What moved the readout?
Caption-led silent film. All diagrams are illustrative.

00:00:00.000 — First recover a force that can be predicted.
MF-01 is a proposed measurement program. Establish the known-force reference and calibrate the complete instrument before testing a new surface.
Metric Flight proposed protocol. This drawing is not built hardware.

00:00:10.000 — A moving readout is not enough to identify its cause.
Thermal expansion, residual gas, electrical coupling and vibration can affect a force measurement. Use controlled interventions to separate them.
Illustrative traces; no experimental data. See MF-01 proposed protocol.
