Very nice 👍
इस वीडिओ मे दी गयी जानकारी बहुत लाभदायक। धन्यवाद। इस मीटर की पीसीबी मे रेजिस्टैंस, वोल्टेज, करेंट आदि सेक्शन कौन से हैं और उनमे कौन कौन से रेजिसटैंस आदि पार्ट्स लगे हैं, उनकी वैल्यू क्या है, उनके खराब होने पर कौन कौन से फाल्ट आते हैं। कृपया इस पर एक वीडिओ बनाएं।
Very very very very very nice information sir 👌💙👍💛👍💚👍
Nice VIDEOS dami cha

Very informative vedio
Very good helpful video
Nice explane👌
Very good information
Hello sir....! Your video is really informative and in my case When I applied high voltage ac current...... it fluctuated and battery low sign was up....... but after that episode the multimeter reads 8 volt battery as 0.27 volts and all voltage readings are way too low...... please help......
Thanks in advance....!
Sir i have mastech 830L multimeter .... In continuity range it shows 449 value .... What's is the problem ??...
I have the same multimeter and it is having an issue related to resistance measurement. I was trying to check a mosfet but there were some sparks on the probe. On continuity mode I am getting a value of 377 and on other resistance measurements it is showing some random values. Will it be solved if I replace the PTC ? What is the specs of R8 ?
Plz advise on proskit meter..but your xplantion very good
Hello Sir, Thanks for your kind efforts in making this detailed video.
Sir I am looking your kind guidance to restore my same Digital Multimeater.
The Multimeater which is available with me, in that the R11, R12 and R13 resistors are burned out.
Please it is possible to inform me the value of such resistance.
I am eagerly waiting for your kind response.
Thank You.
Explain with full circuit diagram. You hide the circuit by hand not clear.
Sir mastech ke is model main valu apne aap reading hota hai kabhi kaam karta hai kabhi nahi, continuty beep sound prob hata lene ke baad bhi bajta rahta hai. Kaise thik hoga.

Please reply kijiye please sir🙏
Sir is multimeter me mene 9v ki jagah 3.7v ki 2 battery ko series me 7.4v banakar galti se ulta supply de di thi iski vajah se lm358 is short ho gayi thi to mene new replace kar di fir bhi on nahi ho raha he backlight on hoti he lekin display par kuchh bhi nahi aa raha he
Buzzer par prob lead par 3v aane chahiye vo bhi nahi aa rahe he please help kijiye
Main die bhi damage ho gya hoga

In case of my htc 830l multimeter, R29 and R30 are burned like , and my multimeter doesn't show any value, also the C2 capacitor is missing. how to check value of R8 resistor, & what is the actual value of it?
Mera bhi mastach ka multimeter hai main jab continuity check karta hoo to thodi beep aati hai aur display off ho jata hai pls mujhe problem batao . Maine battery bhi change ki phir bhi vahi fault aata hai.
Sir is ki sari faults ke bare me batao please
Nice video sir.. Mere pas yehi modal h but A. C And D. C Volt nahi dikha raha h please reply sir
Hi,
This is a very informative video. As a matter of fact, i have not found a better video on the topic in the web.
I have a question. I have the same multi-meter bought recently.
I was trying to measure current between the outer net and inner net of a mosquito net setting the meter at 200m amp. perhaps it was very low. it developed fault immediately, now when switched on to any selector position, the display backlight switches on only without showing any figure what so ever. Nothing works now. the fuse is ok.
During this period of lockdown, i am not being able to take it for repairing. please help.
Multimeter gone bro.
my same dmm is full dead...fuse is ok,pls suggest
Brother
I replaced my 9v battery with 3 lithium batteries in series it give me 11 volt
Now my multimeter not working
How can I fix it?
What you think is the damaged part?
I want your answered please
Thank you.
Low volt show karne ki kya karan hai ac, dc dono baki om amp theek show karta hai agar ho sakta hai to kya kar sakte hai mas 830L pl. reson jaroor batayen
Battery voltage bhi reason ho sakta hai
Bro, My 830L multimeter showing ac voltage is 560etc values instead of 230volts, dc 1.5v battery voltage is shows 3.2volts & in buzzer mode buzzer is not ringing....
Wat's the problem... Plz reply me if u know
Ramess S ji aap ki bty ka volt down ho gaya hai is se koi bhi ac, dc value high show karega bty change karne se problem solve ho jayega "tkanks"
Sir mastech 830L ke multimeter me mobile ki 2 battery ko series karke galti se reverse supply de di thi is vahah se lm358 ic short ho gayi thi to mene nayi ic replace kar di fir bhi on nahi ho raha he

Mere multi tech 850L continuity mode me 402 ohm bata raha hai { halp me}
Hi, i have a Hyelec MAS830L multimeter. I connected multimeter to 230V ac , keeping the selecter at 200 ohm resistance by mistake. A small spark came and now multimeter is showing wrong readings on resistance, like .003 @ 2M, 03.5 @ 200k, 3.52 @ 20k, .312 @ 2k, 50.6 @ 200 Ohms and 320 @ continuity without anything connected. Can I fix this or is it broken completely ?. Please reply. Thanks.
It is definitely dead
Sir, I have same circuit multimeter bun not showing any reading while testing the ac and dc voltage. Please suggest me, how to fix it.
