Measuring Multiple channels at a time

Measuring Multiple channels at a time

Post by venkatgil » Wed, 09 Nov 2005 03:42:44


Hello All,

I am new to Labview trying to measure voltages and currents from a
synchronous generators using LabView7.1 abd PCI-MIO-16E-4. I want to
measure all the three phase voltages all at a time so that I can see
the phase difference between them. I modified an example for my purpose
but it can measure only one channel at a time.

Anyone please look into my file and modify it for multiple channels.

Thanks in advance

Hello Dennis,

Thanks for the info. So, I cannot measure all the three phase voltages
at a time with my DAQ Card right? But I see that many used the same
card for simultaneous measurements. May be there is some other method
to do this. Thanks once again

Hello Dennis,

This time I got the concept from your message. It doesnt matter if
there is some inter-channel delay. But the problem is I could not
select 2 or more channels by holding the shift key. It is simply moving
to another channel istead of holding to the previous one also. Is there
any other way of selecting more channels at a time. I tried also with
creating a task with 3 channels and made it global, but it didnt work.
Please let me know if it is possible.

Thanks
