New ANENG Q1 9999 Counts ?

[joeqsmith]

Now THAT is funny!!!!

You don't think it will meet its CAT rating? 

I notice they've gone down a CAT level, it's now CAT II/III instead of CAT III/IV.

  You were quicker.

[joeqsmith]

Put a few drops of pump gasoline on that lens and let me know what happens.   It it just another pretty meter?

Maybe they'll have the last laugh. 

Actually, I know they will. Whatever's inside it, no matter how power hungry the screen is, I'm sure they're going to sell millions with a design like that. I'm almost tempted to be the first to have one at Arduino club.

[GreyWoolfe]

And now that the Q1 is out, the 8009, that I paid $19.99 for is now $34.99.  A whole dollar more than the Q1.  I guess they want you to buy the Q1 now.  I am surprised that they didn't do the same pricing on the 8008.

[Mr. Scram]

I want to see the quality of LCD. This is quite a photoshop job they did there. Other Aneng meters have unusable viewing angles.

What makes you say that? The Aneng meters are far from perfect, but the viewing angles and contrast are on par or better with meters from the big boys.

The display sure doe look nice, but not if it's at massive battery life destruction.

Not sure about the pushy buttons, but then again, is a preference for dial just really being traditionalist for no reason.

I live in hope that they use proper sized and obtainable fuses, but I won't hold my breath.

It's bigger than the AN8008 et. al., they already use ordinary size fuses in their bigger meters (eg. the 860B+).

[EEVblog]

I've ordered one, we'll see what's it like.
I don't particularly like the inverse screen, might be better in the flesh.

[Fungus]

The display sure doe look nice, but not if it's at massive battery life destruction.

Judging by the unevenness of the backlight in the first video, it looks like they're using two LEDs, one on either side of the screen.


If so, current consumption will be about 40mA. With a 2000mA battery that's 50 hours, not good but not awful. For most users of this class of meter it's going to last for many months.

It's nothing like the soul-destroying power consumption of those Agilent OLED meters (which also can't be used while they recharge  ).

[daveshah]

Yes, at least it uses AA batteries (confirmed here: https://www.aliexpress.com/item/OUTEST-ZT-X-digital-multimeter-ac-dc-Ammeter-voltmeter-Ohm-Portable-meter-9999-counts-Backlight-true/32880281145.html), so it shouldn't be too bad and you can stick nice high capacity ones in if you want.

I think that's assuming no other issues. My AN870 eats batteries whether it is off or on and to use it I typically have to replace them. It's in my "Maybe I should just throw it out?" pile. Two LED's is a good guess, it's what they've been doing this far.

[Fungus]

Also shown in the second video (he installs them on camera).

You can clearly see there's two LEDs in the publicity shot from that page:


(You'd think they'd have photoshopped that image...  )

The display probably looks good in a dim basement, maybe not so much in a brightly lit office. 

Edit: It looks distinctly "Meh" in this other image from the same page:

I wonder how you estimate the current consumption, a meter with one led can easily be below 10mA.

[HKJ]

You obvious have a faulty meter or use faulty batteries. The meter do not use current when the range switch is on off and uses less than 2mA in on (Backlight adds about 7mA).

[Fungus]

Sure, but that's for reading in the dark.

This looks like the display depends on the LEDs for contrast so I'd assume they want them to be as bright as possible. They certainly look bright in the second video.

(besides, there's nothing wrong with "worst case" analysis)

[Mr. Scram]

I see it has a bar graph. That could actually be interesting.

[stj]

the real questions,
what chip does it use,
and does the led circuit use a boost convertor or a resistor?
because the older meters light a lot dimmer on rechargeable batteries.

[Fungus]

and does the led circuit use a boost convertor or a resistor?

I'm guessing it has to be a boost converter.

The fancy screen depends on those white LEDs and battery life will be awful if it can't keep going down to 2V.

I also spotted this meter as "Richmeter RM409B"

https://fr.aliexpress.com/store/product/RM409B-True-RMS-Digital-Multimeter-Button-9999-Counts-With-Analog-Bar-Graph-AC-DC-Voltage-Ammeter/909123_32878214801.html?spm=2114.12010612.0.0.792b41f1t0Su4P

Here another view of this meter:
https://cloud.video.taobao.com/play/u/17300505178/p/1/e/6/t/10301/50143362094.mp4

Display looks good, but I won't buy a DMM which sucks the batteries empty faster than a vampire could.
I'm kind of intrigued by the UI from rotary switch to push buttons.
I never liked the big rotary switches on DMM's.
But I also don't like to push a button a gazillion times to select between funktions.
My ideal UI would be a push button for each funktion, like a lot of the benchtop DMM's do.

I am curious about an in depth review of this thing though.
I really would like to know which chip is in it and how they do the switching between the different functions.

[Fungus]

But I also don't like to push a button a gazillion times to select between funktions.

You already need to push buttons to select functions on many multimeters, eg. a lot of them put Ohms, continuity and diode on the same position on the dial and you have press a button to select the one you want.

Overall I don't think this meter is more button pushes than before. It looks like it actually might be less overall.

(and how many button pushes equals one use of the dial? Dialing is often a two-handed operation)

The batteries are fine considering every single thing I put them in works normally. As to a bad meter, that's more or less the point. I bought 2. One was pretty much DOA and the second eats batteries. Considering the one I sent back apparently disappeared in the mail on its way and I still like to see what they manage but I'll probably stick to real quality meters.

I'm guessing it has to be a boost converter.

The fancy screen depends on those white LEDs and battery life will be awful if it can't keep going down to 2V.

When you see a cheap multimeter with NCV function, almost you can assume it is based on Taiwan Hycon chipset, with bar-graph function, most likely it is Hycon two chipset DMM solution.

I'd put money on it being a DTM0660L or variant there of (eg DM1106EN)

My experience buying from drop shipper (bangood included) is no good.  My guess is they are selling QC failed items.
ZT-303 is another interesting meter.

DTM0660L is Hycon HY12P66 chipset

take a look HYELEC MS8236 DMM (similar to Q1), it is using DTA0660L (HY12P6x series) + HY11P14
