ඔබේ PHONE එකේ තත්වය බලමු, How to Check Cell Phones Quality Using IMEI

.

අපි බලමු ජංගම දූරකථනයක IMEI (International Mobile Equipment Identity ) number උපයෝගී කරගෙන එය නිශ්පාදනය කර ඇති රට සොයා ගන්නා ආකාරය.හා එමගින් දූරකථන‍යේ තත්වය තීරනය කරන ආකාරය.  අළුත් හෝ පාවිච්චි කල දූරකථනයක් මිලට ගැනීමේදී එය ඔබට වැදගත් වෙයි.

     IMEI අංකය බලා ගැනීමට, *#06#  type කරන්න. රූප බලන්න.

බැටරිය ගැලෙව්වමත් පුලුවන්,

මෙහි IMEI අංකය 357613004448485 මෙහි 7,8, අංක දෙක තමයි දූරකථන‍ය නිපදවපු රට.

                          3 5 7 6 1 3 0 0 4 4  4 8  4  8  5

                 1 2  3  4  5  6  7  8   9 10 11 12 13 14 15

    ඒ අනුව,.....

If the 7th and 8th digits is 02 or 20 then this indicate your mobile or cell assembled in the Emirates Its have very bad and also poor quality.

If the 7th & 8th digits is 13 or 31 then it indicates your cell phone is built in Azerbaijan its i too bad quality also dangerous for health.

If the 7th and 8th digits are 08 or 80 than this indicate your mobile or cell is  made in Germany it is fair mobile quality.

If the 7th and 8th digits is 01 or 10 then this indicates your cell is made in Finland It is high quality.

If the 7th and 8th digits are 00 than this indicate your mobile or cell is made in Real Original Mobile Factory means its the best quality phone.

If the 7th & 8th digits is like 03/30 or 04/40 then  it means your mobile or cell  is manufactured in China, but mobile quality good. Fully not good like 01 or 10. 00,

If the 7th and 8th digits is 03 or 30 then this indicate your mobile or cell assembled in the Korea.

If the 7th and 8th digits is 04 or 40 then this indicate your mobile or cell assembled in the China.

If the 7th and 8th digits is 05 or 50 then this indicate your mobile or cell assembled in the Brazil ,u.s.a,or finland.  

If the 7th and 8th digits is 06 or 60 then this indicate your mobile or cell assembled in the U k , China , Maxico , Hong Kong .

If the 7th and 8th digits is 07,70 or 19,91 then this indicate your mobile or cell assembled in the Finland .

MULTIMETER-2

 

What is a multimeter?

•A multimeter is a devise used to measure voltage, resistance and current in electronics & electrical equipment

•It is also used to test continuity between to 2 points to verify if there is any breaks in circuit or line

•There are two types of multimeter Analog & Digital

–Analog has a needle style gauge

–Digital has a LCD display (Referenced during this PPT)

 

Meter leads

•Red meter lead Is connected to Voltage/Resistance or amperage port Is considered the positive connection

•Black meter lead Is always connected to the common port Is considered the negative connection

•Probes Are the handles used to hold tip on the tested connection

•Tips Are at the end of the probe and provides

Measuring Voltage

•Voltage (V) is the unit of electrical pressure; one volt is the potential difference needed to cause one amp of current to pass through one ohm of resistance

•Voltage is broke up into 2 sections AC & DC

Alternating Current (AC) is house voltage (110/220vac)

Direct Current (DC) is battery voltage (12vdc)

•Be very careful to not touch any other electronic components within the equipment and do not touch the tips to each other while connected to anything else

•To measure voltage connect the leads in parallel between the two points where the measurement is to be made. The multimeter provides a parallel pathway so it needs to be of a high resistance to allow as little current flow through it as possible 

 

Measuring Resistance and Continuity   

·        Resistance (Ω ) is the opposition to current

 

•Resistance is measured in Ohm's

•Disconnect power source before testing

•Remove component or part from system before testing

•Measure using lowest value, if OL move to next level

•Testing for continuity is used to test to verify if a circuit, wire or fuse is complete with no open

•Audible continuity allows an alarm if circuit is complete

•If there is no audible alarm resistance of 1ohm to .1ohm should be present 

 

Measuring Current

•Current (amps) is the flow of electrical charge though a component or conductor

•Current is measured in amps or amperes

•Disconnect power source before testing

•Disconnect completed circuit at end of circuit

•Place multimeter in series with circuit

•Reconnect power source and turn ON

•Select highest current setting and work your way do
