Calibration sources can be obtained from a number of suppliers, in this example will
we use the CALI-T50 from Viso Systems which is a tungsten irradiance lamp. The
spectrum of the calibration source is usually provided in a .lmp file (lamp file).
NOTE!
Making a custom calibration does not delete the Viso factory calibration. You
can always switch between factory and custom calibration at any time.
IMPORTANT:
Calibration must be made in a dark environment, with non-reflective
surfaces.
These steps show how to make a custom calibration.
1 Place the calibration lamp at the center of the rotation motor and make sure it is
lifted to the right height by using the alignment tool.
The lamp must be pointed directly towards the sensor. Sometime is might be
necessary to unplug RJ45 cable to the motor to enabling precise alignment
