Out Of Measurable Range Thicknesses; Choosing Which Magnet Type To Use; Units Of Measurement - 493K K-METRON User Instructions

The on-screen indication will now show that the Mould Index number has been
incremented.

1.13 Out of Measurable Range Thicknesses

During the calibration of a spherical or cube magnet the unit will determine at which
maximum thickness the sensor magnets become out of range and then will display O/R for
'out of range' when appropriate. The O/R limit is reached whenever the effect of the
magnet on the sensor head is too small to provide a useful measurement also seen when no
magnet is present, such as would happen when the magnet becomes de-coupled. For a
limit where the thickness decreases to zero and the measurement is out of range, "LOW"
will be displayed.

1.14 Choosing which Magnet Type to use.

The unit comes with two different types of magnet, a cube and a sphere. The desired range
of measurement will be the major factor which determined whether to use the cube or
spherical magnet. The 10mm x 10mm x 10mm cube magnet is best for thick walled parts.
The 10mm spherical magnet is best for thinner parts when tight radii are to be measured.
The measurement specifications for each of the magnets are shown in the Table below.

1.15 Units of Measurement

The measurement can be made in IMPERIAL or METRIC units. To do this hold down the
DELETE button while the K-METRON is off and continue to hold it while switching the unit
on. While continuing to hold down the DELETE button, after a short delay (with Wait ...
Setup mode being displayed) the K-METRON will enter the "Configuration menu" and
display "M1: Cal Object". Release the DELETE button at this point. Pressing the DELETE
button will scroll through the menu. Pressing the DELETE button twice will display "M3:
Units". To Select or Enter a menu the Orange Trigger button is pulled. Use the DELETE
button to scroll through METRIC/IMPERIAL/EXIT and select the desired Units by pulling the
Orange Trigger Button. The unit will now exit the configuration menu and return to
operational status.
