I have a Samsung Galaxy S3. Besides it being a general piece of unreliable crap, the screen is also fading very fast. Two years and it looks shitty. Two more years and it is junk. Yes I know this is a cell phone, and it is on much more than a multimeter might be, but still. OLED is a technology made to fail. I will not buy anything again with OLED. I now have a new phone with a normal IPS screen and I know it will not fade and change color over time like the OLED. There have also been many reports of people who have had their OLED display meters fade to unusable. Stay away from OLED for something you want to last.

Yes, I actually bought mine in the UK at http://www.tester.co.uk/hioki-dt4282-digital-multimeter

It arrived in the US in 3 days. Awesome dealer!
If you don't mind posting it, what did that run you shipped?

I ask, as importing it from your UK seller would still be less expensive than TEquipment.net after the discount & free shipping (here).   :-//

So, how you define professional multimeter?

It's Fluke's Claim! Most ACCURATE handheld meter in the market.

Behind the Gossen Metrawatt METRA HIT 30M, of course.

yea, rightly said, OLED, a selection, buyer needs to think many a time before getting one....ONLY 8 Hrs of battery support once charged fully  :-X . Even no support for on daylight reading. Think think think :o

The modern OLED Keysight meter has much better battery life than the old design.
But still LCD for a meter is the only way to go.

Can an Oscilloscope be an Alternative choice to DMMs??  Share your thoughts & views!!
I can answer that one: NO!

As scope is no substitute for an a basic DMM.
The DMM in near instant to turn on, is small and compact and can moved anywhere for convenient display, has proper safety features (and floating), and can do things the scope can't, like current, continuity, diode, capacitance etc.
Silly to even compare the two, both are essential instruments.

Dave,

Can you pl suggest us an industry standard very Accurate and WIDE range LCR meter?? Cost no bar!!

Another possibility would be the hewlett packard 4194A. This is a impedance-network analyzer which does more than just LCR.

Measuring LCR, impedance is not as simple as it may initially appear. There are many factors that can easily affect measurement accuracy and expected results. For this reason, no single instrument is ideal for all conditions. Spend some time with this hp app note:

My personal issues...

- I often forget to power of the devices, so I accidentally use the DMM in resistance mode when the circuit is powered on. This means most DMMs end broken or need constant fuse replacement, very often both things happens.
- I need autorange, because ranging drives me insane most of the time.

I tried to change my bad habits, but it's a PITA to change them. I'm very absent minded...

Would I need a good DMM + Transistor Tester project be a good combination for me? I can learn whatever is needed, but I need inattentive-proof equipment :P

Kind regards.
