• Technical Data Intended Use The colour analysis device RGB-2000 is a digital measuring device for optical colour determination and objec- tive quality control. The measuring device is equipped with an external measuring sensor with 45°/0° colour measuring geometry and integrated LED illumination unit. The colour measuring device serves mainly to mea- sure nonluminous materials like textiles, paper, leather, colour prints, etc. The integrated illumination unit can be switched off and also used for comparison measuring of self-illuminating surfaces like CRT picture tubes, LCD monitors or cold illuminants (e.g. LEDs). The colour space can be displayed in RGB values from 0 - 1023 or HSL values from 0 - 1000. Via the relative function, it is possible to perform a fast comparison measurement of references and samples. An RS-232 interface allows the further processing of the measuring data with an optional data cable. A 9 V block battery (type 1604A) is required for operation. Operation with a power pack unit is also possible. Measurements must not be carried out under unfavourable ambient conditions.

You can switch the device back on with the „Power“ button (3).19 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 illuminatedwith a defined light source. This light source is located in the sensor head at an angle of 45° to the measuringsurface.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“ icongoes off on the display. After activation, the measuring device is always inRGB mode.• Press the measuring button (4 or 16) and check the activated sensor illumi-nation. If this is not lit, turn the illumination in the sensor head on via the but-ton „LIGHT ON/OFF“ (9).• Place the sensor head (15) flat onto the object to be measured. Thesensor may not be moved or lifted during measuring.• Briefly press the measuring button (4 or 16) once. Measuring takesplace automatically, which is signalled with a beep. The display indi-cates „Mesu“.• After measuring, turn the device off via the „POWER“ button.The measuring button (4 or 16) must only be pressed briefly. Measuring takes place automa-tically until the measuring values were determined. The current measurement is indicated onthe display with the „Mesu“ icon.Proceed as follows for HSL measurement:• Connect the measuring device as described in the section „RGB measuring“ and turn it on.• To switch to HSL mode, press the button „RGB/HSL“. The display switches tothis mode. Another press returns the device to RGB mode.• Briefly press the measuring button (4 or 16) once. Measuring takes placeautomatically, which is signalled with a beep. The display indicates „Mesu“.• After measuring, turn the device off via the „POWER“ button.The human eye can differentiate between more colour shades than can be displayed in theRGB colour space. The HSL colour space therefore corresponds better to the perception ofthe 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.

Measuring self-illuminating objects Self-illuminating objects are illuminated by a separate, „cold“ light source. These objects are e.g. CRT tubes, LCD/TFT monitors, LED illumination, etc. Hot light sources like common light bulbs and halogen spotlights may not be measured. The measuring device is mainly intended for non-self illuminating objects. Due to the different light sources, the measuring values are not specified in this mode. With self- illuminating objects, the measuring device can only be applied for comparative measu- rement. Proceed as follows for the 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 goes off on the display. After activation, the measuring device is always in RGB mode with activated sensor illumination.

• Switch the illumination function off by pressing the button „LIGHT ON/OFF“ once. A beep confirms your selection.

• Press the measuring button (4 or 16) and check the inactivated sensor illumination. If this is lit, turn the illu- mination in the sensor head off via the button „LIGHT ON/OFF“ (9).

• Place the sensor head (15) flat onto the object to be measured. The sensor may not be moved or lifted dur- ing measuring.

• Briefly press the measuring button (4 or 16) once. Measuring takes place automatically, which is signalled with a beep. The display indicates „Mesu“.

• To switch to HSL mode, press the button „RGB/HSL“. The display switches to this mode. Another press returns the device to RGB mode.

• After measuring, turn the device off via the „POWER“ button. REL comparative measurement Via the REL function, you can perform a simple comparative measuring operation from a reference surface to a sample surface. Deviating values can be easily detected as „+/0/-“ value. Please proceed as follows to activate this function:

• Perform normal colour measurement on the reference object as described for RGB or HSL measuring.

• Once the measuring value is displayed, press the button „REL“ (8). The displayed values are saved as refer- ence. The display blinks and shows „0 0 0“.

• Place the sensor head on the sample surface and press the measuring button once. The comparison mea- surement is in progress and shows the difference value after a brief measuring period.

Performing the RGB calibration. To ensure the accuracy of each measuring operation, the measuring device should be regularly calibrat- ed using the enclosed calibration card. Calibration is only possible in RGB mode and only with non-illuminating surfaces. The sensor illumination must be activated. Proceed as follows for calibration:

• Connect the sensor to the measuring device and turn it on.

• Press the measuring button (4 or 16) and check the activated sensor illumination. If this is not lit, turn the illumination in the sensor head on via the button „LIGHT ON/OFF“ (9).

• Open the envelope with the white calibration card and place the sensor head (15) in the center of the white calibration circle. The sensor head must be plane.

• Press the two buttons „Function“ (7) and „CAL“ (2) simultaneously. The calibration procedure starts and the display shows the following: The start screen appears on the display for approx. 30 seconds. The sen- sor may not be moved or lifted during the entire calibration procedure. After this time, the first calibration value appears on the display. The second calibration value appears after approx. 10 seconds. Finally, the third calibration value is displayed after another 10 seconds. The end of the calibration procedure is signalled by three beeps. The CAL symbol disappears after this procedure. Now the measuring device is ready for further measuring operations.
