11. Notes

With the LN function, the linearization of the measuring instrument specified by the
calibration can be changed. However, it is strongly recommended not to make any
changes to the LN value, as this change will lead to deviating measurement results.
Any change in the Ln value can significantly affect the measuring accuracy. This
value should only be set by qualified personnel.
In general, the larger the Ln value, the smaller the reading result for the same layer
thickness. A small change of the Ln- value causes a large change in the reading
result in the upper measuring range (at 500µm/ 20mil).
Thus the Ln value is to be corrected:
Pressing the on/off button: It takes about 11 seconds from the beginning of pressing
the on/off button.
Its value can be changed by pressing the Plus or Minus key after 'LN' appears in the
display and releasing the On/Off key. The value is stored and then the zero key is
pressed.
A: The reading result in the lower area is corrected by pressing the Plus or Minus key.
B: The Ln value is increased if the reading result is correct in the lower range (e.g.
51µm) but too large in the upper range (e.g. 432µm).
In contrast, the Ln value is reduced if the reading result is correct in the lower range
(e.g. 51µm) but too small in the upper range (e.g. 432µm).
C: This procedure of A. and B. is repeated until the reading result is satisfactory in its
accuracy for each distance foil.
