@@civilengineerfbh277 , without tripod , the free fall cannot be controlled as required of 45 cm , OK . Here that happened . The labourers made small falls towards last part . This gives higher N values , OK . Plz. ensure correctness in the testing otherwise it's of no use , rather do buildings on assumed SBC or take advice of illiterate masons . You didn't mention the dia. of the sampler .
Bro why so careless on the field? A rod should always be straight and tightened for the uniform distribution of applied load. more than that safety always comes first. Just Imagine what would happen if 63.5 kg load struck the bear foot.
