What is the point of an OLED display?
People buy shiny things. Simple as that.
I've even seen EEVBLOG members go gaga over those - people who ought to know better.
It must consume the AA batteries pretty quickly.
Yep, and it has no DC input jack so you can't plug it in when it's on your workbench. You need to constantly stop work to change/charge the batteries.
The engineers must have facepalmed when management told them to make a meter that can only be used in dim lighting and you need to charge it every other every day (
via the input posts!).
Marketing knew best though: There's a whole sector of drooling idiots who only see "color display!!!!"
The only thing missing is an Apple logo.
PS: The 'drooling idiots' aren't
necessarily the meter owners. If I was a consultant I'd buy a huge OLED meter
just so could pull it out in front of clients to show how amazing I am.
The other guy has a black and white meter, mine is color. Who you gonna hire...?
(And pray the boss leaves before the battery runs out...)
