BQ34110: Current calibration not working

Part Number: BQ34110

Hi,

I'm trying to calibrate current measurent on a BQ34110 with BQ Studio, but it seems nothing is happening.

My procedure is as follows:

1) Enable Calibration (CAL_TOGGLE)

2) Apply 988mA load current

3) Calibrate current at BQ Studion, Calibration tab

4) Reset device

Current reading is 981mA and does not calibrates to 988mA. 

Additional fact, I had to manually input CC Gain, CC Delta and CC Offset because default values were very different from my application. Now I need to fine tune using BQ Studio and it's not working.
