Thanks very much for your video
I had just damaged my DT830B by setting DCV and connecting to AC voltage.
I was going to throw it away when I disassembled and saw these tiny SMD components.
How to find the faulty one???
The I saw your video orienting to check the resistor and identifying the faulty one!!
I did the same and found a similar sign on one of the resistors, when checked it was faulty!
It was a 900 ohms.
I then removed it and replaced it with a 102 (very close) also SMD
The multimeter is back in business!
(It measures AC 10% higher though)
Thanks a lot my friend
Best regards
Bro which resistor u changed.. Can u help me.. My multimeter also ahows -1 problem..
@@AmanKhan-ec6lg Most certainly, my friend
I have looked for the resistor with signs of damage according to the orientation in this Vídeo. The resistor I found to be defective was the 9000 (900 ohms) I replaced it with another one that was available of 1000 ohms.
The result was good, because it started again to measure voltage, although with an increase of 10% in the read value. So I bought the right resistor (900 ohms) and replaced and now it is ok.
U can try to identify with a magnifier or u can measure with some other multimeter.
Best luck for u

i have some resistor show the lower value than the actual number showing on SMD
when i remove the smd n measure it the result is normal then i put back on the resistor
my multitester going erratically
no short circuit just after i change the new buzzer to the louder one then the problem happen
Useful tips - thanks. It would be more attractive if audio is incorporated in the video.
very helpful. Thank you
Patience is your victory very useful thank you bro
My brother "Anees Ahmed" thank for your support ,,, I make 93 videos ,,,, Hope that you may like also,,,,,
Many many thanks my brother & have a nice day.
I like this guy pure,silence but sure :-)
Excuse me sir do you have the schematic for the exact same model? I'm trying to figure out the value of each smd capacitor especially the one that is located near the top left corner next to the big green mylar capacitor.
_BRAVO. SUPER._
Good, BUT I cannot understand how you converted SMD code into Ohm? What I know it is 1200 M Ohm because:
128, a Three Digit Code, follows:
= 12 x (10 x 8) OR 12E8
= 1200000000 Ohm
= 1200000K Ohm
= 1200M Ohm OR 1200 Meg Ohm
Please correct me if I am wrong
Neither of your tested resistors gave accurate readings, the big 470 Ohm resistor you checked gave > 580 Ohm, why is that?
It's 1.2Gohm. u r right
You can help repair ladder diodes no burn but no working, no buzz. Thank you.
U R The Best
Me parece bien tu trabajo
My brother " Huevo peiscas " thank you again comment me.
My brother please wright your problem in "English Language".
Thank you my brother & Have a nice day.
Your video is very interesting bro. . My multimeter DT-830D. By mistake I checked AC current when the red probe was inserted to 10A-DC. Now the multimeter display is there, but it is not reading AC or DC voltage or the continuity. Checked for any burnt SMD or other part, but could not find any damaged component. Can you pls advise me how to repair this multimeter Thank you.
Good luck sir
Hi Nihar.. I watched all ur videos, Nice work. I have two multimeter One is from Orpat and other is from Mastech both have same problem. Showing auto reading even if not used and always shows 1 in DC voltage. Sometimes shows reading. Please help
My brother "Zubair Shaikh" first thing thank you for comment me.
Main cause of this problem is due to weak smd resistor or burn smd resistor.My brother can you give all number printed number on smd resistor ,,like R16=103 etc ,, so I give you all resistor with appropriate color code.
Thank you my brother & have a nice day.
@@kcdash9638 hi, i have same issue with my dt830d multimeter shows auto reading without probe, in buzzer range non stop buzzing. Help me to fix this. Thanks in advance
Nice video......keep it up........I have MECO 27 auto multi meter in it 230 AC voltage is showing 0 and some time it shows 70 volt not shows exact voltage so what's the issue please suggest........!!! What to do if this issue is inthis yellow Meter.....?????
My brother "Nicks Torc" first thing thank you for comment me .
My brother this type of clamp meter is used to detect the induction current flows in wire so don't worry about smd burned .
Only you can use cotton & little amount of petrol and then just smoothly wipe the whole ckt and also clean the rotor ckt connection then fit tightly & correctly.
In my thought this type of problems persist when the rotor contact is loose through the ckt.
Thank you my brother & have a nice day.
Sir,
I have one DMM (HAOYUE DT830D).
Problems are as follows:
(1) Installed new battery
9 volts, the broblem is that inspite of fulled battery, in mode there is no display only dot is displayed ( Like (.) and on bugger/continue mode only (-1) minus one is displayed and slowly it disappeared. will you kindly give solution to what shall i check on PCB of DMM and why such problems are arised whether due to the fixed I.C.(Black) any bad components like Registors/diat/capacitors/bugger attachments.
Pl slove the prblems Sir.Thanks.
Display problem in my multimeter plz 1 video in display
अगर साथ में बोल भी देते तो और better होता...👌
আমি DT830D use করছি আমার ডিজিটাল মিটার মিলিআম্পিয়ার সেকশন নিলে অটোমেটিক রিডিং বাড়তে ba কমতে থাকে বাকি সব ঠিক আছে
কি সমস্যা হতে পারে একটু বলবেন !

