Averaging Data Set

[Mizan]

Hi,

 

I want to average some data for a calibration.

 

I'm logging input1 and I want to find the average of input1 for 10 seconds so I can then subtract the average from input1 to log the variation about the average.

 

I know how to log average of samples for a channel but that happens constantly. I want to press button which will then log the data for 10 seconds from that point and then find the average of that time period so I can assign it to a variable to use in equations.

 

Thanks

OK, create a sequence to do this:

 

delay(10)

global theAverage = mean(myChannel[systime(), systime()-10])

 

Then run the sequence from the button press by selecting a quick sequence action and putting:

 

beginseq(mySequence)

 

Replace theAverage, myChannel and mySequence with your own names.

 

Note this assumes that you are continuously acquiring data on myChannel.

Works perfectly.

 

Thanks
