Table 3.4 TEST Mode Functions List
Function Description Reference
Communication test
Reads data from the ID tag.
Checks whether a sequence program, antenna, or ID tag caused a read error
when a data read error occurs with an ID tag.
Section 5.1.3(2)
Distance level
measurement
Checks the margin with respect to the maximum communication distance
(potential) of the installation distance of the ID tag.
