Calibrating The K-Metron - 493K K-METRON User Instructions

K-METRON Radio User Instructions (Firmware 3.0.4; Doc v4.0)

4.2 Calibrating the K-METRON.

Once in the Calibrate Menu the display should now read NM – no magnet. With no magnet
near the sensor head, the trigger should be depressed and released.
After successfully acknowledging 'NM – no magnet' the unit will then request the 20mm
position (+10mm disk for 10-30mm magnet). The magnet should be placed on the
20mm(+10mm disk for 10-30mm magnet) step and the trigger pulled. Confirmation of step
calibration will be provided and then the next step thickness requested, i.e. 19mm. Slide the
magnet onto the next step ensuring that it does not snap onto the next step to avoid
damaging both the magnet and calibration step tool. The next position will be requested,
i.e.18mm, and so on.
The magnet should be placed on each step so that it is in the centre of the step and is not
interfering with the step edge. The sensor head should be centred on the magnet. Ensure
that the magnet is not moving when calibrating as this will affect the calibration values.
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 X (or "Delete") button to
go back to the previous position.
For use of 19mm Spherical Magnet to use for the 10mm-30mm measurement range:
Please note that a 10mm aluminium Disk is provided.

+10mm Calibration
Add-on
The disk features a groove for the sensor head to easily slide into, allowing the operator to
calibrate +10mm in conjunction with the provided calibration step profile.
