Application
This is used to locate faulty linearity of the video amplifier or greyscale
setting. Nonlinearities mainly result in a compression of the white level.

Application
The Vertical pattern serves for a quick check of a color monitor’s horizontal
bandwidth and phase behavior of a video transmission. It also, verify video
amplifier and color temperature.

Application
PLUGE is used to perform accurate and consistent line-up of picture
monitors. The usual procedure is to adjust the brightness control of a
monitor so that bar 1 is invisible on the background while bar 2 can be still
distinguished. The white level luminance is mainly
adjusted by the contrast control to 70 ±10 cd/m2 by means of the upper
100% white area of the vertical grayscale.
