Pulsing Valve and timer

training ari ni sangat best OKAY!!! selain kene buli dgn pakcik2 tua dalam group, we have hands on session..best sgt dapat bukak2 valve pastu pasang balik..baru la tau rupe diagfram tu macam mane..rubber disc, n etc etc laa..

Also dapat buat tuning utk Timer..sngat senang okay..insyaALLAH, boleh pass test..hihi

Baru la engineer macam ni..lalalala~
