6
OPERATING PRINCIPLES
OF LE050 MODEL
The electronic system is based on a high
performance microprocessor.
The microprocessor is in charge of every
operation within the instrument, going
from the position transducer (a very sen-
sitive LVTD – Linear Variable Differen-
tial Transformer), to the analogue digital
converter, to the system calculation and
data display. Measures are continuously
averaged and processed, in order to re-
duce to minimum the electronic noise and
high –frequency mechanical vibrations.
Sensitivity is as high as 1 µm/m
(0.2 second of arc).
The internal software manages the whole
acquisition process , the measures ave-
raging and the data display on a
galva-
nometer
for analogic readout.
The two selectors on the right side of the
instrument, allow you to choose between
five measure scales and adjust zero.
The level may be complemented by a Win-
dows application

data processing, archiving and printing,
as well as graphic rendering of the sur-
face or line under test. This makes it pos-
sible to produce a complete and accurate
information of the measured surfaces.
