To start, you can switch it on by switching the switch on it back, and also make sure that you have sufficient power supply. After you turn it on, you will have to wait for few minutes (seriously) for the instruments to calibrate itself. At the same time, you can start loitering around the lab and disturbing others who are busy with their works. Once it is ready, you can choose specific wavelength you want by pressing the "lambda" button on the right bottom. Then, you enter the wavelength you want, well, I am using 420nm. Then you put blank cuvette inside the purple hood and press the button next to the "lambda" for it to calibrate to the specific wavelength. Once it is done, you can put your sample and take the reading on the reading screen. It is that simple. How much this instrument worth, well I say roughly around RM15K (doesnt look like 15K to me)
