Here are the possible causes for EEPROM read/write failure and data error
when connecting the clamp to the test board for EEPROM read/write:
A. EEPROM read/write operations are affected by the circuit of the
connected test board;
B. EEPROM read/write operations of the test board are affected by the
read/write operations of the clamp;
C. The signal is damaged by large resistance. A large resistance will be
generated when connecting the clamp to a fast communicating
EEPROM or using a long cable for connection.
Therefore, it is recommended to dismantle the chip on the EEPROM, weld
the EEPROM to the EEPROM adaptor or place in the EEPROM socket, and
then insert it in the EEPROM adaptor.
