Carrying out a measurement
Measurement on hot surfaces or light sources is not admissible.
Never stare directly into a bright light source. This could cause damage to your eyes
Measuring non-self illuminating objects
Non-self illuminating objects are textiles, paper, colour prints, leather, etc. These materials must be illuminated
with a defined light source. This light source is located in the sensor head at an angle of 45° to the measuring
surface.

surface.
Proceed as follows for RGB measurement:
• Connect the sensor to the measuring device and turn the device on via the „POWER“ button.
• The measuring device signals this with a beep. Wait until the „Mesu“ icon
• Connect the sensor to the measuring device and turn the device on via the „POWER“ button.

• Place the sensor head (15) flat onto the object to be measured. The
sensor may not be moved or lifted during measuring.
• Briefly press the measuring button (4 or 16) once. Measuring takes
place automatically, which is signalled with a beep. The display indi-

The human eye can differentiate between more colour shades than can be displayed in the
RGB colour space. The HSL colour space therefore corresponds better to the perception of
the eye.
„Hue“ differs the colours from each other and you can tell the colour by its value.
„Saturation“ shows how much colour is applied and how high the colour intensity is.
„Luminance“ (brightness/contrast) shows how radiant or intense the colour is.
