1. Click the "Non signaling mode" button.
2. Click the Check Connection button.
3. Check the "On" box located on the bottom of the ADC Meas(urement) box.
4. Change the power supply PS-1 voltage from 3.7 V to 4.0 V
5. Monitor the vbat ADC value in the ADC Meas. box.
If this average value is outside the range of 3800 to 3400, then the unit has failed.
6. Enter the average vbat ADC value into the Battery ADJ Excel sheet in the vbat=4.0V field.
7. Change the power supply-1 voltage from 4.0v to 3.3v.
8. Monitor the vbat ADC value in the ADC Meas. box.
If this average value is outside the range of 3100 to 3500, then the unit has failed.
9. Enter the average vbat ADC value into the Battery ADJ Excel sheet in the vbat=3.3V field.
10. Change the power supply voltage from 3.3v to 3.7v.
9.3.5 Current AD Calibration
Note: For this testing PS-3 must be able to sink current. PS-1 also needs to have
an extremely accurate current sourcing capability. Agilent 66311B power supplies
or equivalent are recommended for this calibration.
1. Connect power supply PS-3 so that it supplies 3.7V to VMAIN
2. Change PS-1 so that it is set to 5V with a current limit of 200mA.
3. Monitor the curr. ADC value in the ADC Meas. box.
If this average value is outside the range of 2400 to 2900, then the unit has failed.
4. Enter the average curr. ADC value into the Battery ADJ Excel sheet in the curr=200mA field.
5. Change PS-1 so that it is current limited to 800mA.
6. Monitor the curr. ADC value in the ADC Meas. box.
If this average value is outside the range of 3100 to 3600, then the unit has failed.
7. Enter the average curr. ADC value into the Battery ADJ Excel sheet in the curr=800mA field.
8. Change PS-1 back to 3.7V with a current limit of 3A. Disconnect PS-3.
