great video

thanks for the new video, everything is well focused now! Can you tell me the capacity of the accumulator [mah] ?

Sorry, I do not know, but these batteries are usually from 2700 to 5000mAh. After you charge the battery, it last for a long time. Glad you like this version of my video better than the others, where focus was a problem. Have a great day!

Hi Tony, can you please check if your device can run a self-test? Normally these testers enter self-test / calibration if you shorten all 3 pins and start measurment. Unfortunately my device is not entering this self-test mode - it measures just the resistance of the cable as est 0.12 Ohm

I have tested the tester with 3-pin-shorted-out, provided with the kit, but it doesn't do the self-test either. In the SETUP you can turn AUTO-OFF or turn TEST mode at the startup - that's about it. I think it does the calibration internally during the bootup-sequence, so no need to calibrate.

@@tonysfun thank you for checking it for me. In my opinion the TEST mode at the startup just enter component test automatically instead of bringing menu on scree - no calibration :(

Появилась ли новая прошивка? Firmware????

Sorry, but I can't read your question. If you are asking how to update the firmware? I do not know how to do that.

People asking where and how much is this tester, so here is the info: www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=Multi-Function+Tester+MTT-V1&_sacat=0

Thank you. I have already ordered. Now I'm suffering. I don't know what processor is on the board. I'm looking for an ATmega 644. It has 64K cache memory. It is possible for a tester to change programs to write new ones. I ask you to open your tester and look at the big 44 legs chip. What is its name? Please. Sorry for the inconvenience.

I bought this. This meter MTT-V1 detects a 3.3V Zener diode as two diodes. It detects an inductor but overestimates the value 2-3 times. This is not an ATMega-based tester,

@@maf2 Well, to be honest, I didn't care much about the processor as long as it works. But I do understand that in your case that is an a important info! I'm not that good in electronics, despite having lots of equipment and options in many hobbies. But if you find what CPU is there and how to program it, I'll give it a chance. Thanks!

@@tonysfun The Zener diode correction shows accurately, but you need to plug it into the last two slots. However, the inductors are measuring incorrectly. For 1 mH, it shows 2845 uH

disassembled this tester. The microcontroller is a Chinese clone of Atmega 328 / LGT8F328.ESR, it shows sometimes no. And that’s not correct. Schottky diodes are identified as a resistor. Maybe the firmware is normal, but the controller is crap. It needs to be replaced with an Atmega 328

I'm using it sometimes and it works well. I compared it to several other LCR testers and found it to be accurate. Did you remove the original Atmega chip and installed the real Amega chip? D you have a video where you did this? Thanks for your comment.

@@tonysfun I only found your video on KZread. There are no firmware or circuit diagrams for this tester. I haven’t changed the controller yet. I’m just examining the board Maybe you have an original controller on the board, that’s why it works normally. I don’t have an inscription on the controller, it’s worn out. I'll try to change the controller, maybe I can fix it so it works correctly My translation may not be very good. I’m just from Ukraine

I understand your English just fine. I hope your country end the war and Rusha leaves! I do not know if my tester has the original or a copy board, but in China they copy everything including from other China manufactures and just rename it.... I'm not gonna disassemble my tester to find out what board is in mine. What is wrong with your tester?
