The error value is displayed in the middle of the nixie tube. Press and hold to start adjusting numeric values. The maximum is 9, the minimum is minus 9. When the temperature exceeds 99, the nixie tube shows HHHHHH. When the temperature is below -9, the nixie tube displays LLLLLL. When no sensor is detected, nixie tube displays EEEEEE.
