3.9 Temperature Calibration
This feature calibrates the internal temperature and the external temperature sensor if the source is set by
Operation Config A [TEMPS]. A known temperature must be applied to the device for temperature
calibration. The calculated temperature offset is written to the corresponding location in DF. The
temperature offset is represented by an integer that is a single byte in size and can be written to the
appropriate location in DF without any intermediate steps. The host system must ensure that the fuel
gauge is UNSEALED.
NOTE: a) The step labeled Obtain avgRawTemp refers to Section 3.7, Obtain Raw Calibration
Data.
b) When using bqStudio, ensure that the selected calibration of Internal or External
temperature matches the setting on the [TEMPS] selection.
