Current Duration Measurement

[jue]

Hello all,

I am new to labview.

I want to measure the time of duration of the current that comes from the input of my DAQ input channel, and use this time to make decision.

How do I measure the the time duration?

Thanks!

Be specific to your question do you want to measure the time duration of current? What does it mean please explain a bit more.

I have an on/off switch to control the current input to the DAQ. And I want to measure how long that switch stayed on, in other words, how much time did the current flow. And in Labview, I want use this time to be a variable to program. For example, if the time is >1s, x>y, if time <1s, x<y. How can I measure this time. Thanks!

If you are using DAQ in host you can take the system time (Elasped time). So when the switch goes high start the timer and stop it once it goes low.

Time in seconds indicator gives you the time interval between the switching action

Good luck

Thank you very much!

What should I do if I want to see the instant elasped time?
