5.3 Measuring
• Grip the Schmidt OS-120PM by the handle on the housing (1). Exert a light pressure against the
test surface 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. Additionally make certain that
the joint to be tested is precisely in the middle of the circular opening of the housing (1) in position
A. This will ensure that the hammer head (7) impacts on the surface of the joint. (See the picture
below.)
• Using the reset lever (2), bring the hammer (3) to position B.
• Trigger the impact by pressing the trigger button (4).
• Read the rebound value from the scale (5).
Repeat the procedure as many times as the standard you are working to requires. For example, EN
12504-2 requires a minimum of 9 rebound values for calculating the median.
The rebound value determined in this way can be used to give a classification by means of the
evaluation table. (See chapter 5.4).
When the measurement is completed:
• Check the Schmidt OS-120PM on the anvil (see chapter 4.1)
• Put the Schmidt OS-120PM into the neutral position. i.e. set the OS-120PM on a horizontal
surface (e.g. leave it on the anvil after the control check), set the control knob (6) to position V,
depress the reset lever (2) to bring the hammer (3) to position (B) and lock it in place by pushing
the lever (2) upwards. The Schmidt OS-120PM may now be stored in the case.
