I am doing data acquisition using Advantech Usb4716 and Labview 8.5 to measure pH. Need help and guidence in programming to monitor the ph. I'm undergraduate student and know little on Labview

Hi 0166024552,



1. Since you're new to LabVIEW, you should get through some tutorials, http://zone.ni.com/devzone/cda/tut/p/id/7466, first.

2. VIs to control 4716 from LabVIEW is available on http://support.advantech.com.tw/support/DownloadSRDetail.aspx?SR_ID=1-29WTFD

3. Even 4716 has a VI, but its performance and comfortable may not be as good as NI's one. If you get stuck with 4716, you may consider USB-6218, http://sine.ni.com/nips/cds/view/p/lang/en/nid/203092, which has a similar specification.

Hello, 

I have to work also with the DAQ Advantech USB4716 and I use the LabVIEW's user libraries with Windows Xp to program it. In fact, I would like to make a mechanical experiment which enables to measure the displacement and the strain applied on the skin while I send the voltage control of the motor which enables to obtain loading/unloading cycle of the skin. To do it, I use an analog input of the Advantech USB4716 DAQ to control the motor, and measure the displacement and the strain with 2 analog inputs. So, I would like to know if it is possible to use simultaneously one input and many outputs on the Advantech. I have already tried to program and test, I send the voltage control, but I didn’t manage to measure the mechanical parameter. In fact, it doesn’t work. I joined my program if you want to see if I have a programming problem.

Thank you in advance for your answer.
