Abstract
PURPOSE: To obtain a comparatively cheap system capable of quick correspondence to the change of measurement specifications by a method wherein a switching system is constituted so that multimeasuring instruments constituting a measurement device are made to fit to all of multiterminals of a unit to be measured.
CONSTITUTION: When measuring instruments 11, 12...1m of a measurement device 10 are connected to terminals (1), (2)...(n) of a unit to be measured, respectively, then, in the 1st change-over switch 41, selection switches 41a, 41b...41m are connected to lines 44a, 44b and 44c, respectively and in the 2nd switch 42, selection switches 42a, 42b and 42n are connected to lines 44a, 44b and 44c, respectively. With this constitution, all kinds of combinations are possible between the measuring instruments of the measurement device 10 and a unit to be measured 20, and if a maximum of l pieces of lines are required, the total number of contacts of (m+ n)×l is enough. And further, a quick measure can be taken against a change of measurement specifications.
