*A lot of you guys are interested why the multimeter worked when I had the black lead incorrectly connected to the Amps socket instead of Common socket. This is so interesting I decided to make a short video about this and it will be published tomorrow*
I think hi current socket has a very low resistor (shunt) and instrument measure voltage drop over this resistor. So, no much difference from current socket and common socket due to low resistance over the shunt. Your videos are very interesting and education and keep going! I join your chanell today but more than a week i saw ...30? of them and all are good. Regards, Iztok from Slovenija
That mount on the bottom, while simple, is a great addition! You could mount it on a tripod as you say, or one of those articulating arms. Then you could easily swing it around and point it at a spot on a board to watch a component over time without having to stand there holding it! I have one of the MT15S's (next model up) on its way to me as we type.
It should and yet it works :) Interesting. I didn't notice my mistake because it worked as I expected. My guess is the A connector connects to the Common via the fuse and shunt which itself is very low resistance, must check this out today, think I accidentally discovered something there. I wonder if this applies to all multimeters, more or less 😅
@@LearnElectronicsRepair we demand a redo of this review with the leads in the right positions... as the shunt could confuse the diode test and will add a little resistance with resistor ohms testing
Most meters will beep if the lead is in current socket but you're not on current setting. You should make a suggestion to manufacturer to update the software to fix that, then do the firmware update and re-test / re-review.

@@pault6533 Joined leads is not a thing. I've been using a Fluke 12 since 2005 and it has separate leads as do almost all dmm's. If a dmm uses joined leads I would not buy it. It's cheaper to buy the $2 chinese dmm leads and use them for 6 months then toss and buy new ones. Some years ago I bought a pack of 5 sets and I still have 2 sets here. Before that I made the mistake of buying a set of Fluke leads for $50 and they only lasted 1 year then broke. I'll never buy genuine leads again, plus I really like the needle pointed leads which is very suited to the specific work I do.
Well actually sticking the lead into Common instead of Amps, although technically correct, would make absolutely no difference to the review. I'll explain and prove this in tomorrow's video. Already scheduled to publish 08:15 UK time
6:47 Notice the sensor resolution 240x240 is "ISR" which I understand means it is UPSCALED. IMSAI guy checked with the supplier and the actual pixel resolution of the sensor is 96x96. So it seems when they went from 13s to 14s, they changed the ISR upscale, but did not significantly improve the sensor other than 20 to 24 Hz refresh rate? @LearnElectronicsRepair can you check with the manufacturer if they increased the PHYSICAL pixel resolution on the 15s, and also compare the image quality of the three units once it has been delivered? I don't care about the multimeter functions of the 14s, because it seems they only changed from a touch screen to buttons and added amps. I'm much more interested in the multimeter functions in the upcoming 15s, which appears to be dramatically better and with higher counts. The 15s display also has more pixels, and the spec on the imaging sensor is higher (or it's another level of ISR) and at 25 Hz. 5:20 It appears the macro lens covers the flashlight LED when not in use. I wonder how that changes the flashlight output?
Yeah I saw the IMSAI guy video regards the IR resolution. Also Interestingly regards the ET15S that IMSAI guy said Tooltop were not sending out promotional samples, I also asked for one and they said YES. In fact it's already here and in the next few days I'm going to publish as direct comparison ET13S vs ET14S vs ET15S video showing all three together. Watch this space 😉
I would have loved a side by side comparison with the ET13S, concerning performance of the IR cameras. Headrd already somehwere that it has a real IR resolution of 32 by 32, the rest is interpolated.
Hey Rich, Am I missing something? Every test you did, you had the black lead in the Amps socket? Sure, it still worked, but I'm surprised there's no auto detect buzzer to deter one from accidentally leaving the leads plugged in wrong and possibly shorting something out, or blowing the meter fuse. I wonder if that's why they included a new fuse🤣 I'd also be interested to know if it warns you if you are in Amps mode but have the leads connected for voltage, ohms etc, as well as if test accuracy is any better with the leads connected correctly for the selected mode?👍
The plastic jack for the A port is black, should be red - and so should the main input. I believe the manufacturer shares the responsibility for the user error. The thin yellow marking around the hole isn't enough.
And it made no difference to the operation of the multimeter... this fact and the reason why is so interesting I just recorded a video explaining it. It's gonna be published tomorrow
The only difference between amps and ground is a high value, low resistance fuse. You can get away with using this with the black wire in A instead of COM, but not with the black wire in COM and red wire in A. 💥
for the resistor and diode tests... timestamp 10:00 yo got the black lead on the current buss not the com buss!!!! if you put the leads on the right busses it may not get confused !!!!.... we demand a redo of this review !!!!
Yes but no but... putting the black lead in the A socket (while incorrect) makes no difference to putting it in the C socket in this instance. In fact this is so interesting I made a video explaining it. You can watch it tomorrow 😉
Hi Richard, Does it pass Mr bleep test when connected correctly? (Black to com), is that a safety issue that it works when connected incorrectly? Thanks in advance for your reply.
Interesting (didn't spot a link, but found it, £117 is very reasonable). Does the Ohms range have a zero / CAL as it seemed to show 1.3 Ohms with the probes linked (9:26)? Decided not to go with the gag about your hot wife (12:24).

I totally agree, while it is such a simple thing the standard tripod mount on the bottom is an excellent addition for all the reasons you mention 🙂
I like the "cat ears"
Batman's multimeter.🦇
Seems fine! I just ordered one for myself
Richard, you have the probe in the wrong port
Yeah and it worked just fine... I'll explain why and how tomorrow
Should the black probe not be moved from A to Common? when testing diodes?
It should and yet it works :) Interesting. I didn't notice my mistake because it worked as I expected.

They may also change the spacing from the COM to the Amps so that leads with standardized spacing will not fit.

also you should test the curent accuracy as you have not done that.... so for sure a review redo
I did say in the video that I would demonstrate any of the other multimeter functions viewers wanted to see on the next livestream
