This DTV Color Rendition Test Chart Instrument are Certified with

1 Years Warranty (Additional support period of 3 years)

The YE0226 is designed for the evaluation of the color rendition of HDTV cameras. The chart consists of 36 color patches and a 9-step gray scale. In addition to the primary and secondary colors the test chart contains mainly the colors, which are critical in reproduction, e.g. dark and light skin tones, foliage, blue sky, orange, violet and others.

The chart consists of 36 color patches and 9-step gray scale. Besides the primary and secondary colors (blue, green, red, yellow, purple and cyan) the test chart contains mainly colors, which are critical in reproduction, e.g. dark and light skin tones, foliage, blue sky, orange, violet and others.

The colorimetric reports of the 36 colors are shown on the following page.

The 9-step gray scale is graduated as follows:

Step	Density	Transmission in %
1	0.00	100

2	0.06	88

3	0.20	63

4	0.36	44

5	0.55	28

6	0.81	16

7	1.15	7

8	1.65	2

9	> 3.00	0

The density is based on the 1st step of the gray scale.

Date

Some of the filter foils used are not fade less, especially when exposed to sunlight (ultra violet light). We therefore recommend to store the chart in the folder or case when not in use. We also recommend and offer a recalibration of the chart after 3 years of regular use.

FAQs About Color Test Charts

D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.

a. If this phenomenon occurred, it means the battery power is not enough. You need to charge the battery.

b. When charge the battery, please insert the battery to the instrument, and plug in the adapter to charge the battery. After 5 minutes, the instrument can be turned on.

c. If the instrument still cannot be turned on after charging 5 minutes, you can pull out the adapter and re-plug in to check it. Or repeat this operation.

d. If the instrument still cannot be turned on after charging 5 minutes, you can turn off the colorimeter and turn on it again to check it. Or repeat this operation.

e. If you have tried all the methods above but the colorimeter still cannot be turned on, please change the battery.

Threenh Technology colorimeters provide a color deviation prompt function according to the Lab value, which can provide a reference for color matching. The handheld colorimeter can only indicate blacker, whiter, redder, greener, yellower or bluer, but it cannot provide accurate color formulas. Only with the help of a spectrophotometer and professional color matching software can fully realized automated color matching.

You can choose a colorimters depending on the substrate you are measuring the color of, whether it is opaque, translucent or transparent. In short, you can consider the following factors for choosing the right 3NH colorimeter for your needs: Sample Opacity, Physical Form, Optical Properties needed, Measurement Methods required, Scales and Indices needed, Instrument Standards Conformance (ASTM/ISO/Other), Instrument Geometry, Instrument Performance, Location (laboratory, portability, in-process) and Sample Handling requirements.

By systematically addressing these factors, you can select a colorimeter that optimizes accuracy, efficiency, and value for your specific application.Learn more from our ultimate guide on colorimeter selection. If unsure, consult the 3NH manufacturer for personalized recommendations based on your sample and workflow.
