5. Solder the shield of the cable to the copper round plate using solder wick.
Troubleshooting
When the short residual resistance is out of the limit, check the fixture
connection, the shorting plate, and the surface of the electrodes. If the surface
of the electrode is damaged, electrode assembly replacement is required for
restoring proper electrical performance.
When the short residual inductance is out of the limit, check the angle of the
semi-rigid cables in back of the electrode assemblies. The angle should be
close to 90
º. Also check the shield of the semi-rigid cables are connected only
at the copper round plate.
Do not polish the surface with powder to protect the electrode.
