NJ-10-100A is designed for operational adjustment and control of TV cameras. It consists of circles permitting rough visual appraisal of scan linearity, grid lines serving the purpose of adjusting registration and wedges serving the purpose of resolution appraisal.

A grid structure consisting of 23 horizontal and 35 vertical lines is arranged on a white background. 3 grid lines each divide the outer 3 grid rows in the middle. The width of the grid lines is 0.15% of the picture width. The large circular line has a diameter of 83 1/3% of the picture height, the 5 small circular lines have a diameter of 25% of the picture height.

4 resolution wedges are arranged in the large circle at angles of 0°, 45°, 90°, and 135° corresponding to signal frequencies of 2-10 MHz. (The marking ends at 8 MHz and 600 lines).

A colorimeter measures the amount of light and the wavelength that is absorbed by a solution. It is a sign that colored compounds are present and the level of their concentration. It is applied in the laboratory and industry to check the concentrations of chemicals, the color of products, and purity.


Depending on the scale of the manufacturer, its matte, low-sheen finish can be called gloss level 3. Overall, gloss levels in certain standards go between 1 (flat) to 7 (high gloss). Level 3 is considered low-gloss or satin-like.


The measurement of color varies according to context in several units. Such common units are L*a*b* (CIELAB), RGB (Red-Green-Blue), and color difference (Delta E). In light absorption, there are no units assigned to absorbance. But the quantitative analysis of absorbance obeys Beer's Law in colorimetry.
