14.2.3 If now NF:H appears in the display, the sensor has to be lifted for more than
5cm. Then the Zero- key has to be pressed and the instrument returns into meas-
urement mode. With this, factory setting is restored.
Comment: This procedure should always be finished within 6 seconds. Otherwise it
will be automatically cancelled and the restoration is invalid.

15.1 All settings, including restoring factory setting, unit setting, S/C setting should be
finished within 6 seconds. Otherwise this procedure will be cancelled by the instru-
ment, it will quit and keep the status as before.
15.2 The linearization of the instrument, which is given by
the calibration, can be changed with the Ln- function. Linearization is commanded
by the Power-on/ Power-off key and it lasts about 14 seconds from starting to press
this button.
Nevertheless, it is strongly recommended not to perform any alterations of the value
of LN, because those alterations might lead to deviations the measurement results.
Any adjustment of the value of Ln will seriously affect the accuracy. This value
should only be adjusted by professional persons.
Generally said:
The bigger the value of Ln, the smaller the reading on the display for the same (coat-
ing) thickness. Only a small change on the value of Ln causes a big change in the
reading of the upper measurement range (at 500µm/20 mil).
The value of Ln has to be adjusted as follows:
Press the Power-key: It lasts about 14 seconds from starting pressing this key. This
value can be changed by pressing the Plus- respectively the Minus- key after `Ln`
appears on the display and the Power-on/ Power-off key is released. This value is
saved and then the Zero-key has to be pressed.
A. The reading at low end is to be adjusted by pressing (confirming with)
the Plus-/ or the Minus-key.
B. The value of Ln is enlarged if the reading at low end (e.g. 51µm) is o.k., but the
reading at high end (e.g.432µm) is too big.
In contrast with this, the value of Ln is to be decreased, if the reading at low end
(e.g. 51µm) is o.k., but at high end (e.g. 432µm) it is too small.
C. This procedure from A. and B. has to be repeated, until the reading for every
calibration foil is satisfactory in its accuracy.
