Hi,
Happy new year!
Back to my office after holiday, I'm connecting to the remote site with several dataloggers and I state that the CR3000 displays:
Warning: Voltage calibration failure! Possible input to analog channel beyond +/- 8V.
The CR3000 ran properly before and anything was changed. Only the port Com 1 (C1 and C2)is used and any analog channel is used. I upgraded the OS from 24 to 25 hoping that the problem disappears but it persists.
Here the status_Table summary (before OS upgrade):

This message is usually displayed when >~8 V is applied to one of the analog channels.
If nothing is wired into any of the analog channels, could it possibly be a grounding issue (stray voltage running in on the datalogger)?
If you have clean power, properly grounded, and nothing on the input channels, I would contact your local support channel to discuss the issue further.
Dana W.
There can be many reasons for this issue, firstly the obvious one that the analogue channel went above 8V. The second one is as @Dana said a grounding issue. Sometimes when the ground is disconnected and the input positive terminal still connected, the voltage that ADC reads is random, above 100V at times, which naturally is above its limit so it gives an error. The third can be a floating terminal, that is, the ADC input terminal is left in floating conditions which then reads garbage values. That can be an issue in the ADC channel in itself, for example a limiting diode blowing up but that is rare.
