Read and save voltage measurement

[mshaglouf@yahoo.com]

Dear NI Technical Support personnel,

I am using LabVIEW Signal Express 2.5 to measure the voltage with time using USB-6211 . If I want to record the voltage using a sample rate of 1000 Hz. for a certain time e.g. 2 hours. Shall I start with Record or Run if I want to save the data? If I start with Run then I Stop would the data then be saved if I click on Record?

Thank you

Hi,

With LabView SignalExpress, you can record data by either pressing Run, then pressing Record or by simply pressing Record only. In both cases, it should ask you to confirm which channel you want to acquire data from before the recording process begins. Data won't be recorded if you were to press Run, wait two hours and then press Record, as no data will have been recorded in the interim period.

I hope this is of help to you,

Dan
