Distance sensor operation test
The distance sensor does not require any calibrating or adjusting. It is only possible to check whether the reading is correct.
To test DISTANCE SENSOR operation, proceed as follows:
Ph.
1
Press on icon.
2 Take out the distance sensor and
move it forwards and backwards
to test whether the magnetic
band takes correct readings. The
values displayed on the left screen
are expressed in millimeters and
must match the graduated scale.
The distance is always measured
in millimeters. Make sure that the
diameter distance board sensors
are not touching the surface of
the graduated scale, to avoid any
mechanical stress.
When the distance sensor is close
to the resting position
(approximately 3 mm distance),
the buzzer sounds, reporting that
the circular magnet has taken the
zero reading correctly.
