The electric field within a closed, empty conductor is zero, so the cup shields the object placed inside it from any atmospheric or stray electric fields.
Connect the outer or shield connection of the BNC connector to the outside electrode, then connect the inner conductor of the BNC connector to the inside electrode.
将BNC的外壳或屏蔽连到外电极,然后把BNC连接器的内导体连到内电极。
