time input response

[alanled]

I have a Hydraulic solinoid valve energised by a digital output on my DAQ device (USB 6012)  holding a pressure measured by a transducer which is read into an analog input channel. I have to measure and plot the time taken from denergising the solinoid valve for the pressure to reach 0 i.e 0v. the average time for this is 70mS, will a elapsed time vi be good enough for this or do I need to use something else. Any guidence will be most welcome.

Look in the

Help\Find Examples\Hardware Input and Output\DAQmx\Analog Measurements\Voltage and then pick for example the "Cont Acq&Graph Voltage-Ext Clk-Dig Start.vi" as a starting point.

The measured voltage is your pressure sensor

The Dig start is you digital I/O that drives the valve

Modify what has to be modified, but use this one as a start...

PS: There's maybe a better one in the list but I didn't check them all
