  to return to the preceding page.   

There are three options available on the main menu: 

⊙

  Photometric Measurement 

This mode allows the user to measure Abs or transmittance at a fixed wavelength and K factor and 

print out. 

⊙

  Card Program 

The instrument can perform a required measurement such as quantitative measurement, DNA/Protein 

analysis etc. by loading a pre-programmed card into the extended interface of the instrument. If there is no 
pre-programmed card in the extended interface, this option is inoperative.   

⊙

  System Set 

This  mode  allows  the  user  to  specify  the  working  parameters,  such  as  backlight  working  mode, 

tungsten lamp On/Off, deuterium  lamp On/Off, control mode, time set, wavelength calibration, and dark 
current correction etc.
