Calibrating The Sensor - Liemke KEILER–25 LRF Manual De Instrucciones

10. CALIBRATING
THE SENSOR
When the image is degraded or uneven, it can be
improved by calibration. Calibration enables the
detector temperature background to be equa-
lized and defects in the image to be eliminated.
There are two calibration modes: manual (M) and
automatic (A). Select the required mode in the
CALIBRATION section of the MAIN MENU.
> M mode (manual)
The device needs to be calibrated manually.
– Short press the Up (4) + Down (3) button
for shutter calibration, and long press for
background calibration.
– The lens cap should be closed for back ground
calibration.
> A mode (automatic)
The device is calibrated autonomously by the
software algorithm. The lens cap need not be se-
cured (the sensor is closed by an internal shutter).
NOTE!
Manual shutter calibration and manual
background calibration
are still possible even in mode A.
