TE-BA-e-1812
— deteriorated measurement accuracy due to drastic changes in the operating envi-
ronment of the measurement instrument;
— following replacement of the measuring probe.
Factory settings include both settings for "Fe" (F) and "NFe" (N) materials. It can be
set for one or both of them.
The procedure is described below:
It is different for "Fe" and "NFe" symbols displayed. After "Fe" is displayed, the facto-
ry setting for "Fe" material is set, and after "NFe" is displayed", the factor setting for
"NFe" material is set.
- Press the "ON/OFF" 3-6 button and hold it until "CAL" is displayed. This process
lasts ca. 5 seconds after you have pressed "ON/OFF".
- After the display shows F:H (or NF:H), raise the measuring probe more than 5 cm.
Next, press "ZERO" again, the device will be switched again to the measurement
mode. The factory settings have been restored.
Please note: This process should always be completed within 6 consecutive se-
conds. Otherwise, it will be terminated by the device automatically and the resetting
will be ineffective.

LN function
enables to change the measurement instrument linearity entered during
adjustment (it is controlled by "ON/OFF" button and lasts ca. 11 seconds after the
button has been pressed).
However, it is recommended not to change the
LN value
, as such a change may re-
sult in displaying different measurement results.
Every change of LN value can significantly reduce the measurement accuracy.
This value should be set solely by specialists.
As a general rule: The higher the LN value is, the lower the readout result for the
same layer thickness is. Small change in LN value results in high change in the
readout result in the upper measurement range (for 500 µm/20 mil).
To adjust LN value:
Press the "ON/OFF" button. This process lasts ca. 11 seconds after this button was
pressed.
To change this value, press "Plus" or "Minus" button, and after "LN" is displayed, re-
lease "ON/OFF" button. The value will be saved. To complete the process, press
"ZERO".
A. The readout result in the lower range can be adjusted by pressing "Plus" or "Mi-
nus" button.
B. LN value should be increased when the readout value in the lower range is correct
(e.g. 51 µm), and in the upper it is too high (e.g. 432 µm).
