Mode of operation

Manual

Action

Only one start input moves down head to reach and clamp the test surface from distance multiple of50mmand automatically starts the hardness cycle in automatic succession without breaking a phase; approach to the piece; clamping of the piece ; activation of reference surface; entire test cycle performance and release of piece.

Automatic compensation of deflection piece from 0 to50mm

Operativity

It can work if not levelled, inclined or near to vibration area, without loosing accuracy.
