5 CALIBRATING THE K-METRON
After the K-METRON is calibrated with each type of magnet the values are stored within the
K-METRON memory. There re-calibration is not necessary when switching between
magnets; instead the desired magnet is chosen in the configuration menu.
The K-METRON's accuracy improves with careful magnetic coupling between the sensor
head and the part face. Measurement accuracy ranges from +/- 0.2mm at the lower end of
the readings and +/- 1mm at the upper end of measurement. This will depend on whether
the spherical magnet or the cube is used.
Although the units are calibrated before leaving 493K re-calibration may be necessary
within your plant.
Select a location that is at least 1 metre away from any steel or ironwork which will affect
accuracy of calibration.
Re-calibration is not required for use with differing materials.
5.1 Entering Calibration Mode.
With the unit turned OFF hold down the DELETE button. While still holding the DELETE
button down (in one hand) turn the unit on (with the other hand). Therefore on switch on,
when the display lights up, release the ON/OFF button but continue to hold down the
DELETE button for a few seconds when "M1: Cal Object is displayed then immediately
release the DELETE button while waiting the display will read "Wait ... Setup mode". This is
an instantaneous press holding for an extended period will result in the unit turning off!
The K-METRON is now in the configuration menu. Scroll through the menu using the
DELETE button and select "M2: Calibrate" by pulling the orange trigger. The unit will
prompt for re-confirmation and this is acknowledged with the orange trigger.
5.2 Calibrating the K-METRON.
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. The magnet should be placed on the 20mm 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
down. 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.
