remains after the APR is executed, perform the manual RPN compensation adjustment.

these three channels, be sure to perform the ABB three times.
. The log of the address data of RPNs that have been compensated is updated each time the APR is
performed. RPNs that are not detected with the APR function fi ve times in a row, they are excluded
from the scope of compensation and their data is deleted.
