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
defective pixels at the surface of the screen.
The SEFRAM quality service has preconditioned the mounting of the screen on your instrument to the
respect of the acceptance conditions of the manufacturers.
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
respect 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
expected.
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.
