Incorrect type of the impact device will lead to erroneous result.
4.1.2 Impact direction setting
The instrument offers two methods for correction for non-vertical impact direction: automatic and manual.
With manual correction the user has to specify the actual impact direction. In automatic mode the
instrument will find out the impact direction itself and apply the appropriate correction.
Press arrow keys or F2 key to navigate to the desired
item.
Press
or F3 key to confirm the selection.
Press
key to cancel the change and close current
dialog box.
If AUTO item is selected, the impact direction will be detected according to the rebound signal of the
impact body and the measurement value will be corrected automatically by the main unit.
Note:
AUTO item is disabled for G type of the impact device.
The main unit detects the impact direction correctly only after base calibration.
If only vertical down measurements are performed, disabling AUTO mode is preferable.
