real time data acquirring

Hi Kate B,

Thank you, Kate. U help me a lot in this project. Now i'm able to acquire the voltage and current already.

But i have another problem need of assist by you. Hope you can give me some comments. 

1.) This is the case. When case structure active, the waveform of current do not monitor out, but it only able save the waveform to the indicated file. What can i do while on save the current waveform to the folder but also monitor out the current waveform. The Vi will be attach at here.

THank you

The only reason I can think of is that your current is out of +-4mA while logging current.

Set your current graph to auto Y scale to confirm this.

Hi Kate,

I have a question.

Is it "Write Waveform to the File" vi, it only can save a certain period of waveform to the file? 

example i want to save a waveform from 0-10s, but this vi only able to save 0-5s, then from 5s-10s, it will asking you whether want to save at creating file..

If not, what can i do to solve this issue...?

thank you and best regards.

Hi Kate,

As per attach  at here,

when i wired the  "write waveform to data" vi and "write data to measurement vi" as in attachment, they both only can save a certain period data only.

do you have way to solve it?

Set If a file already exists to Append to File.

Hi Kate,

How to show the all the waveform data save from the "write the waveform to file" vi by using the "read waveform from file" vi since i only ablt to read a certain portion of waveform only?

Do you have any idea or method that could help you to save first 10s data after the power start supply o reset?

thank you and best regards,

Hans
