Paul, over the last couple years, I have watched many of your reviews mostly on multimeters. I really appreciate the time that you ( and other youtubers) that make videos on varies products. I think your channel is great for the electronic hobbyist.

YES!! Love the multimeter reviews

Good review - thanks!

I like the performance of that meter. Ty

Great review, dude! 😃 Thanks a lot!

Great review Paul by the way I thought your PCB key fobs are fantastic and if they are not all gone I will buy one Thanks

Thanks for reviewing our new multimeter, it's a reverse display, if you put the holder on and make a right degree, you can read the value clearly.

Oh ok I understand this, thank you

I was looking up a BSIDE ZT 100 review and your vid popped up , it's a close relative of it ....... The BSIDE does not have AUTO range and NCV , for that I am glad , I have a ANENG SZ02 smart meter and the voltages are in the auto range section , only mA's can be selected , OHM's and continuity can be selected ....... I don't care for the auto range myself .... Great video Mon Ami ....

lonlife cells short on current not firing up the whole back light?

Thank you very much Master

What is the allowed voltage when measuring current with this zotek? And what would happen if I measure current way above the allowed voltage?

Nice review. But it would awesome to see a comparison side by side between the displays of this one and that of the Aneng Q1. The display of this one seems more faded in comparison, though maybe I'm wrong.

What is the value or series of the PTC components? My multi meter is not accurate in measuring temperature. Is the PTC damaged?

Can you please do a review for voltcraft vc830? It's pretty similar to ut61d.

what I think sir,..what the best digital multimeter product to use

Paul what's it like to have Christmas day every day

Paul, who calibrates your Fluke for you?

is that better than AN8008? im looking to get one. please answer me

which one better between zoyi zt102a with zotek zt102 please help me for rekomendation

Can we reverse the lcd? Because, it appears annoying in outdoor or under the light. I need the background become white, and the number black

My multimeter zt102 reads max resistance 27k ohm only, how to repair it? , when open nothing is connected with probs it reads 27k

Cool, what's count now?

You are fall in love with multimeters

I don't believe I have seen anyone before this excited about (and in love with) multimeters :D

Thanks for review, interesting there is not eeproom or its other side.. my is Aneng AN113D clone .. order before week.

just got a Zotek 102. the capacitance reading is significantly high. tried different capacitors. is this defective? or is there a calibration i have to do?

I want this multimeter

That’s a nice little meter, but I’m not sure about the features they include with it.

Dissect and add a few more LED's if that's not the case.

The ut139S looks to have ( edit since don't have the zoltek to compare !!) a better inverted screen even with backlight off. Well another zotek / aneng meter for the addiction :D

The 600mA has a different reading than 10A. When testing in small Ampere.

Zotek pretty good meters yes they make anengs, richmeters, bside and zoyi etc but at least Zotek are OEM

I don't think my eyes like these negative displays. I recently got a Bside ZT-X which is basically a clone of the Aneng Q1. From the moment I turned it on the display looked slightly crooked (going from right to left the digits look progressively higher).

I have several lower quality DVMs that measure about 28 V AC when connected to any of my 12 V DC power supplies. My higher quality meters measure as they should, close to 0 V AC! What circuitry is missing from the lower quality meters, preventing them from getting the correct reading? I have seen You Tube videos of people measuring automobile batteries and getting similarly bad readings using Harbor Freight meters, and they are also scratching their heads!!!! Thanks for your videos!!!!

I think it is missing capacitor in series with the input which would otherwise block DC. In addtion, since it seems that most of the readings are over twice the DC input value, gives me the idea that software is giving a value in relationship to the inverse of it's function. In older analog meters, one method used was a bridge rectifer convert the AC to DC, but at a cost of a voltage drop due to the diodes. So if you double the DC input and take in the consideration of the diode drop ( 2*12+1.2=25.2 )which is approaching 28; however , that leaves a 2.8 volt mystery. Is it possible that your 12V DC power supplie is putting out closer to 13.4 volts( 2*13.4+1.2=28)? if not, as a guess, maybe the software must adjust for any additonal electronic component that is added in the voltage input section of the meter--a single cheap PTC for example. Anyways, it is a good question.

Thanks for that answer! I went back and looked at the last supply I checked and it was indeed a 13.8 V DC regulated supply! You are right on the money!!! I have posted this question several times on You Tube and your the only one to answer me back! Thanks again so much, mystery solved!

@@danedewaard8215 Your welcome; however, I was only making an educational guess based upon the fact that voltage (AC) is measured from the area under a curve--effective value which is 70.7 % of a sine wave. In more complex waves it is still the area on the curve. I think chips use calculus to solve the area under the curve, but DC doesn't have curve or frequency. The area is rectangle (L*W) where L is time and W is amplitude(voltage). Digital multimeters have a refresh rate that I think fools the software on the cheap meters. After all, they think a person will use their meter to test DC voltage with DC setting or AC voltage with AC settings. A good multimeter will be able to measure the AC riding on DC (termed: AC+DC), AC only and DC only depending on user's settings. AC only setting on meter most likely would have a capacitor in series with the actual input of the chip ( or internally ) which blocks DC, and DC only setting on meter would most likely have a capacitor in parallel to the circuit(or internally) which will shunt the AC to ground. Therefore, cheap meter manufactures use software to overcome the lack of properly design circuit--cutting cost. As an experiment, connect an external capacitor between the powersupply and the red test lead and connect the black lead to your negative post--check the DC on AC setting. The result should be zero or very little depending on the value of the capacitor--use the following simple formula: Xc=1/(6.28*C*F). If you want, let me know the results.

Mmmm, new meter smell!

did you use the same leads for the comparation?

TLDR: Is it better than Aneng 8008?

Aneng 8008 is able to measure lower currents than this one. Other than that they seem pretty similar to me.

I think both the auto function and the not so clear inverted LCD display are a gimmick or a joke on this multimeter. The inverted LCD with backlight is probably supposed to mimick an OLED display that is now in fashion with top of the line DMM's. I can't think of another reason to do that. So for that an Aneng8009 is imho a better choice. What this meter however as a plus has over the Aneng8009 (and older siblings) is that it has a REL button and a mA range. The Aneng8009 only has µA and then A, so there is a gap in its ranges. Of course this meter doesn't have a µA range and it's up to the useage for what is more important. Too bad that you didnt test the 10A range in higher amps (6-10A). The Aneng8009 is notoriously inaccurate in that range (20% misreading is no exception). Probably the shunt is too little, gets hot and is of inferior heatstability material.

they prob dissabled the other led's because the ozzy foundout these reversed lcd's draw allot of milliamps lol

Just an intellectual curiosity, Is that all you do ,, testing tools or you actually do some electronics projects that makes you earning? Or am I right in getting this sense that like most of the skills, this is also a dying skill and only good to make money off youtube? Just so that I don't waste my time on learning something and realising later, its no good as there are no scope to make money... I mean I surely came to watch the review of this multimeter but then it struck me the above question, which I had to ask. I hope you understand where I am coming from.

You get a thumbs up, the crappy meter does not.

Cool...Great for Nerds who live in the Dark...lol
