Abstract

PURPOSE: To automatically acomplish the range interchange and to make it possible to accomplish the recording operations with a preset measuring accuracy by subjecting only the lower unit, which has been converted in an analog-digital manner from input signals, to the analog-digital conversion and by accomplishing the recording operation through the power supply to a recorder.
CONSTITUTION: Analog signals measured are adjusted to the designated input voltage of an A/D converter so that they are converted in an analog-digital manner. Only the lower unit of the digital output is converted in an analog-digital manner and fed as input signals to a recorder. For example, in case the input signals are linearly varied, they are drawn in the A-B1 on recording paper if the input signals are at a level from 0W1mV. The value exceeding 1mV is drawn in the form B'1-C1. The following recording operations are accomplished in a similar manner.
