I was looking over my documents and found the original calibration page that was shipped with my instrument. It recommends that I should have the i1Pro re-calibrated after about 2 years. My instrument is about 5 years old now.
What is your recommendation regarding re-calibration? How can you tell if it is needed? My instrument is always stored in in the padded case except when in use.
tks, louie
Use i1Diagnostics v2.5.1 to check your i1Pro.
You can post the result log file here for diagnosis.
Download here:

Here is the log file output from i1Diagnostics. Please take a look and see if there is any indication that I should recalibrate.
tks, louie

*** PASS ***The numbers on your Emission Test seem to be a bit off.
In particular, it looks suspicious to have your Black measurement have negative numbers for X and Y. Gray and Green look pretty different too.
I don’t really know how to interpret the numbers, but your numbers seem to be quite different from mine:
Patrick,
I have contacted Xrite support to see what they say about the results of test. I will keep you posted.
tks, louie
Can you tell me exactly what the emissions test is. I just ran i1 diagnostics on my i1 Pro because of some strange behavior in my profiles and it failed the emission test.
An i1Pro device can measure reflective light (light bouncing off of a paper for instance) and emissive light (light emitting from a computer display). The i1Diagnostic program runs the device through its paces on all these functions. The emissive test would not include any self-illumination, so you might try it again and make sure the device is on the screen when it is supposed to be and that it is well-settled in the in the cradle when it is supposed to be.
I ended up sending in the log files. And, it looks like I have a lamp issue. Fortunately the device is still under warranty. Thank you for your quick response.
