Confirmation &
Adjustment
- 1. Apply 2.3V ± 0.005V between BATT(+) and BATT(-).
2. Execute the command "Backloff", then “readbatt“.
3. Confirm: 29 returned value 36 (Hex)
(If the returned value is within the range, no need to do step 4 and 5.)
4. If the reading is out of range in step 3 above, adjust the battery monitor
excuting command “wreeprom 00 01 01 XX”. (XX is the reading at step 3.)
Then excute command “wreeprom 00 36 01 YY”. (YY= XX - 0E)
