Sensor
Head to the desired point of measurement.

1.6 Ensure Correct Sensor Head Orientation

When measuring flat parts ensure that the sensor head is perpendicular to the surface.
When measuring external radii it is important to ensure that the sensor head is
perpendicular to the surface of the part being measured.
Incorrect Sensor Head Orientation: a non-perpendicular orientation will result in an
erroneous measurement.
