Hello Astroboy, Thank you for contacting National Instruments.
It appears that there is an issue with Advantech's AIVoltageIn.vi. If you are supposed to be measuring a 5V signal, and this VI is returning the number 0.09V then there is definitely a problem with either your DAS card or the driver that their VI is calling to return the measurement value. Unfortunately, there is really nothing you can do to correct this problem in LabVIEW other than try to scale the data to display correctly. Even in that case, you will need to know that factor of which the measurement is incorrect. More than likely you will need to contact Advantech in order to resolve the issue with the DAQ device. If you would like, you can check out our full line of Data Acquisition boards that will work seamlessly with LabVIEW. http://www.ni.com/daq Please let me know if you have any additional questions. If you get your hardware problem solved, I can help you with any LabVIEW questions you may have. Also, if you have any questions about our Data Acquisition boards, I will be more than willing to answer any questions. Regards, Bill B Applications Engineer National Instruments"
