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.

EEPROM Adaptor
The EEPROM adaptor is compatible with three 8-pin packaging
TSSOP, SOP, DIP connections, and each packaging reserves three
same ports, so the device will function properly when one port is
damaged. For SOP8 packaging, the EEPROM adaptor can also work
with the EEPROM socket. To do this, place the pins of the SOP8
EEPROM into the EEPROM accordingly and then insert them into the
EEPROM adaptor.
USB Port
The USB port is used for the data communication between the XP201
