I tend to have problems when I'm using the t-probe and there are fluorescent lights nearby. I'll shut the lights off and the t-probe works better, but I need to see!
I've had this issue before with an AT-901 and an older T-probe, all of my other co-workers though I was crazy. What's odd is that it was used in the same room with the same lighting all of the time, but if it would placed in a specific spot in the room, it would have trouble taking points. I have not noticed this issue with the AT-960 and later model T-probe.
I have been to the lab where they are calibrated, and it is lighting by florescent bulbs, nothing special.
