Warning!

Check the settings before performing a 
measurement! This applies in particular for the
impact direction and for the shape and time
coefficient.

4.1

Impact Direction

• Select the symbol for the desired impact direction.
The rebound value is automatically corrected according
to the preselected impact direction.

4.2

Mean Value

The mean value is calculated from the number of test
impacts n entered or after a measurement series has
been completed by pressing the END key.
• Where possible, enter at least n = 10 or n = 12 

(see under “Mx”, example on page 9).

The actual mean value is displayed after every test
impact.

4.3

Measure Series Number

• At the start of a measurement series, you can enter a

number (max. 6 figures).

The number is automatically incremented by 1 after the
first test impact of the new measurement series.
