Quantum Data 801GC, 801GF, 801GX manual QuartBox

QuartBox

Description	The primary version has a single white box in the
	center of active video. The size of the box is one-
	half the width and height of the active video area
	(a quarter of the entire active video area). The
	secondary version draws a black box on a white
	background.

Test	Brightness control adjustment
Purpose	The wrong brightness setting on your monitor may
	cause other tests such as Contrast, Focus and Beam
	Size to be invalid. An accurate brightness setting
	helps give repeatable measurements throughout
	other tests. This version of the brightness box
	should be used if the display’s specifications call
	for the brightness to be set with one-fourth of the
	screen lit.
Method	Place your light meter probe within the center box
	and adjust the monitor’s brightness control to
	obtain the required light meter reading.
