And two clamp-type ammeters 60.

該轉接板20包括一第一介面22、一第二介面26、一匯流排28及兩個連接器J1、J2。該兩連接器J1、J2均包括三個可透過跳帽或線纜連接的針腳1-3。該第一介面22與該硬碟機10的介面相連，該第二介面26與該測試設備30的相應介面相連。該連接器J1的針腳1與該第二介面26的5V電源引腳相連，該連接器J1的針腳2接地，該連接器J1的針腳3與該第二介面26的12V電源引腳相連。該連接器J2的針腳1與該第一介面22的5V電源引腳相連，該連接器J2的針腳2接地，該連接器J2的針腳3透過與該第一介面22的12V電源引腳相連。該第一介面22的訊號引腳透過該匯流排28與該第二介面26的訊號引腳對應相連。The adapter plate 20 includes a first interface 22, a second interface 26, a bus bar 28 and two connectors J1, J2. The two connectors J1, J2 each include three pins 1-3 that are connectable through a jumper cap or cable.
