公司DC發電機測台使用PCI6259卡,目前校驗人員執行校驗程序時發現,在未輸入外接電壓時,校驗測試項目已顯示有電壓值(正常應0V),經檢測隔離拆除DAQ卡外接線路,銷驗測試項目仍存在電壓值,請問有何方式可測試DAQ卡好壞?是否提供檢查建議,謝謝!

您好,請問顯示的電壓值是多少?
在未輸入外接電壓時,電壓值不一定為0V,如果要測試是否正常,先輸入指定電壓,再看顯示的電壓值是否正確。假設想讀取0V值,可以考慮把AI接AI GND。

感謝回應,不管外加電壓多少V,顯示電壓值無變化,後來上NI官網(http://www.ni.com/download/daq-diagnostic-utility-2.1/2244/en/)下載DAQ測試軟體(DAQ Diagnostic Utility 2.1 )測試結果是類比輸出故障,與測台故障情況相符,確認DAQ卡故障,謝謝!
