ABSTRACT:
The apparatus comprises an actuator (23) that can be pushed from an extended position to a depressed position. When doing so, the actuator (23) first releases an impact body (32) to impinge against the sample (2), and then a catcher (40, 42) to be moved to the released impact body (32) for bringing it back. The passage of the impact body (32) is detected by a reed switch (28), which wakes up the processing circuitry and switches the same between two modes of operation. In the first mode, the circuitry displays a device status, and in the second mode a measuring result.
