Test gear and eye candy bling don't mix
It's unfortunate you had to find out the hard way
Care to elaborate?
I don't own any OLED devices, and understand that OLEDs have a bad lifespan track record so far. But the
concept of using color (or 'eye candy') in a DMM display
isn't inherently bad. If fact, I'd love to have a good meter with this kind of bling if the problems of lifespan, decent battery-life, etc are resolved. A good color display should be easier and quicker to read, and could be quite a boon in logging multimeters to display trend information more helpfully.
We rely on known brands for a reason, as a shortcut for helping to determine reliability and quality. One would certainly hope that a reputable company like Agilent/Keysight wouldn't be providing such features as mere 'bling'... but as something that was carefully engineered/tested to provide utility along with reliability. That trust seems to have been misplaced in the case of their OLED meters...
