Control unit
The control unit panel is provided with [POWER], [DROP], [SET], [RESET] push-button switches,
[500mm] selector switch, and [TOTAL] (total counter). A sequence control is mounted inside. The
drop operation of the tester is controlled by these component parts.
The push-button switches on the operation panel function as follows.

be standing by.
For turning off the power supply, push this switch again. This switch is also used if an operation
trouble occurred or if the operation is stopped urgently.
The pneumatic pen cylinders are controlled to fix the specimen when the power supply has been
turned off.
2) [DROP] push-button switch
This push-button switch is used for dropping a specimen.
A specimen must be set to the specimen supporting base as a requirement for drop operation.

supporting base are protruded to fix a specimen. The rod can be adjusted to an optional speed by
the speed controller.
