🔧 Multimeter – Mobile Technician Ka Sabse Wafadar Tool!
Jab koi phone repair karna hota hai aur samajh nahi aata fault kahan hai, to ek tool technician ka asli hero banta hai – Multimeter!
Chahe aap beginner hain ya ek skilled repair expert, multimeter ka sahi aur complete use aapko professional banata hai.
Yeh article aapko step-by-step samjhaye ga ke multimeter kaise kaam karta hai, aur aap usay basic fault finding se le kar motherboard level diagnostics tak kaise use kar sakte hain.
1️⃣ Multimeter Ki Types – Digital vs Analog
Zamana badal gaya hai – analog multimeters ab kam use hote hain aur digital multimeters ne unki jagah le li hai.
Digital multimeter zyada reliable, fast aur easy-to-read hota hai, is liye har naye student ko isi se practice start karni chahiye.
🔹 Analog multimeter – Manual reading, thoda mushkil
🔹 Digital multimeter – Accurate reading, beginners ke liye best
2️⃣ Multimeter Ke Basic Features – Yeh Har Student Ko Aana Chahiye 🧪
Multimeter mein kuch features aise hote hain jo roz kaam aate hain:
- Continuity Test (Beep Mode):
Kisi track ya wire mein break hai ya nahi, isko test karne ka tareeqa.
✅ Agar beep aaye to connection theek hai. - DC Voltage Measurement:
Battery ya charging port par voltage check karne ke liye use hota hai. - Resistance Checking:
Kisi component ka resistance value ya unka health status pata karne ke liye. - Diode Mode:
Diode, capacitor aur IC terminals check karne ke liye best mode.
3️⃣ Mobile Repairing Mein Multimeter Ka Real Use 🔍
📲 Charging Faults:
- Charger connect kar ke charging jack par voltage measure karna
- Battery terminals par 3.7–4.2V hona chahiye
- Charging IC test karna agar current flow nahi ho raha
🧠 Dead Phone Troubleshooting:
- Battery health check
- Power section ICs par voltage check
- Board short ka test diode mode se
📶 Network & Audio Issues:
- RF IC aur antenna line continuity
- Audio IC par voltage reading
- Speaker/jack ke terminals continuity
Note: PCB par har line ka test multimeter se easily ho sakta hai, bas sahi reading ka experience chahiye.
4️⃣ Advanced Techniques – Expert Banne Ka Raasta 🔬
Multimeter sirf basic nahi, advanced level repairing mein bhi powerful tool hai:
- Short Circuit Detection:
Board par koi component ya IC short hai ya nahi – diode mode se test karein.
Agar multimeter 0 ya near-zero dikhaye, to short confirm hai. - Voltage Mapping:
Charging line se le kar CPU tak har major section par multimeter se voltage flow check karna - Jumper Planning:
Track cut ho to continuity test se samajh aata hai ke jumper kahaan lagana hai. - Fuse Checking:
Mobile mein lagay chhote fuses ka resistance aur continuity check karna
5️⃣ Galtiyan Jo New Students Ko Nahi Karni Chahiye ❌
❌ Without knowledge live board test karna
❌ Probes ko careless tarike se PCB par touch karna
❌ Multimeter ko wrong mode par rakh kar check karna
❌ Heat zone mein multimeter probes chhor dena
Safety Tip: Hamesha battery ko disconnect kar ke board test karein, aur original probes use karein.
✅ Conclusion
Multimeter ek simple tool lagta hai, lekin iske zariye aap mobile ki har line, har IC aur har connection ko diagnose kar sakte hain. Agar aap multimeter ke functions samajh lein to aap 70% faults bina open kiye andaza laga sakte hain!
