INFORMATION ABOUT THE LCD COLOR SCREEN WITH ACTIVE MATRIX
Your SEFRAM field strength meter is equipped with a LCD color screen with active matrix.
This screen is provided by renowned manufacturers. In the current technical conditions of manufacture, they
cannot guarantee 100% good functioning pixels in the display zone. They specify a number of possible de-
fective pixels at the surface of the screen.
The SEFRAM quality service has preconditioned the mounting of the screen on your instrument to the re-
spect of the acceptance conditions of the manufacturers.
B ZONE
A ZONE
(Diagonal 60% B)
Acceptance criteria:
Zone A (central zone): total less than 5 defective pixels, less than 3 contiguous pixels.
Zone B (total surface of the screen): less than 9 defective pixels on the whole surface of the screen, with re-
spect of the conditions prevailing in zone A.
Is considered as defective any pixel on screen that does not light up or lights up in a different color as ex-
pected.
The contractual guarantee on your field strength measurer can be exerted only if these criteria are not met,
as well at delivery as during the period of guarantee.
