Answer
Kontrèman ak sous dlo bobin estanda, sous dlo vag yo raman enspekte nan wotè gratis paske fòm nan 'vag' difisil pou mezire repete. Paramèt enspeksyon prensipal la se 'Chaj nan Wotè Travay'. Sa a mezire lè konpresyon prentan an nan yon dimansyon axial espesifik $H_1$ epi anrejistreman fòs $P_1$ la. Yon dezyèm pwen $H_2$ souvan mezire pou verifye to prentan $k = \frac{P_2 - P_1}{H_1 - H_2}$. Additionally, 'Radial Wall' and 'Wire Thickness' are inspected via micrometers, and the 'Gap' (for gap-type springs) or 'Overlap' (for overlap-type) is checked to ensure no interference occurs during full compression.
