Some people have been asking how I collected this data with a Fluke 115.
It was an outdoor test, and I didn't have a proper multimeter data logger with me. I did, however, have my Fluke 115 measuring the current.
So here's what I did: I recorded a reasonably steady video of the Fluke's display with my phone while commenting on what was happening at each stage of the test.
Then I fed the video to
@grok and asked it to extract the readings from the display, along with my voice comments, and put everything into a three-column CSV file (timestamp, reading, comment).
Finally, I used the generated CSV data to create this plot.
