I'm not sure why you had issues with your Fluke 87V for a simple measurement, my 20 year old 85I reads true today as it did when new per the original calibration data for series 1; I just spent some time checking its calibration with some new equipment I have that was calibrated in March and April this year.
I saw the 70D video in the past, while it could have just be a 'fluke'
if you read the comments on the video, he was not alone.
There are other favorable reviews elsewhere though, particularly those looking for a low cost data logging DMM, which is helpful if it were reliable and read accurately. So I have some interest in a meter than works like Fluke but isn't in its price range, but I'm not convinced you'd want to invest time and energy collecting important data with this Uni-T. I wouldn't hesitate to buy it for low voltage or DC use in the field, but I think you can do that with a cheaper DMM.
The spec sheet is a bit misleading:
http://www.uni-trend.com/UT70D.htmlIf this is true, for an 80,000 count DMM its accuracy is more closer to 8,000 count. The last digit has little value.
For e.g.: specs report 0.05%+10 digits in the 8V range [ but the manual Kiriakos shows that at 8V its really 20 digits.]
8.0000V ~ 7.9960-8.0040, + 10 digits ~ high as 8.0050. That's quite a bit of variation unless you ignore the last 2 digits. Likewise, the reported accuracy of the ACV and other ranges to a high of 20-120 digits, reinforce the last 2 digits unreliable, at worst.
The manual page 34 shows what Alm already suggested, its full scale represents the same scale as the digits, so in this example, it would be 8v, and the scale represents 8/10 for every digit. Luckily most folks use the analog scale as a relative reference or real time trend, rather than to measure a value.
The penultimate voltage range is 800V then finally 1000V, which seems like a unusually small increment given the way a DMM scale is made. I think this is more to keep in line with the limits of CAT III safety which limits input at 1000V AC or DC, for transients up to 8000V.
FWIW you won't get this issue with an reputable DMM, like a Fluke that you'll have for a lifetime.
I do not have faith in this "marketing statement" .
especially by having in mind , the negative and poor behavior of Fluke , to any one who got an used meter....
If I was an manufacturer of DMM's, I would use also acceptable "middle cost" FUSE solutions.
Comparing apples with apples , the 300$ UNI-T will have no deference from the FLUKE 87-5 .
Oh yea this fantastic video ... will blame the UNI-T for a life time ..
I will have to make my own video , to blame the FLUKE 87-5 about it poor performance as frequency meter ..
I was testing my own tone generator , and I had to amplify the signal with 5W amplifier so to get reliable readings ..
With 0-600mV input level , it should be hyper sensitive as frequency meter too !!
Or ...
I had to use the output of the tone generator as input on my amplifier ( square signal) , so to have acoustic output,
and another output of my generator ( sine signal ) , as input for the Fluke !!

I have 50/50 % , love & hate feelings for the top Fluke , thats why I consider my opinion as less biased.
