Description of the variable delta_calibration_temp_x:
The ADS1255 performs a self-calibration, if the temperature of the PCB (2420
h
) deviates more than
the value specified in delta_calibration_temp_x from the last_calib_temp_x .
Value
delta_calibration_temp_x
Function
0
no automatic self-calibration at deviation of the temperature
0001

h
automatic self-calibration at exceeding the allowed deviation of the
temperature
