I'm trying to make single shot measures, with the 'spotread' utility and my X-Rite DTP92, but I always get the same values :
Result is XYZ: -0.000000 -1.997025 -0.000000, D50 Lab: -18.039055 77.754547 -31.101819
I'm sorry, I have no idea. You'd need to be a bit more explicit about what you are actually doing. What does -d show ?
This is what I get:
spotread -i92 -e
About to init the comms Established comms About to init the instrument About to enter read loop Place instrument on spot to be measured, and hit [A-Z] to setup FWA compensation (keyed to letter) [a-z] to make FWA compensated reading from keyed reference 'r' to take previous reading as the reference Hit ESC or Q to exit, any other key to take a reading:
I place the '92 on a white part of the screen and press return:
