How to Ground a Dagan Headstage
Please note that Dagan has changed most headstages. They no longer have the grounding port that they had in the past. Instead, the ground wire can simply be wrapped around the probe rod mounting screw, before screwing on the probe rod. Such headstages include the 7001, 4001, and 8024 series.
This does not apply to the PC-ONE headstages, which are driven, not grounded.
