Abstract

PURPOSE:To make a data decision, etc., with a host device by performing the measurement of a measuring point almost simultaneously in accordance with a command from the host device through input means or communication means, thereby enabling catching the data as phenomena. CONSTITUTION:The measurements of measuring points are made by a controller 13 as a control means in such a manner that an analog/digital converter 5 or digital input/output means, etc., are driven in accordance with the command (condition for measurement) from the host devices, e.g. a computer or a diagnos tic device, through a ten keys switch 7 as input means or the communication means by a selection of a mode selection switch 9 as switching means. The numeric data is stored in a memory part RAM. So, the numeric data at the measuring points is measured almost simultaneously since a converter 5, etc., is actuated in high speed. Therefore, a timing deviation is hardly found between each measuring points, and the data can be caught as the phenomena. Also, the data can be transferred by means of connecting with the host device through the communication means by the selection of switch 9.
