TA-0351: UNI-T UT181A Functions & Software - Hands-On 

Thanks you for you sharing, yes def agree

Yes :)

Yes, I understand that it's not IP67, but I still wanted to poke fun at a multimeter for having an IP rating.

LOL... yes very usefull :)

@@EricYTP ip rating is very useful if using the meter on ohms outside when the weather is wet .

So much of their gear is junk, but they did better with the UT181A.

Yes they did a good job on this one.

LOL

Thank you!

Thanks, you guys are luckey, we pay 414,- on amazone in Euros, so that like 450 in US. Looks like to put some real attention to this meter making a nice product.

Thanks John, not a minor point, great you mention this, i am not even aware of that standard... great i will look into that.

@@TonyAlbus Siemens ( the units not the company) were previously known as mhos.

@@ricksharpe6895 Good info Thanks!

Thanks Marnix, yes correct, more testing needs to be done. interesting meter for sure

Regarding battery life, the Uni-T also chews thru the battery, possibly that display uses a fair bit of power. And remember its a rechargeable battery, so if it goes flat you will need to recharge before you can use it again, the fluke you can replace the AA batteries (I use eneloops to avoid batt leakage). I havent directly compared my 181A with the 289 for battery life, but but I think the 181A has a slightly shorter run time. Though my main go to meter is a Bryman 869s or 786 usually, so I dont often use the 289 or 181A.

@@nikmilosevic1696 Thanks for that compare, yes the brymen is very good, i like mine too

Yes agree, they make some nice stuff

Thanks Grer

Thanks! i will have a look at that one.

Hi Guido, yes good points, the data can be exported to csv... about the calibration we need to find out still.

Thank you!, yes very nice meter

Thank you! yes i do. if i not had de fluke 287 i would buy it myself. read in the comments were people find small hick-ups i did not found in my test. you so make i good decision. but i would buy it.

Thank you Tony.

Thanks, that is a good question, the thing is, i do not have it anymore, it was a loaner.. and i do not remember.

Hi Mike, that is where a multimeters and Oscilloscope are different. the multimeter is more for slower but longer logging, while you need something fast. If you have some money to spend have a look at the Fluke 123 or 124. if you have a budget. Owon made a nice one and Zotek is nice but for automotive maybe to fragile. i have at least 2 videos about the Owon DMM/Oscilloscope combi. HDS272 or the now newer now HDS2102

Thank you!

Hi John, yes correct, not all multimeters can handle the emulated resistance of the LB02

Thanks!

Hi, i dont have the meter anymore.

@@TonyAlbus I see. After reading the specification I guess it will be 32.768 kHz. 1 Hz resolution should be enough to adjust quartz clock generator. Thanks anyway. 🙂I need to correct my expectations. 1 Hz resolution is not sufficient to adjust quartz clocks. 1.13 Hz frequency change results in 3,0 seconds/day accuracy change for clocks with 32768 Hz generator.

Thanks for sharing!

Unsave is always dangerous. if you are planing to use 600+ Volts, maybe have a Fluke If you use it electronics the UNI-T is a great meter.

Hi John, yes proven by some Fluke items i have in the Fluke Friday series on my channel, that still run even after 50, 60 years!!

Thank you!

it does not have 4 wire, so i would not get too exceted about it for lower then 1 Ohm.

how could it not measure less that 1 ohm ?

Thank you, for pointing that out, the trend needs to be tested longer...

Sadly it's true. But better than CEM DT-9979, which does not have zoom at all.

@@TheGrantourismo Indeed, I also have the DT9979. The good thing with 9979 is that you can calibrate very easy.

Hi, this video was 1 year ago, i do not remember by heart, but if i did not mention it or you do not find it in the comments, i guess the usual 5 hours at least. but it could be longer.

Hi, i dont remember, it was a borrow, i would think just a few hours, if it was crazy long i would have remembered

@@TonyAlbus Thank you Tony I have the same problem it takes a long time to charge. Not using it anymore?

@@stankostankovic9008 It was not mine, it needed to go back to owner. but i liked it the short time i used it to be honest

This meter stops recording when the battery is empty.... like any other

Hi @@TonyAlbus, thank you for a great channel with great content! I understand that it turns off when the battery is empty... 🙂What I meant was that when I do measurements over long times I prefer to have the power supply connected so that the battery discharge-time does not limit the length of my measurement. And if I understood it right the battery-charger of this device is using the input terminals so this rules out this device for very long time measurements.

Yes you are correct about the charger, i did understand your point, but i do not have one handheld in mind that can use an adapter to charge if i think of brymen or fluke... maybe the fluke 867, but not sure about the recording and memory. most other normaly priced multimeters just have non-rechargeable batteries. i saw in the comments that one viewer used it for 2 days before the battery died. 2 days is not bad. and thanks for the nice comment!

@@TonyAlbus Ah, ok. I was comparing with the Fluke 199C that I use for logging data sometimes. Ok, yes, 2 days is enough for most measurements. I suppose what I need is a type of data-logging device instead of multimeter. Thank you and have a nice afternoon. /Tomas

@@tomasbergh Thanks, same!

Hi, sorry i do not remember and it was a loan, so i can not test it for you.

Ah dang, no problem. Thanks anyway.

Not sure, also i dont have it anymore... if i remember correct 7 hours of logging.. but not sure

@@TonyAlbus thanks. That's a bit too short, I was hoping for 24 hours of logging...

​@@TheNefastor7 hours with the little original battery pack is too short??? 😂😂 dude, get an external powerbank and limit will be your fantasy 😂😅

@@GioJonnhyK it's a logging meter. It has to have endurance or it's pointless. I'm looking to measure voltages and currents over several days. And you can't use that thing while it's charging.

@@TheNefastor nope. IT'S A MULTIMETER with the function of logging. Energy density in batteries is NOT a UNI-T decision but PHYSICS in this Universe.

Yes the UT181Ahas more digits nicer graphical screen, i like it. if i not have the fluke 289 i would have kept it for myself.

@@TonyAlbus From all the multimeters I've been watching for almost 1 month, I like these: Gossen Metrawatt M274S, Fluke 289, UT 181A, and Brymen 869s. All the others a saw and collected information - do not like

@@siderov777 The bryman is great, lot of digits, but it is a bit big, price wise that is a great choice

For the price difference you can prob buy a golden bag :)

Thanks for your feedback

@@TonyAlbus you do a fantastic job with these reviews it is helping me to decide which machine to get. keep up the good work

@@bifftannen3167 Thanks Biff!

Hi, depends also on the digits you wand. If you want something good look for Agilent 34401A secondhand en ebay, if you want new. Siglent has nice SDM3000 Series. 4.5 5.5 and 6.5 Multimetrs..

@@TonyAlbus Thank you for your suggestion, I'll go with Siglent, 5.5

Yes agree more for electronics than HVAC
