"Back in the day" long before the MR2 came along, I remember having to pull trouble codes using an analog meter. If there was a problem in the check engine light circuit and it couldn't 'blink' out a code we could sometimes go directly to the ECU and count meter swings instead. While the bar graph display on my Fluke meters definitely update much faster (40/sec) than the digital display (4/sec) it is still not as smooth and easy to see as the response from an analog meter movement.
It's much easier to spot a glitch in a throttle position sensor (potentiometer) for example while watching the smooth swing of the needle vs trying to keep up with blinking bar graph segments that are hunting back and forth.
The Simpson 260 went through several different combinations of batteries over the years. So did Triplett meters. D cells, AA cells, 9V, 15V, 30V etc.
They stopped production of the now outdated higher voltage cells here in the US quite some time ago, but luckily the Chinese market started supplying (close enough) replacements for them several years ago after they became scarce here.
I have collected a few 260's in different series with different features. I blame my late uncle Fred for introducing them to me when I was still in grade school. Loved them ever since.
