Performing the luminance
measurements

F.7

In this test the veiling luminance (environmental lighting) and
the maximum contrast are tested.

F.7

✧

Switch the monitor off and wait at least 30 seconds.

✧

Adjust then the room lighting to the operating conditions
using the dimmer switch.

✧

Measure veiling luminance Ls at the center of the screen
with the luminance meter.

When taking measurements with the luminance meter, observe
the distance recommended by the manufacturer (40 - 60 cm).

F.7

✧

Switch on the monitor.

✧

Select test image 1 to measure the minimum and maxi-
mum luminance.

In test image 1, the squares for the maximum greyscale value
(L

max.

, bright field) and the minimum grayscale value (L

min.

black field) are used.
