"figured a bit more out with the my identifinder, it is complaining about the backup battery being dead (seems to be a smaller battery soldered in the unit) and is loosing its calibration on each bootup. From what I have been able to gather, the cs-137 calibration is mandatory at first boot but them it switches over to the blue led calibration on subsequent power cycles. That probably explains the smaller check source: on the standard it runs a 30s calibration with the 15nCi source at each boot, whereas in the ultra is runs a 180s calibration on the 3nCi once to calibrate the blue LED and then does a blue LED calibration (every 5s apparently)

there is also some sort of background subtraction that it does with the check source, the cs-137 spectrum peak doesn't show up in the downloaded spectrum. If you put an additional source you can still get counts there so its isn't just completely blanking out the area. not quite sure how it works, must just selectively delete some counts"

"I did end up ordering a main battery for mine, they are still available from FLIR in both nicad and removable battery (takes 4x AA) version. Almost would have been cheaper to buy another burner unit, it was almost $250 with tax and shipping"

 hmm so there is good news and bad news, the good news is the battery is a pretty lithium primary cell i a 'cr-1/3n' package from FDK. The bad news is that there aren't any available from the usual digikey etc with tabs

 messing around a bit with the software, it is pretty basic but mostly functions. basically, from what I have been able to gather it doesn't actually control the unit in any way but it lets you pull the data off. Seems to be working to manually set up an acquisition and then clicking the 'load actual spectrum' button which grabs the current counts and displays it (it adds to the currently displayed spectrum). The software itself has that early 2000s clucky vibe (not unlike the skyscan...) but was able to make a plot
