I have buy a new monitor which appears warmer in the center-right side and
cooler in the left side. I want open a case support, have you a suggestion on
how can I translate my visual impressions in data?
For now I have tried in this way but i'm not sure of the results: I set the
center point as reference and I have measured three point per three rows (see
below). What do you think about?
Thank you
Marco

Spot read needs a calibration before continuing
Place cap on the instrument, or place in on a dark surface,
or place on the white calibration reference,
and then hit any key to continue,
or hit Esc or Q to abort:
Calibration complete
Place instrument on spot to be measured,
and hit [A-Z] to read white and setup FWA compensation (keyed to letter)
[a-z] to read and make FWA compensated reading from keyed reference
'r' to set reference, 's' to save spectrum,
'h' to toggle high res., 'k' to do a calibration
Hit ESC or Q to exit, instrument switch or any other key to take a reading:
