テスター間のグランド・パスにより "基準値の設定" に失敗する - DSX CableAnalyzer

This article applies to both DSX-5000 and DSX-8000 copper modules.

If you encounter this message while you are setting reference over the copper adapters (DSX-PLAx04) link adapter and (DSX-CHAx04) channel adapter), it usually means that the USB cable is still connecting the Versiv main and Versiv remote when you attempt to set the reference.  Disconnect any other connections between the Versiv main and Versiv remote other than the link adapter into the channel adapter and try setting the reference again.
