Multimeter and oscilloscope car diagnosis - KKM828 review
Vložit
- čas přidán 1. 06. 2024
- Checking out what can be diagnosed in car using a multimeter, and reviewing at the same time KKmoon KKM828 graphical #multimeter with oscilloscope. Starting with simple measurements like car battery voltage, voltage drop at crank, voltage peak with engine running, then checking glow plug resistance, watching up close N75 vacuum valve power signal and footwell LED PWM control signal, checking current consumption by the 12V power outlet, and looking for ground connection for 3rd party accessories hardwiring.
👍 In my opinion it's a great device for testing and diagnostic various things around a #car. I've used it when I was retrofitting rear warning lights in VW Golf MK7 and it was a huge help. I'm not a professional mechanic, diagnostician, electrician, or electronic, but I find KM828 extremely useful. It will find a place in my toolbox.
⬆️ Pros
#Oscilloscope function and graphical data display
Small form factor (for something with oscilloscope)
Readout database with 100 inputs memory
Auto range for measurements
Automatic sleep function to preserve battery
Safety reminder (sound + graphical) when working on high voltage
⬇️ Cons
Would prefer a device with USB battery charing option rather than 3xAA battery setup.

Great review. For a non professional electrician, you handled the device amazingly. Thanks so much.
Thanks!
Great video. I liked how it can display, at the same time, the high voltage and low voltage when you started the car. Easy test for battery condition. That alone is a selling point for me.
Thanks for posting such an informative video.

8:59 1.7 ohm comes from maybe bad connection not the probe resistance itself cause there's no resistance in probes. Instrument is so precise it shows everything. Great instrument.
Огромное спасибо за ваш ролик, все наглядно, просто и понятно!
Great thorough review. Thanks for your input.
Just got one thanks for the information great video keep up the good work
Very good review. Showed lots of great examples how to use it effectively.
✌️
Thank you You really are very nice to make this video for everyone to see.. Good man! Hey do you know if the LM2020 is the same as yours??
Thanks 👍
Огненный обзор. Автор, спасибо, это реально очень круто.
thank you for the superb video demonstration, it's a shame no demonstration on the can bus and surprised at the size of the multimeter
Thanks. Useful review 👍
✌️
That was a nice review, thanks
Glad you liked it.
For charging - There is so much room in the back - it can be easily replaced with either lipo (lipo battery @full is 4.2 so it's just a bit lower than 4.5 or 4.8v of alkaline) or just in parallel of the batteries (it will need recahergeable AA batteries also)
great content, thank you so much.
Welcome!
Nice review!
Thank you!
Good device and cheap , nice one
Do you have one? Would love if you shared your thoughts!
@@mrfixpl
No but its I definite buy , as quick and easy to on automotive systems , thanks
Let me know how you like it after few days! 👍
Super, thank you
Très bonne video. Merci
Good review. You can't look at CANBUS with this ... ?
👍👍👍...наглядно, понятно!!!
Super!
✌️
Cool, was just looking for something like this
Yeah, I was looking for something that will help me check PWM signals controlling LEDs and this is perfect for the job.
The oscilloscope work for laptop repair?
Question: what is the maximum time I can record a scoop measurement and save it?
Hola el voltios también puede leer los parámetros del sensor map de cuatro líneas gracias
Instead of using the lead, will this work w/ a low current AC clamp???
can it show canbus signal on the scope too ?
Great explain... what's price brother
Can this tool test CAN -BUS circuits just asking I will wait on your response thank you
Well, it will not decode CAN-BUS communication, that's for sure.
There's also one input channel in the device, when CAN-BUS is 2 lines with differential signal.
But I will check what will happen if I connect it to CAN-BUS network, just to see what we can get on the display.
1:43 'COM' stands for 'Common' ;-)
This just proves how unprofessional my tutorials and reviews are 😅
@@mrfixpl hehe he. Each review has a different angle on the matter. It was appreciates to see how you would use it. Arent things I normally do. The wording is not the relevant, but the results.
Is the KKmoon a copy of the Liumy?
im buying a hantek and this one too
Let me know how you like them!
Can you move the zero line of the scope ?
No.
That's a MUST-TOOL meter, its a copy of the Must-TOOL, Lumy & others. But STILL GOOD METERS.. DON'T LET THIS COMMENT PUT YOU OFF BUYING IT. THEY ARE WORTH THE PRICE!! WHICH BY THE WAY IS CHEAP FOR WHAT YOU GET. PUT IT THIS WAY YOU WON'T BE DISAPPOINTED NO MATTER WHICH BRAND YOU BUY..😊
have u used these to test out ckp or cmp sensor waveforms ?
@@JayDee-ve6ml I have used this particular one in the video for O2 sensors signal.
Damn!!! $29 at Walmart?
Let me know how you like it, if you get one.
Me equivoque. El voltimetro.
lin-bus test , kann man damit messen
asciloscope lin bus messen was mus man einstellen
左下に日本語の訳分が表示されているが、小さ過ぎて読めない。
useless... you need min 2 inputs to compare timing between sensors.
True, you can not do everything with this tool.
You get what you pay for....
