Uniformity Correction Adjustments
- RS232 connection from the PC to the projector and to the color meter. Allow the
projector to warm up during 10 minutes. Put the lamp into the highest power mode.
Close the hoods on the projector. Put the projector in FRONT TABLE configuration.
Darken the room before the evaluation or the measurements start.
For this adjustment the projector white panel settings have to be adjusted properly.
The uniformity adjustment is completely independent from the TCR adjustment, so it
can be done before or after TCR.
Color Meter
Put the color meter at the center of the image.
In case of the Thoma TMF use a diaphragm to avoid overranging of the meter. In that
case make sure that the light through the diaphragm hits the center spot on the back
of the white integration sphere.
The Minolta CS1000 is used in a reflective measurement mode. Use a perfect white
projection screen. Use the manual measurement mode with an integration time of
0.2s or more.
Check the RS232 to color meter section for the correct RS232 connections to the
color meter.
