The Color Assessment Cabinet that can be used for color evaluation under specified

lighting conditions.

  • Balanced light that conforms to or exceeds published international standards for the visual evaluation of color
  • An elapsed time meter
  • “Instant-on” capability to eliminate warm-up delays
  • A membrane keypad for rapid switching between illuminants with fingertip control
I.               Applications

Color Assessment Cabinet, suitable for all industries which has high requirement on color consistency and quality- e.g. Automotive, Ceramics, Cosmetics, Foodstuffs, Footwear, Furniture, knitwear, Leather, Ophthalmic, Dyeing, Packaging, Printing, Inks and Textile.

In different light and weather condition, there’s different radiant energy, when they irradiate on an article, it might appear color differences compare with the original. Regarding to color management in industrial production, when a checker has compared the color consistence between mass production and samples, it would be very helpful to do the testing on the color assessment cabinet; it would supply the tester a stable light condition then reduce the error. It’s also very important to use standard light source to check color difference in night duty.

Besides D65 light source, the TL84, CWF, UV, and F/A light sources are available in this Lamp Cabinet for metamerism effect.



Color Assessment Cabinet Assembly


Figure – Color Assessment Cabinet Assembly

  1. Place the Bottom Panel (#D) on a clean, smooth surface.
  2. Fix the Panels (#B,#C & #D) as the above Figure shows, place the Neutral Grey sides

to inside.

  1. Caution! In the following step, DO NOT RELEASE THE HOST MACHINE until you are certain that all Tube Caps are properly seated in their sockets. Move your fingers out of the way before you release the Assembly.
  2. Lift the Host machine up and place it over the four Tube Caps. Rest it on the two rear Tube Caps and gradually seat the Host machine onto the two front Tube Caps in a hinge-like motion. When you are certain that the Host Machine is secure, release it. This completes the Assembly. Proceed to the OPERATION section of this manual.


  1. Applying Power to the Cabinet

Make certain that all lamps are properly seated, and that the unit is placed on a stable, vibration-free surface. Plug the power cord into the female cord receptacle, and then plug the cord into a properly rated wall socket. The display screen will indicate power is on. (Electric supply must comply with nominal electricity of the cabinet.)

  1. Selecting a Light Source, Press the button label:

* D65 for the daylight source;

* TL84 for European & Japan shop light source;

* CWF for the cool white fluorescent source;

* U30 for the commercial fluorescent source;

* UV for the ultraviolet source.

* A /F for the incandescent source;

Note: The ultraviolet source (UV) can be used in combination with any of the light sources or by itself for evaluation of optical brighteners, whitening agents, or fluorescent dyes or pigments.

  1. Testing

Put articles at the center of the bottom in cabinet. The ideal observe angle is 90 degree line of light source, 45 degree line of sight (see Figure.1). Could adjust the angle to fit for different testing article. Comparing the color of two or more articles put them parallel to be tested.

  1. Changing Lamps & Fuse Check

CAUTION: Unplug the power cord from the power source before you replace the lamps and fuse.

  1. Check the elapsed time meter of the control pad to make certain that 2000 or more hours have elapsed since lamps were installed. We recommend that all lamps be changed after 2000 hours of unit operation.
  2. Refer to Figure 2 below to follow the replacement configuration. Replace all lamps.

Note: The F or A bulbs, Tungsten Halogen lamp should not be touched with bare fingers because the oil from the skin will reduce lamp life.

  1. After replacing the lamps, clear the past running time of old lamp (calculate time from zero) as follows: light up new lamps, insert small screw driver into the central hole of CLR and then press it (the timing of lamps did not lit up will not zeroed). Note: To avoiding error zeroing, don’t press CLR key only after replacing lamp.
  2. Open the socket cover back of the cabinet, then exchange the fuse.
  1. Electrical Parameters

Power supply: AC 220V 50/60Hz □

AC 110V 50/60Hz □

Power: Less than 300W

  1. Color Assessment Cabinet Maintenance
  2. Warranty period of Color Assessment cabinet is one year (man-made damage or lamp aging is not in this scope).
  3. The running time and times of turn on/off will affected the life of lamps. If there is a need on turn on/off the lamps in short a time, we suggested keeping it on. In theory, the lamps startup one time equal to running one hour of the lamps.
  4. The lamps used in the cabinet are differing from the ordinary lamps for daily life, when the lamps have to be changed, please buy the lamps from professional franchiser.
