我使用DAQ USB-6361搭配LabView抓值功能來抓取電壓訊號,一次2000筆
但前陣子再一次重新使用時發生問題,問題點:
為何之前可以運作程式,突然就不行抓值
第一 是否是DAQ傳輸線的問題(接腳看不到有無斷PIN,DAQ使用兩年)
第二 是否是Labview軟體DAQ訊號程式的問題(基本上之前好好的都沒去更改)
MESUREMENT可以讀到值,程式也可以產生出記事本,不過記事本的值2000筆卻都是0

請問是否有用示波器或是三用電表確認過待測訊號是否正常?
如果正常的話,請先至NI-MAX (Measurement & Automation Explore)中確認USB-6361的AI功能是否正常,並且正常取到值。
如果MAX中正常,但LabVIEW程式中卻不正常,那就有90%以上的機率是LabVIEW程式撰寫的問題了。
