This summary is not the rule. The rule text controls.
Sometimes a judge decides it would help the jury to see something in person instead of just hearing about it in court. This could be a piece of property, an object, or the actual location where something important to the case happened. If the judge thinks this would be useful, they can send the jury out as a group, with an officer in charge, to go look at it.
While the jury is out on this trip, no one is allowed to talk to them about anything related to the case. This keeps the jury from being influenced by outside comments or information. The only purpose of the visit is for the jurors to see the evidence with their own eyes, not to hear arguments or opinions about it.
This rule protects the fairness of the trial. It lets jurors get a clearer picture of the evidence while making sure nobody tries to sway their opinion during the outing.
