I have many different sensors (>>100) with many Data (continuous) each (>1mio) and update these each week.
Sometimes these sensors "glitch" and send wrong data (below/above a low/high threshold)
I want to calculate the number of "glitches" per week (KW=categorial) and need a fast way by JSL code.
Example: negative data for this sensor should be detected (low threshold 0)
My Solutions are too slow:
1.) I set the threshold limits as "specification" in column properties and then perform process capability
"Observed outside" Spec per KW is the desired value, but it is quite slow
2.) Brute force: each row, each column, manual check, adding each cell (Excel style) takes forever.
Is there a more efficient way to do this?
