The setting area (3)
Post calibration
Enables the selection of a calibration standard. Once a standard is
selected, the values of the standard can be retrieved via the
get actual values
button.
To use the „Port calibration” function:
1.
Open the drop-down menu and select a standard.
If you select
no post calibration 1:1
no standard is selected and no
calibration is performed.
2.
Click on the
get actual values
button.

The settings of the selected standard are displayed in the display
window.
Color temperature
Adjusting the colour temperature.
The colour temperature can be entered numerically or changed using the
arrow keys. When a colour temperature is entered, the CIE values x and y
are intuitively adjusted. This point in the CIE coordinates system is
referred to as the whitepoint.
The colour temperature is a measurement for the colour rendering of a
light source and is represented in the unit [K] Kelvin. Various ambient
conditions (daylight, artificial light) display varying colour temperatures.
The cube wall can be adjusted to these ambient conditions.
The table below displays some of the typical colour temperature values:

Manual input of brightness.
The software calculates the brightness and the whitepoint
based on the current settings of the cube wall. An average
value is calculated from the recorded colour and brightness
of all cubes. This option is useful when no explicit
whitepoint or colour temperature is required.
