Hey guys, bought a sman3 a few months ago, only used it about 10 times so far. It is a great tool!! Anyways now it does not show my subcooling, it will show my sh , temps lsp, vsp, idwb. Idwb, real time temps from my temp clamps, but it won't calculate my sub cooling it just shows 0L just wondering if this has happen to anyone. It's I really don't need it to calulate my sc, but it's nice to get what u pay for.
