• Repeat the functional check.
If the mean value is still out of tolerance, the instrument must be taken to an authorized service
centre for re-calibration.
4.2 Preparations
• If necessary, use the grinding stone to remove cement residues from the test surface.
• The hammer (3) must be fixed at position 75 on the scale (5) and the control knob (6) turned to
the desired position V (for testing on vertical surfaces) or H (for testing on horizontal surfaces).
4.3 Measuring
• Grip the OS-120PT by the handle on the housing (1). Exert a light pressure against the test sur-
face towards the side where the contact surfaces (A) of the housing (1) are located. This ensures
that the contact surfaces (A) lie flush against the surface (see the pictures below).
• Depress the reset lever (2) to bring the hammer (3) to the loading position (B).
• Trigger the impact by pressing the trigger button (4).
• Read the rebound value from the scale (5).
