○ The instrument can measure current and voltage, which generates from a photoelectric ceramic materials. ○ The instrument must have D.C. voltage and current source, which can apply more than 1kV/100mA, and can be programmed to perform source-measurement as a function of a stepped voltage and current. ○ The instrument can measure photocurrent and voltage of various plate-type samples in the range of several tens of fA ~ ㎂ and 10㎶ ~ 10mV. ○ The instrument can store more than 1,000 reading memory.
