Should Handheld multimeters have color LCD displays?

BLE is super-handy for multimeters, there was recently a fairly low-cost (£50 from memory) Multicomp meter with BLE which I really wanted but it was out-of-stock. 

I've got a couple of instruments with scope-like displays but monochrome (I had an old digital 'scope with monochrome display too, and it worked well apart from it could never have features like persistence on CRT scopes, so colour becomes a lot more important then). One instrument with nice UI is a chart recorder, it has portrait-mode display : ) so that the traces can be nicely separated in monochrome.

A nicely laid-out display, and perhaps a menu or more buttons could be nice in a multimeter, since the complex features get hard to recall how to configure.

Colour would then be icing on the cake, but if it could be bright and readable : ) 

The BLE DMM to PC pioneer is in this thread ;)  MP730026 DMM BLE Tutorial using Python  still works

That's the one, thank you! And nice article by baldengineer 

I just checked, it is back in stock, and really good price currently.. £32 + tax. I have ordered it, if I'm lucky I might receive that in time to try it before the weekend.

Do you still need a rotary selection switch? I don't know...

For a handheld, I still think it's the ergonomic winner.
Meter in one hand, turning the switch with the other. Just looking from the corner of your eye is enough to see if it's correct (if you know your meter)

The DVMs are a pain to change the 9v battery, but most models have auto-shutoff, and the battery lasts a pretty long time. BLE seems to work well and useful for higher voltage stuff greater than 230V, usually I'm not messing with a USB & PC when troubleshoot using a dvm. 

How about a touch screen - operate with just one hand?

There is no denying I got a warm fuzzy feeling when I powered on the scopemeter for the first time! But who doesn’t like getting new shinny things, or better yet, new test gear!
Ohh Scottie what frequencies does your induction cooktop switch at?
Let me make a loop antenna with my scope probe and measure it with my OWON HDS242 scopemeter:

Between 19 kHz and 36 kHz. LOL

I definitely love having a bright color display! Will I love the battery life that is the question!!

are yoou sure that the signal form isn't an aliasing artifact?

(what I actually wanted to say: cool meter!!!!)

Yes lol, I had tried to take other screen shots but do to user error, I only later I realized the meter doesn't automatically increment the image finename number (and you only seem to get 4 bmps lol)

You can see the drive amplitude has a 120 Hz envelope (8.3 ms) to maintain a near unity power factor:

It may work excellent too. I have some kind of test bed:

The Keithley DMM6500 has colour display and touch screen. Not a perfect example because it's a bench meter. But in essence a DMM with colour and touch.

I am fluent with operating it, and think it has a good interface. But I need more attention/focus, and typically am spending all attention to the screen and my finger's actions, when I manipulate the meter. Also for simple actions like a range change. 

(same with a physical calculator, and a simulator of that very calculator on my phone's screen: I am an order of magnitude slower on the touch screen)
