Hanging Color Assessment Viewer QT-CC120-W

Operation Instructions:

1. Insert the power cord and the docking station into the power socket located at the top of the Color Viewer. Ensure the other end is connected to a mains power supply that matches the Color Viewer's indicated input power.
2. To activate a specific light source, press the corresponding light source switch. The respective light source lamp illuminates, and the Color Viewer's timer starts counting. To switch between light sources, turn off the current light source and press the switch for the desired light source. To activate multiple light sources simultaneously, press their respective switches together.
3. Position the item to be inspected at the center of the table. When comparing colors of multiple items, place them side by side on the table and align them as centrally as possible. Avoid placing unrelated items on the tabletop during work to prevent interference with color perception.
4. After completing the test, turn off all activated light source switches. Power off the Color Viewer when not in use, and if it won't be used for an extended period, unplug the power cord.
5. When replacing the lamp tube, locate the two white cap screws on the front of the light-transmissive glass. Unscrew these and gently lower the light-transmissive glass. Remove the lamp that needs replacement and install the new one, ensuring correct positions for different light sources to avoid errors.

Considerations for Daily Use and Maintenance of the Color Viewer:

1. Standard light source usage: Allow the light source lamp to illuminate for 30 minutes to reach optimal color temperature, color rendering index, and illuminance. Avoid frequent switching unless necessary to extend the lamp's lifespan.
2. Light source lamp lifespan: After 2000-3000 hours of use, the standard light source lamp's color temperature, color rendering index, and illuminance will diminish. It's advisable to replace it promptly to maintain the desired color effect.
3. Cleaning and maintenance: Before cleaning or performing maintenance, disconnect the power plug to ensure safety. Use a standard cleaning agent and a clean, soft cloth to wipe the device. Avoid direct washing with water.
