3-2 Preparation for test
1) Shape and size of specimens
The maximum weight and the maximum size in case of face drop of a specimen should be within the
rated ranges. (See §8. Performance and specifications)
2) Check of each section
Check each section (the pneumatic pen cylinders for fixing a specimen, in particular) for normal
condition before starting the test. (See Fig.2)
3) Drop height setting
Set the height setting pointer to an optional position of the scale, and fix it by fastening the knob.
The drop height scale shows the distance from the upper face of the base to the pneumatic pen
cylinder center. Set the drop height by adding the distance from the pneumatic pen cylinders to the
lower face of specimen to the drop height.
