content: It’s not the best display on the market, it’s a little dark when not backlit but it’s backlight when on is far superior to that of the top end Keysights. The other issue is the auto shutdown and auto backlight dim times are too short. Other than that it is a stunning meter, it holds accuracy better than my Keysight meters and it’s the closest thing that I have found to a bench meter experience in a handheld. It feels and performs like a high end Japanese built piece of test gear.

content: Quote from: BravoV on November 01, 2019, 07:22:14 amI would say not. If it was the zebra strip the digits would be uneven, not uniform. Plus other people are seeing the same thing.What's needed is a contrast adjustment. Is there a potentiometer inside for that?

content: Quote from: Synthtech on November 01, 2019, 06:59:15 amDT4282 does have amazing performance, in many ways more than other high-end handheld watches of the same grade (including FLUKE289,U1282A, etc.), stability of DCmV range 1uV resolution, ultra-high speed peak mode, resistance function is better, in terms of accuracy, speed, stability is first-class, and has excellent temperature drift index. However, I don't like the fact that its AC range shows zero within 1000 words, as the OP application DT4282 below cannot do.https://www.eevblog.com/forum/testgear/suggestions-for-a-dmm/It has other drawbackshttps://www.eevblog.com/forum/testgear/hioki-dt4282/

content: Indeed. It’s in a class of it’s own when it comes to precision and stability. It’s capacitance autoranging is also much faster than the Keysight. It lacks the immense number of programmable options for it’s functions that the Keysight has, it’s not as customisable but it is a formidable lab meter, very high reading confidence.

content: I've been using my old Fluke 8060A lately just for kicks (plus I really like having a dB reading on it), it has one of the best contrasts I've seen on an LCD screen.

content: Quote from: Fungus on November 01, 2019, 05:42:49 pmIt's strange, the display of a high-end meter doesn't have a good contrast instead. Why?

content: Doesn't the contrast of lcd mostly just relate to the viewing angles?eg see below.

content: Quote from: VK5RC on November 02, 2019, 03:20:59 amWe should take the normal viewing angles as the standard, your second image is not the normal viewing angles, We can see that the worst performing is DT4282 still

content: Quote from: hgjdwx on November 02, 2019, 03:42:43 amIf it really bothers you so much than don’t buy the meter, choose something from another company. The Hioki’s contrast has never been an issue for me and I use it a lot.
