Power of spring as mechanical filter: 500 Nw/mm. Spring lifting and lowering time: less than 5 m/sec. Impact force measuring range: from 0 Nw to 2500 Nw. Force range within the space of time: 0.75 sec. for the peak force. Total length of test: 6 (six) seconds.

Number of tests per measuring point: 3 (three).

Total number of tests: 27 (twenty-seven). Three per height and per position.

Partial averages and final average. The computer calculates the average of the three tests per height and a final average of all three positions.
