Hello guys,
I am trying to set up DAQ system for engine testing to measure pressure, temp, torque and etc.
I am currently using NI-6211, 6212(pressure and engine parameter), and 9213 (for temperature).
So far, I am able to measure mean values over cycle such as pressure and temperature.
Then, I want to see instantaneous value by crank angle rotation (let's say every 1 CAD or 0.5 CAD).
I have encoder installed at the free end of the crank shaft which has 1024 ppr.
So, theoretically, I can measure it every 0.35 CAD.
Then, I need reference signal to define exact crank rotation angle that is TDC.
So, how to sync TDC with Encoder Z signal?
Is there any simple and accurate way to sync TDC with encoder Z signal?
Thank you for assistance in advance.

There have been a number of similar threads on the forums here. I only have time for a brief recap on what I'd do, more details can be found with more searching.
