Components Testing

RINGER \ LOUD SPEAKER:-

ye dono ek hi hota hai aur inka kaam mobile me jitne bhi multimedia sounds bahar hote hain wo saare isi se bahar hoti hai.

RINGER \ LOUDSPEAKER check karne ke liye multimeter ko Beep Range Par set karte hain phir Ringer ke dono wire ya point par multimeter ka dono wire ka pin . touch karenge. minimum Beep ke sath 008 - 012 reading aana chahiye ek normal ringer bajne ke liye. agr sirf beep aaye ya phir sirf reading aaye to bhi ringer or loud speaker kharab rahega.
Ye value Compulsory nhi hai,, Ringer ko direct phone me lagakar check karke dekhna hai,, kayi baar value 8 se kum rehne par bhi ringer sahi awaz me bajta hai.

RICEIVER \ EAR SPEAKER \ SPEAKER:-

ye Teeno ek hi hota hai aur inka kaam mobile me by default call par ssaamne wale ki awaj sunane ka kaam krta hai aur iska single use hota hai.

ear speaker \ speaker \ receiver: check karne ke liye multimeter ko Beep Range Par set karte hain phir Receiver ke dono wire ya point par multimeter ka dono wire ka pin touch karenge. minimum Beep ke sath 025~035 reading aana chahiye ek normal Receiver ko kaam karne ke liye. agr sirf beep aaye ya phir sirf reading aaye to Riciver (ear speaker \ speaker) kharab rahega.
value matter nhi karta kayi baar value bahut kum aane par bhi Receiver Normal Awaz me play hota hai,Direct phone me laga kar check karna hai, agar baj rha hai to theek hai,, otherwise change karna padega.

MIC Checking (20K Ohms Range)

Mic Microphone Apne mobile se apni Awaz Saamne wale tak pahuchane ka kaam karta hai.aur saamne waale ki awaz apne tak pahuchata hai. ya phir aese kaha ja sakta hai, microphone Sounds Signals ko Electric Signal me convert karta hai karne ke liye multimeter ko 20K (Ohms Range) par set kar ke mic me phook marenge. agar reading badhe to mic sahi hai. agar phook maarne se reading na badhe ya sirf 0.something hi badhe to mic kharab rahega.

testing

Battery ka voltage check karne ke liye multimeter ko 20V par set karenge. phir red wire ke point ko plus par aur black wire ke point ko minus par touch karna hai.

• Battery ka nominal aur minimum voltage 3.7V or 3.8V hota hai
• battery ko jhatka maarne ke liye Jhatka machine ko 12V par set karte hain. phir red wire ke point plus par aur black wire ke point minus par rakhne par agar jhatka machine ka light Dim ho to battery jhatka yani ki battery charge ho rha hai

Components Checking with jhatka machine

sabse pehle hame check karna hai ki jhatka machine ko 1.5 voltage par set karne ke baad kitna voltage aata hai.ye check karne ke liye hum multimeter ko 20V par set karenge. uske baad multimeter aur jhatka machine ke red wire ko red aur black wire ko black par rakhkar check karenge. Aksar Jhatka machine 1.5V par 5V Out karta hai jisse apna koi bhi components fuse ya phir short ho sakta hai, iske liye hum panel meter aur DC power supply ka use karenge jo neeche list me diya hai wo components check karne ke liye

1. VIBRATOR
2. FLASH LIGHT
3. LED LIGHT
4. CAMERA KA FLASH LIGHT
5. KEYPAD KA LED

Ye paach cheezein check karne ke liye jhatka machine ko 1.5 to 3 Voltage par set karte hain.