Sir Voltage Galat Bta Raha Hai Koi Idea???
Mene smd chenj kar diya uske bad bi ridding shi nahi dikha rha h uska kya karan h btaye Bhaiya
My brother " Chetan Sharma " thank you again comment me.
If bad reading shows to aap apna R2 we Lekar R7 tak check karna hoga agar koi jala hua hai ya dry solder hua hai
R2 jaise ki ye sirf serial number hai aasli number smd me upar likha hua hai to aap jise nikale uske upar Jo number likha hua hai ise mujhe R2 se lekar R8 tak jitne hain uske upar Jo number likha hua hai mujhe comment karna jaise ki
R2=499
R3=559
Ise tarah we mujhe bheejo ....uske bad mein aap ko resistor color code ke sath bhejoonga....Thank you & have a nice day....
actually what is the problem in multimeter
My brother first thing thank you for comment me.
The problem is bad reading in Ohms reading & kilo resistor problem in multimeter.
Thank you my brother & have a nice day.
Multimeter ka smd kharab ho jaye to kya karna chahi ye
My brother "Chetan Sharma " first thing thank you for comment me.
Aagar aap ka SMD jal jaye to iske upar jo chota sa number hai isse aap convert kar ke aap big resistor with appropriate color code ke saath Laga sakte hain.
Thank you my brother & have a nice day.

Please see the register numbers if anyone is wrong place change it. Please also give me code colour numbers. The problem is wrong readings are shown in LCD, A/C,D/C .I am sorry to trouble you, as I am senior citizen and I am very interesting in electronic repairs.
Other request is that I have one other DMM DT830D UNITY model. In problem is full charged battery is connected but there is no display on LCD screen pl give your valuable guidance. Once again lot thanks.
I am a Newley appointed electronic engineering candidate.
This little initiative of defective meter repair accomplished by me.
Respected senior citizen sir,,,,,
"Sham phadnis" the list of resistor with color code as per your concern.
R1&R2=514 = 550K Green Green yellow gold.
R3=1302=Brown Orange Orange Gold.
R4=3009=300G Ohms no need to replace it its thoo high resistor.
R5=224=220k Red Red Yellow Gold.
R6=1000=100 Ohms Brown Black Brown Gold.
R7=224=220k Red Red Yellow Gold.
R8=1001=1k Brow Black Red Gold.
R9=514=510k Green Brown Yellow Gold.
R10=1000=100 Ohms Brown Black Brown Gold.
R11=105=Brown Black Green Gold.
R12=2002=20k Red Black Orange Gold.
R13=1000=100 Ohms Brown Black Brown Gold.
R14=1002=10k Brown Bkack Orange Gold.
R15=132=1.3k Brown Orange Red Gold.
R16=1006=100M Ohms No need to Replace.
R17=9002=90k White Black Orange Gold.
R18=9R00=9 Ohms use 10 Ohms Brown Black Black Gold.
R19=3523=352k use 350k Orange Green Yellow Gold.
R20=R990=990M Ohms.no need to replace high value .
R21=5483=548k use 550k Green Green Yellow Gold.
R22=224=220k Red Red Yellow Gold.
R23=224=220k Red Red Yellow Gold.
RY1-64R9=64k Blue yellow Orange Gold.
Meter repair is time taken job just do it as a practical ,,,,,, My point of view if the display is work the meter is alwright.
Try to find rare resistors/ohms in your old Tv & Radio Ckt.
