Z1102 ECG Board Self-test
• Upper-level test item
None
• Test Items
The program controls the PC module to read the ECG board register through the USB port
and check the A/D collection and Voltage33 power status.
• Test failure analysis
If the test result is Error, the drive is abnormal.
If the test result is FAIL, the ECG board is faulty.
• Troubleshooting suggestion
1. If the test result is Error, restart the device and re-perform the self-test. If the problem persists,
restore the device.
2. If the test result is FAIL, replace the ECG board.
Z1201 Communication Test for the Battery Management Board
• Upper-level test item
MF board in-place test
• Test Items
Check whether the UART connection between the SM ARM and the battery management
board ARM is normal, and read the firmware version and board ID.
• Test failure analysis
If the test result is Error, the drive is abnormal.
If the test result is FAIL, battery management board is not in place or not assembled properly.
Re-plug it. If the test result is still FAIL, the UART connection between the SM ARM and the
battery management board ARM is faulty.
• Troubleshooting suggestion
1. If the test result is Error, restart the device and re-perform the self-test. If the problem persists,
restore the device.
2. If the test result is FAIL, re-plug the battery management board. If the test result is still FAIL,
replace the battery management board and then the main board.
Z1301 Battery Communication Test
• Upper-level test item
Communication test for the battery management board
• Test Items
The program detects whether the battery is in position through the I2C interface of the battery
management board ARM. If the battery is detected, the program reads the version and battery
serial number.
• Test failure analysis
