Adding several conditions to a custom IC, comparing the measuring value with the reference range value, this apparatus can select the good quality IC fast and correctly at an auto or manual mode. The apparatus performs the steps of: storing a needed program at a one-chip computer (14); composing a peripheral circuit peak detector (13), amplifiers (OP1-OP6), A/D convertor (22), driving circuit for step motor (14), signal generator (3), and latch buffer (21)) to add a suitable condition for measuring; and interfacing a printer circuit (25) to print the data.
