2.2 Electrode Section
12. Opposed Electrode
Connects with the HI of the V SOURCE terminal in volume resistivity measurement to
become a high-voltage application electrode. Voltage is applied between the main electrode
and this electrode.
Place a sample to cover the ring electrode, and put the opposed electrode over it.
Pass the feed terminal through the two holes on the opposed electrode, and press the op-
posed electrode down to the end to stick fast to the sample. It floats a few mm by the main
electrode spring. However, it is pressed down by closing the cover, so that each electrode
and the sample stick fast to each other.
Figure 2-3 Opposed Electrode
The opposed electrode is just inserted but not locked. It may fall by opening the cov-
er. Do not turn the 12704A upside down with the cover opened.
