I am a frequent Taobao buyer and in my experience if you're buying Chinese brand products it's basically always genuine. If it's imported stuff the price will reflect it and you'll get better deals elsewhere.
The price difference between Chinese and English versions mostly has to do with the affordability and price expectations of the different markets. Simply and bluntly put , English buyers are getting ripped.
And BTW, I don't think the Chinese Taobao is intended to be used by overseas buyers. The sellers generally will not ship beyond Hong Kong and Taiwan. Plus a lot of them expect you to contact them to confirm shipping fee before payment, in Chinese!
Aliexpress.com is the official overseas facing version of Taobao. But again, you'll see vastly different pricing unfortunately.
If you are overseas don't use taobao or "englishtaobao" Use a taobao agent, much cheaper.
For me it works out so well and my agent is very trustable, only 7$ for the first 500g! and 4$ for the following 500g w/ EMS
And they pack so damn well, unlike DX!

So the ut61e has peak mode. Giving what difference to the min / max mode seen on other multi meters ?
I see the actual chip used supports both modes. So what is the diff ?
Sent from my HTC Desire
So the min/max sounds more useful than peak mode to me from that fluke text.
Thanks, Darryl

No actually you're not right nor not wrong.
It's good for capturing what min/max can't capture, it shows you the peak voltages in DC
But if it's in AC it shows you the peak voltage (non-rms)
Or very fast changing voltages
from reading the ES51922 datsheet the peak mode needs a 100us pulse to be able to read / capture.
the min/max works on many more functions than just voltage / current that the peak works on.
hmm, think i might get one of these meters and make a few mod's. ie this peak / min/max a backlight and the auto power off, all look very doa-ble from the UT61e schematic and the data sheet.
thanks all
:-)
It is true that when 61E continuity test leads to change the polarity?

You want to try that one again?

The red lead is negative and the black lead is positive in both Ohms and Continuity mode on the UT61E. The diode check mode is normal, however. I think that's what he's referring to.
It's a fact - it's written in the manual. -1.2V OC Voltage
Just received mine from Dinodirect in perfect shape.
Compared it to my 87V and I like the accuracy. The low capacitance measurement is great.
The probes tips needed some filing to remove the crappy coating that was preventing proper continuity detection.
Opened it up and all looked good, except that one of the fuses was half way out of the retaining clip. I pushed it back in.
Overall I am extremely pleased with this meter .
The amazing thing is that it actually has a LPF ...
Not that it's enabled on the UT61E.
It is ... It's enabled!
Like to verify T4P, is LPF refers to low pass filter like in fluke 87V usefull for variable frequency drive measurements??

I tend to reach for it first a lot too, since it does a round of things well and fast. Mine's original UNI-T branded battery lasted little though until the warning started flashing here and there. It was at 6.5V already. I hope it was not that good a battery and it isn't the data com being always on by default.

how long did you use it for? (Ah yes, i don't trust the batteries anyway) The Data's 24/7 on as long as you don't do a mod
3 months average to light use not daily.
Say a couple of tens of hours the most. Data being factory set permanently on is crap amateurism design by the way in that department if you agree.
Data transmission doesn't put much strain on the battery. Only uses 0.2 mA on the Uni-T 71D. Probably the same on the 61E.

Do you really have a choice? Read the chip's datasheet. Unless it was a new design to have a dual function switch to switch of RS232 which turns on APO
There isn't a extra button because they got laaaaazy! The hold button isn't used for a backlight because holding it down for 3secs enters delayed hold

1-2mA draw with data on, let's just say the stock battery is shit. Use a GP green battery then, those things go for 24hours with 8mA draw so you'll get about 100-200hours lifetime!
NOTE: Continuity draws 5-6mA

Don't know about that but that is worth a try. 0.2mA is alot when you are talking about PP3 batteries
It's a design choice, nobody advertised this meter as having long time logging.
I'd rather just get a
LT1610 and boost 2 AA (probably a bit of hard fit though) or 2 x AAA rechargable batteries up to 7-8v (high enough to not get low battery indicator)... even at 75-80% efficiency at 3-5 mA the meter uses, the AAA batteries will last more than a 9v battery.
Even non rechargeable AAA batteries would last longer than 9v batteries.
They just wanted same casing and buttons across the 61 gamut of models is my guess, simply volume economy. The crap stuff possibly goes to the management to be fair. Who designer would not take advantage of the back-light or would even bare to stare at the screen symbol with the S in it when the DMM is not doing data logging at the time, no matter if not taxing even. I spare the registered trademark phrase ''you can fly to the moon on 200uA'' to Dave of course.
They wanted to keep the look similar and not having to do a total redesign again. After all, they have one too many product ranges already and the UT-60 series was always more well built than the UT-70 so the UT61 and UT71 are the modern (2008) replacements
and... the UT60H (the top of the line) never had any backlight ...

7-8V is way beyond low batt indicator, a 18650 almost goes in which means it doesn't fit. A Double-A sits on the battery terminals How about a 10400/14500?(AAA/AA respectively) size

Suddenly price shooted in dino & the current price is $60.39,can't find any working $10off coupon ,there is one i,e,.DDVALENTINE but don't know it is still active or not.
