    TH2523 Operation Manual Ver1.0 Chapter 8 Handler Interface TH2523 AC milliohmmeter equips with a Handler interface which is mainly used to output the sorting result. When the instrument is applied to an automatic component sorting test system, this interface will output the handshake signal and the sorting result output signal. The sorting result output corresponds to the comparison result output of the current comparator bin.
