Abstract
PURPOSE: To make measurement of high precision possible while eliminating the need to bend a lead wire and for clipping by a clip, by equipping a probe at the tip of a sliding piece, which slides on the substrate of a measuring instrument, via a coil spring.
CONSTITUTION: On substrate 3 of a measuring instrument, sliding pieces 6 are radially provided and probe 8 is equipped via coil spring 7 at one terminal closer to measured-body installation hole 4 of probe 8 is brought into contact with the lead wire of a measured body by the proper contact pressure of coil spring 7. In the above-mentioned constitution, turning rotary disk 10 makes sliding piece 6 move toward linear IC1 in the center and meet the root of lead wire 1b, and consequently characteristic measurement is possible only through the one-touch operation of the rotary disk. Consequently, the contact pressure can be kept adequate without any error contact to the lead wire, so that the high precision measurement will be taken.
