How to easily get the peak and through value from waveform

[Albert.lu]

Hello,

Is there a solution to easily get the peak force and trough force from wavefrom got from DAQ?

Thanks

There are a couple of functions you could use.

The major questions are:

1. Do you want to have an absolute maximum value (e.g. 20.6) ? If so, is that only in a certain selection (e.g. 5.01 in range of distance 0.4 to 1.2)? If no absolute value, how do you calculate that value (e.g. average of 3-5 samples)?

2. What is a "trough force"?

3. There are a couple of functions computing average values. Have you already reviewed which one looks promising for you?

Also next time you might want to attach a VI rather than an image....

The search peak function should be able to do the job. read the help about it.

It will do a square fit of a specified window length to detect a noisy peak. A good start would be datapoints over about 0.5mm ...
