bq40z80在没有外加负载的情况下显示-10~-20mA的放电电流?如何校准?

Other Parts Discussed in Thread: BQ40Z80, BQSTUDIO

直接进行cc gain校准,使用3A校准,发现在其他放电电流情况下,偏差还是较大?能否通过CC Offset Calibration和Board Offset Calibration校准静置条件下的电流?在bqstudio软件上如何实现CC Offset Calibration和Board Offset Calibration校准模式,已经查看bq40z80 Manufacture, Production, and Calibration 文件,但是还是无法在bqstudio上实现。
