Chaahe koi bhi phone ho keypad ya phir koi smart phone plus minus check karne ke liye multimeter ko beep range par set karna hai uske baad ek prov yani ek wire grounding par touch karna hai (jitne bhi golden border hote hain aur sim connector,memory connector aur jitne bhi silver color ka plate dikhega wo sare ground ke hote hain).jis pin par rakhne se beep bajega wo minus hai aur theek uske opposite wala plus ka point hota hai. aur shorting hame battery connector ke plus aur minus point par hi check karna hai.

FULL SHORT:-
agar battery connector ke dono taraf beep bajta hai to board full short hai. aur full short ke conditon me koi bhi phone ON nhi Rehta hai. sabhi phone dead hi rehta hai.

HALF SHORT:-
agar battery connector ke dono side reading aata hai.wo reading chaahe kitna bhi ho agr Display par dono side reading hold hoga to phone half short rehta hai. aur half short ke condition me 50% devices DEAD rehte hain aur 50% devices ON rehte but usme kuch na kuch problem hoga jaise phone heating Battery jldi jldi discharge hona aur bhi kai saare probms ho sakte hain.

NO SHORT:-
agar battery connector ke ek side 300 to 600 ke beech reading aaye aur dusre side kuch bhi reading nhi aayega ya reading aa kar jayega to phone short nhi rehta hai. aur agr phir bhi Mobile ON na ho, to, koi aur problem rahega.
