--- Quote from: luma on January 27, 2022, 01:43:32 pm ---Let me try another approach. Here is a screenshot of the forum as of a couple minutes ago. In red, I show the 17 threads which concern something with a color display. In black, there are 5 threads about devices which don't (and two of those are about the same device). Threads which aren't about one specific device aren't counted. The test measurement industry seems to think they're useful somewhere.... --- End quote --- And how many are handheld multimeters of those?? |

Almost none, which is exactly the point. DMM market is stuck with UIs and display tech from the 70s. |

Benchtop multimeters are not handheld. They are not battery powered and use as much as 20-30 W (or more) to run. They are meant to be used at arms length, at room temperatures... By operators that have time and skill to operate complicated menus.. And you're completely missed the point. Point is there are not many GRAPHICAL multimeters (even B/W screen ones) at all. And that is not because nobody is "modern enough" to make them. 10-15 years ago there was a moment when there was quite few graphical multimeters at one time. And they all stopped being made, because there was NO DEMAND for it. There is no real market. They were big, bulky, heavy, had rechargeable batteries that lasted only short time. They were powerful, smart devices and nobody wanted them in handheld format. Then benchtop meters started getting those graphical screens, and that was well liked. You could do all kinds of advanced stuff: histograms, data tables, plots the whole nine yards.. And that is what you buy to work at desk. If you need to carry it around, you get handhelds. In a format that is, well, handheld. And it is not stuck with U/I and tech from 70ies. It is ONLY low power, high reliability, large temp range display technology in combination perfect for handheld meters. And it measures values that are expressed numerically. So it shows numbers. What do you need, some Teletubbies display that will show flowers for good voltage and little poop icon when battery is dead? You're confused. Manufacturers of the world will manufacture ANYTHING.. Any crap, as long as there are those that will buy it. Fact that nobody makes it IS the writing on the wall... |

nothing better than a good (optionally backlit) black and white lcd. - highest contrast possible - sunlight readable - readable in twilight/ dark ( backlit) - no pixel flickering / refresh - sharp font ( no dithering ) - small characters are not restricted to pixel size. the character is a vector etched during manufacturing of the display now, if you are going to go graphic : give me trend plot and waveform view so i can look for net disturbances. i don't need a scope but i would like to see at least 100ks/s waveform view so i can look at dimmers and potential interference on powerlines. something i do not like doing with an oscilloscope... |
