  Hi, I have 2 aranet4's and I updated the firmware on each one.  As they sit next to each other, their readings are vastly different- 1036 vs 652.

   

  Should I do a manual calibration of one? Or both? Or, reset some other way?  They each are factory calibrated so I'd hate to lose that if it's not necessary. Thanks.

  Hi!
  
  Make sure you haven't accidentaly breathed on them and let the Co2 level settle, over an hour or so.
  If the measurments are still more than ~60 ppm apart then do a manual calibration on both of them.
