Start measurement
- Follow the instructions from the previous page:
- Turn the diffuser away from the lens; see illustration.
- Place the elastic strap around the BeoVision 12-65 and the measurement
device as shown in the illustration. The elastic strap must be tightened using
the plastic buckle.
- Make sure that the measurement device is pressed firmly and perpendicularly
to the screen surface, minimising the influence of the ambient light.
- Place the measurement device so that the lens is inside the green area on
the screen and it is kept fixed in a steady position by the elastic strap.
The
START MEASUREMENT
function will first be highlighted when the lens
is in a proper position.
- Press the
Centre
button to start the measurement.
The measurement sequence measures various intensities of white and a
number of colours.
Note:
The measurement sequence takes up to 4 minutes. Do not touch the
measurement device during this period!
When completed the following text is shown in the lower right corner of the
screen:
SCREEN MEASUREMENT PERFORMED SUCCESSFULLY
The sequence returns to the
SCREEN MEASUREMENT
menu with the
MEASURE LIGHT SENSOR
highlighted.
In case the measurement fails an error message will be shown.
In that case, check and reposition the measurement device assuring it is pressed
firmly and perpendicularly to the screen and make sure that the lighting
conditions in the room are as dark as possible. After this the above
measurement must be made again.
