I see none of the problems you are having though, the +/- 10 counts might seem like it's going to be out of the box but WAIT, it's spec'd by UNI-T for 1 year drift. Frankly, 10 counts doesn't mean the last 10 counts are useless
BUT WAIT! That's on the AC voltage range.
A dear 87v is +/- 1 counts from 6V onwards (not sure about the "high-res" mode), this is 0.1% +/- 2 counts from 2 to 220V rated.
Point in point, 2 counts is pretty good for a meter that actually costs 30-35$ back in china. 35USD$? WOW
BTW, the MS8218 only costs 125USD back in china.
So now you know who's overcharging now? I can get the MS8218 on aliexpress for 150USD and frankly, that's a bit of a cheat but that's global shipping prices
as i can get the MS8218 sent to singapore for the first 500g at 5$ with the following 500g at 3$ and that's the 3 day shipping service (OF course, i have no idea who my china agent is shipping with), not the overpriced EMS rubbish
But really what's wrong with this meter? It's able to measure 220MHz! IT'S AWESOME.
Many things UNI-T got right with the meter itself,
Solid, doesn't creak when you turn it, some meters creak badly especially the BK 2709.
Doesn't slip around on a laminated surface when placed flat, i have a laminated surface right here
You can turn the rotary switch around without the meter rocking left and right
Well ... the LCD has oddly better contrast than the 87v, as well as a big display
when you do open it up, you can notice the design that went into the battery slot, as well how tightly it mates up with the body
as well when you look at how the shell on the bottom part goes right in between the front part, making a good blast shielding
They mount the LCD and it stays on the board and i have seen 50$ meters with the LCD gingerly hanging off the board
Solid feeling soft buttons
Fantastic rotary switch, frankly the only reason to love this meter is for the wonderful rotary switch, nice satisfying CLACK when you turn it off or the Amps range
and only a click on the other ranges
Lightning fast autoranging
Very fast continuity
Beeper is always on BUT the frequency is just about right.
Fast capacitance measurement, trust me, most 4000 count meters get this VERY wrong.
I just feel like the physical design team are 1000 times more competent than the design team of the electronics ...
Decent probes! They only cost 2-3 bucks back in china ... Only need to clean it when new but watch out, in a humid environment a layer of oxide can grow, i've seen even on my Wavetek (Very high quality!) probes
Also to note, the wall of the meter is pretty thick, as with the thickness of the back itself, physically this thing is a beast, sort of.
But i have seen flukes with worser physical qualities, did they hire building designers or what?
I'll say the integrated holster is a nice thing (easier to access battery and fuses), as with the battery + tilting bail
And ... this is the first meter i had that smells VERY nice, the plastic's smell if both of mine do fade away, i am tempted to buy another one ... just for the smell
