BQ34Z100-G1: BQ34Z100-G1 Voltage Calibration Problem

Part Number:BQ34Z100-G1

Hi,

I am using BQ34Z1xx EVM and connecting it to bq studio using EV2400 over I2C .Iam unable to calibrate voltage parameter. I am using ~ 37V Lead Acid pack (3 batteries in series).The battery studio is showing me the pack voltage as 25.77  but the true voltage is 36.8 V.

Here is what I have done.

-bq studio 1.3.54 ,ev2400 Version 0.18

- have set the VOLTSEL bit, put a jumper across 48V on J2,put the voltage divider value as 39000mV in data memory register under calibration

Any help on this topic will be appreciated.

Thanks.
