CALIBRATION METHOD IN MULTI-PEN TYPE RECORDER

摘要

PROBLEM TO BE SOLVED: To easily and surely perform calibration for a multi-pen type recorder which puts multiple data, sharing the same vertical axis and horizontal axis on a recording paper. ;SOLUTION: In a such state that common zero point calibrating voltage is inputted to a plurality of recording pens 11₁-11₄ of a multi-pen type recorder, the positions of all the recording pens 11₁-11₄ are positioned on the first ruled line L₁ of a recording paper 10 with manual operation. Continuously, in such a state that common full-span point calibrating voltage is inputted to each recording pens 11₁-11₄, the positions of all the recording pens 11₁-11₄ are positioned on the second line L₂ of the recording paper 10 with manual operation.;COPYRIGHT: (C)1997,JPO
