Multiple Value Searches at Once

[IsaacNZ]

Hi all, 

Trying to make a lot of comparisons to sense check a large amount of data, for instance is the flow signal flat lined when greater than 0m3/s?

At the moment I am doing the following:

• Creating a derivative of the flow signal to know whether or not it is flat lined
• Carrying out a value search for when flow is > 0
• Doing another value search for flow derivative = 0
• Finally a composite condition to see when both value searches

So I'm wondering if there is a simpler/faster way of achieving the same result in fewer steps as I will be needing to do this a lot. 

 

Thanks!

Hi Isaac,

While it's technically the same steps, you could do this all in one Formula with:

$signal > 0 and $signal.derivative() == 0

Note that in versions below 49, you will replace "and" with "&&" in the above formula.

Ah thanks so much this is exactly what I was after! I was using "and" instead of "&&" when trying this earlier. 

Cheers
