'19/4/10'
I do the heating test. I learn about how to measure the small current by using the current amplifier, current probe and oscilloscope. By using current amplifier, the value that i get i need to devide by 20 because the current amplifier is set to 20.
'16/4/10'
Today is not very busy. I just study the theory of wall mount test. My HOD, Chiou Ling ask me to go to Jalan Pasar to buy some electronic equipments.
'15/4/10'
Today i have learn about the screw test. I use the electric screw driver with torque. I need to calibrated first that torque depend on screw size. For the metal screw, the screw are loosen and tighten for 5 times each. For the plastic screw, the screw are loosen and tighten 10 times each.

Today i just set up the equipment to do the heating test. For this test, there are devided into 2 parts. For the first 4 hours, i need to set the power supply to 264v/50Hz. For the next 4 hours, i have set the power supply to 99v/60Hz.
'13/4/10'
I learn about bump test and also impact test. For the bump test, i need to perform W/I test before and after that test. For the impact test, i used the impact ball and impact hammer to test the tv.
'12/4/10'
Today is not very busy. I just recap what i have learn before. I read the manual lab to get more information and understanding.
'9/4/10'
I have learn about how to do the withstanding and insulation test. For this test, i want to know how strong the tv that can maintain from the outside voltage. For the withstanding test, it is more to protect the tv. For the insulation test, it is more to protect the user.
'8/4/10'
I was learn about withdrawal of main plug measurement. I need to test the tv in 3 stages which is ON, OFF and STANDBY mode. For this test, i have set the power supply to 264v/60Hz.
The main purpose for this test is we want to know how many current left inside the board ( switch ) when the user pull out the plug.

'7/4/10'
I do the soldering works for the complicated circuit. En Fattah was explained to me about the safety way to do the soldering work. I used mask and solder fan during the soldering work.
I also study and practice about the leakage current measurement. For this test, i need to take the value from oscilloscope during TV in ON, STANDBY and OFF condition. The purpose is to check either the leakage current is in save condition or not.
