QuickDAQ software connecting to a new hardware

[xiaobao]

hello

I have purchased the fft portion of the QuickDAQ, but there is only one screen (the time domain) shown I could not see the spectrum screen. please help on how to bring both screens up. 

also the initial set up for the accelerometer and data translation "DT9837" would require steps of setting up?

 

Thanks..

Hello @xiaobao.

Please refer to the QuickDAQ user's manual, page 66.  Enable the Visible Plot option.

With regards to an accelerometer configuration example, please refer to page 268.

yes I had the same screen as above. the check mark on the input device. but page 268 showed a different screen I could never get from the program. "IEPE channel" where do I get that?

[Fausto]

In order to access the IEPE Channels Configuration, click on the Configuration menu option, in QuickDAQ, followed by 'Input Channel Configuration'.

yes, I followed, I only get "analog input channels" why?

my request is simple: the top screen I want to show "g" gravity in vertical and "t" for time domain .  The bottom screen I need to have "amplitude" for the vertical axis, "Hz" for the horizontal axis. this is the conventional view graph for FFT. I don't understand why the Hz becomes vertical axis that's strange. please help. thanks.

Hello @xiaobao.

The bottom plot in your screen capture shows the tachometer data.  The axis data is as expected for QuickDAQ; reference pages 115-116.

ok, I don't have the tachometer and I don't need it. 

Can I plot the FFT curve on the bottom screen, how to bring it up and set up for (amplitude=vert axis, Hz=horizontal axis? )

The top screen I have "g" so it's running a straight line for me now. how do I change the input so that I can see the wave (displacement) lines?

Hello @xiaobao.

I recommend you review the 'Acceleration Measurement Example' in the QuickDAQ User's Manual; pages 268-282.  It will lead you to your desired display.
