Other Parts Discussed in Thread: BQSTUDIO, BQ34Z100-G1
Hi ALL：
I use the BQ34110EVM-796 to go on current calibration function according to the official detasheet as below:
3.3.3 Current Calibration
The gauge offers CC Offset and Board Offset calibration options to zero any residual current that may be
reported by the gauge. These calibrations are only required if the gauge does not report 0-mA current
when no current should be present.
• Select the CC Offset calibration option.
• Press the Calibrate Gas Gauge button to calibrate.
• Verify whether the current reports 0 mA. Proceed with the Board Offset Current calibration if current is
reported.
• Select the CC Offset calibration option.
• Press the Calibrate Gas Gauge button to calibrate.
• Verify whether the current reports 0 mA.
• Connect a 2-A load from BAT+ to PACK–.
• Enter –2000 in the Applied Current field and select the Calibrate Current box.
• Press the Calibrate Gas Gauge button to calibrate.
• Deselect the Calibrate Current box after current calibration has completed.
however when I have finished the current calibration,but the current acquired by the bqstudio is big different from the actual current ,who can tell me what cause the big different?
