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:

  read_sample returned 'No error' (No error)
  Result is XYZ: 48.450000 48.940000 56.810000, D50 Lab: 75.413986 3.481909
