Why does the CAL symbol appear on my Dynatron AG Test Equipment?
- DDominique PageAug 10, 2025
If the CAL symbol appears on your Dynatron AG Test Equipment OxySpy, it could be due to a few reasons. It might be because a new battery or a new O sensor has been installed. Another reason could be that the calibration was not successful. In any of these cases, you should calibrate the OxySpy.
