I noticed that many years ago while debugging some issues with the ECU on the MR2. I was looking for a rather long "pulse" ... several tenths of a second ... and the digital meters would not show anything as it did not have time to stabilize at 12v before returning to ground.
Radio Shack was in the process of closing all it's stores but the one a few miles away was still open and had a "less than $10" analog meter on hand. Got it and was able to see the needle swing up (no idea how far, but it did swing!!!) and then return to zero so the required information obtained and I could move further down the Toyota trouble shooting guide.
Beats having to drag the oscilloscope out to the garage.
The digital I have now has an "analog" bar on the LCD but I am not sure how "fast" the bar is. Does it take as long as the digital display to calculate what the value is and then determine how many of the bars should be colored in? Haven't tried it so I don't know.
