The other end of the check
A reference target, a retained history and a meter each have another end that the research must keep in view.
An average needs its two readings
Two targets around the clamp offers an attractive cancellation: one reading rises as the other falls. The average is useful because the model makes a shared rotation explicit. Change the two arms or let their supports turn differently and the cancellation becomes incomplete. The individual readings remain part of the result.
The checkpoint someone else kept makes a similar demand of history. A receipt is useful only in relation to a view that survives the restoration being tested. Two signed statements can disagree without either signature detecting the disagreement alone.
The instrument joins the circuit
The circuit under the meter takes this question to a small passive electrical bench. The meter remains connected while the capacitor charges and discharges; a separate resistor deliberately changes the load. A quiet display at the end is a reading of that whole arrangement.
The January 24 exchange leaves different next tasks with the existing teams. Build and inspect a reference mock-up. Enact a custody boundary. Repeat a known electrical step with the observation timing and loading retained. These are practical connections between methods, not evidence of a common source.
