Le probl\u00e8me est que le couple requis n'est souvent pas clair au d\u00e9but d'un projet : un panneau prend du poids apr\u00e8s l'ajout d'un \u00e9cran, un faisceau de c\u00e2bles change, un joint est modifi\u00e9, une poign\u00e9e est am\u00e9lior\u00e9e ou une variante utilise un panneau plus grand. Si la charge est stable et pr\u00e9visible, un couple constant est plus facile \u00e0 contr\u00f4ler. Si la charge est susceptible de varier, un couple r\u00e9glable offre aux ing\u00e9nieurs ou au service apr\u00e8s-vente la marge de man\u0153uvre n\u00e9cessaire pour ajuster le fonctionnement final. Une mauvaise d\u00e9cision se r\u00e9v\u00e8le g\u00e9n\u00e9ralement plus tard sur le terrain : le panneau d\u00e9rive, semble trop rigide, ne reste pas ouvert ou pr\u00e9sente un fonctionnement diff\u00e9rent d'une unit\u00e9 \u00e0 l'autre.<\/p>\n\n\n\n<h2 id=\"what-each-one-is-best-for\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_each_one_is_best_for\"><\/span>\u00c0 quoi sert chacun d'entre eux ?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Couple constant<\/strong> Elle est r\u00e9gl\u00e9e sur une valeur de r\u00e9sistance valid\u00e9e et n'est g\u00e9n\u00e9ralement pas modifi\u00e9e sur le terrain. Son principal avantage pour les \u00e9quipementiers r\u00e9side dans sa r\u00e9p\u00e9tabilit\u00e9 : une fois s\u00e9lectionn\u00e9e, cette pi\u00e8ce s'installe de la m\u00eame mani\u00e8re sur des milliers d'unit\u00e9s.
