摘要： The present invention is to provide a multimeter having an erroneous insertion prevention apparatus of the simple structural and space saving type. The multimeter (1) of the present invention comprises a rotary switch (3) for selecting the measurement function, a common terminal hole (20) for plugging a connector of a test probe, selective terminal holes (21, 22, 23) for selectively plugging the connector of the test probe, and shutter plates (4, 5) for selectively opening the selective terminal holes (21, 22, 23), wherein the rotary switch (3) has convex parts (32, 33) which are moved along with the rotation; the shutter plate (4) has a hole (41) corresponding to the common terminal hole (20) to be rotatable on the center of the common terminal hole (20) which is the rotation shaft center while having a recess part (42) which can be hung and fitted in the convex part (32) to be rotatable to open either of the selective terminal holes (21, 22) by moving the convex part (32); and wherein the shutter plate (5) has a recess part (52) which can be hung and fitted in the convex part (33) to be rotatable to open and close the selective terminal hole (23) by moving the convex part (33).
