Bonjour ,j'ai la même machine ,plaise ,j'ai un problème de changement de vitesse,si tu peut me faire un vidéo comment changé les vitesse avec le bras de vitesse et comment il est branché a la boîte vitesse.

The SPT begins at 2:00 but the camera is not focused on the penetration. No way to demonstrate to students what the actual blowcount is (it isn't 39).

where's this place? which country?

this is CTP or SPT?

Did you see the technician gathering the sample? Sloppy!!!!! The person who put this video should know better.
