K-METRON Radio User Instructions (Firmware 2.3.4; Doc v3.0.0)
The more accurately you can teach the K-METRON the thickness that it is measuring during
calibration, the greater the accuracy of the part thickness measurement in the field.
Continue this step by step calibration down to the 'Zero' thickness with the magnet directly
on the sensor surface.
If you make a mistake during the calibration sequence, press the DELETE button to go back
to the previous position.
THE CUBE AND SPHERICAL MAGNETS ARE NOT INTERCHANGEABLE AND DOING SO WILL
RESULT IN INACCURATE READINGS. THE MAGNET TYPE MUST BE SET IN THE
CONFIGURATION MENU BEFORE USING THE K-METRON. IT IS ADVISABLE TO STORE ANY
UNUSED MAGNETS IN THE K-METRON CASE TO AVOID MISTAKENLY LOSING OR USING
THE WRONG MAGNET.
5.3 Validating Calibration.
After calibration is complete the measured data should be validated. To do this position the
calibrated magnet once more on each step and ensure the K-METRON'S measured and
displayed value is that of the actual step thickness (note the measurement tolerances as per
the table above apply).
6 THE SENSOR HEAD
DO NOT ALLOW THE TRANSDUCER MAGNET TO 'SNAP' TO THE FACE OF THE SENSOR –
SEVERE DAMAGE MAY OCCUR TO THE DEVICE SENSOR AND MAGNET.
Keep the Sensor Head and magnet away from computer displays or any product which is
sensitive to strong magnetic fields. Permanent damage may occur to such devices.
The Sensor is highly sensitive to magnetic fields and temperature. High temperature
environments may also affect the accuracy of readings.
The instrument has been factory calibrated to accuracies shown in the table above.
Regular checks should be made to ensure the instrument is operating within its capabilities
and it is recommended that the unit is returned to 493K Limited for an annual recalibration
to ensure its continued performance is maintained. 493K offer a return carriage paid
service, calibration and inspection.
7 MEASURING DIFFERENT MATERIALS
No calibration is required for use with differing materials. This equipment will measure
materials of a thickness between 2mm to 20mm where access can be achieved to both sides
of the product being measured.
