encoder and speed sensor

[Andy-C · Accepted solution]

Have you tried using counter 2 or counter 3 in your second DAQ Assistant function? 

You are using the large range 2 counter method in both of your DAQ Assistants, but the 6351 has 4 counters and should be able to read 2 encoders this way. Note that unlike other measurement types, only one counter measurement can be used in a single task. You must therefore create a unique task for each counter operation. Does the error appear using ctr2 or ctr3 for the second task?

is there a better filter than median filter for this application?

I'm glad you were able to get your measurements working!

As for your follow-up question, you may have better luck posting a new thread over on our Signal Conditioning forums located here.
