As shown in the figure, the measurement electrode 7 is made of a round rod having a large diameter cylindrical portion (head) 8 at the top, and is made of a metal with good conductivity. Also,
An auxiliary electrode 9 is detachably attached to the head 8 of the measurement electrode 7. The auxiliary electrode 9 is made of a metal with good conductivity and high elasticity, such as phosphor bronze, and has a ring shape in which some parts are discontinuous. The height of this auxiliary electrode 9 is several mm higher than the height of the head 8 of the measurement electrode 7, and as shown in FIG. When the auxiliary electrode 9 is inserted into the portion 8, the upper end surface of the auxiliary electrode 9 protrudes above the upper end surface of the measurement electrode 7 to form a measurement terminal surface 11. The attachment and detachment of the auxiliary electrode 9 from the measurement electrode 7 is carried out by expanding both ends of the auxiliary electrode 9 of the ring body against elasticity, and the auxiliary electrode 9 is tightened by the restoring force of the ring body. Stick to 7.

The electrical characteristics are inspected while ensuring close contact between the electrode and the auxiliary electrode 9. Then, the measurement terminal surface 11 of the auxiliary electrode 9
When the auxiliary electrode 9 is worn out, the auxiliary electrode 9 is removed from the measuring electrode 7 and a new auxiliary electrode 9 is attached to the measuring electrode 7. In this way, the auxiliary electrode 9 can be easily inserted and removed, and since the measuring electrode 7 does not need to be replaced, there is no need to modify the circuit, and the working time is shortened, thereby preventing a decrease in the operating rate of the device. Note that the wear of the measurement terminal surface 11 of the auxiliary electrode 9 is directional. Further, the auxiliary electrode 9 has a ring shape. Therefore, by rotating the auxiliary electrode 9 by, for example, 45 degrees with respect to the measurement electrode 7, the portion of the measurement terminal surface 11 of the auxiliary electrode 9 that the lead 13 comes into contact with is an unused measurement terminal surface with no wear. It becomes 11. Therefore, by employing the auxiliary electrode 9, the number of times the measurement electrode is used is significantly increased compared to the conventional method.

Therefore, the operating rate of the device is improved. Additionally, when replacing the electrode, it may be sufficient to simply rotate the auxiliary electrode, which has the advantage of extending the life of the electrode. Furthermore, since the lead and the auxiliary electrode are in close contact with each other, there are many effects such as stable electrical characteristic testing.
