Instruction Manual

TC-BA-e-1310 3
8.2.1 The Power- on/ Power- off key 3-6 has to be pressed
until `CAL` appears on the display. This lasts about
5 seconds.
8.2.2 If now F:H or NF:H is shown on the display, the
sensor has to be lifted for more than 5 cm. Then the
Zero- key 3-3 is to be pressed and the instrument
returns into measuring mode. With this, factory
setting is restored.
Comment: This procedure should always be done
within 6 seconds. Otherwise it will be automatically
cancelled and the restoration is invalid.
9. Notes
9.1 The linearization of the instrument, which is given by
the calibration, can be changed with the Ln- function.
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 (coating) 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 is to adjust as follows:
The Power on/ Power off key has to be pressed.
It lasts about 11seconds from starting depressing this
key.
This value can be changed by pressing the Plus- /
Minus- key after `Ln` appears on the display and the
Power- on / Power- off key is released. This value is
stored and afterwards the Zero- key is to be pressed.
A. The reading at low end is to be adjusted by pressing the
Plus-/ or the Minus- key.
B. The value of Ln is enlarged if reading at low end (e.g.
51µm) is o.k., but reading at high end (e.g.432µm) is too
large. In contrast with this the value of Ln is to be de-
creased if the reading at low end (e.g. 51µm) is o.k. but at
high end (e.g. 432µm) it is too small.
C. Procedures from A to B are to be repeated until the
reading for every calibration foil is satisfactory in its
accuracy.
