Dominant Frequency
Setting for determining the dominant frequency.
In accordance with the type of building vibration to be measured, calculate
the frequency with the highest spectrum from the ratio of the dominant
frequency calculated from measured PPV and the regulated value specifi ed
in DIN 4150-3 as the dominant frequency.
• Line1 is ”Buildings used for commercial purposes,industrial buildings,
and buildings of similar design”
• Line2 is ”Dwellings and buildings of similar design and/or occupancy”
• Line3 is Structures that, because of their particular sensitivity to
vibration, cannot be classifi ed under
• lines 1 and 2 and are of great intrinsic value (e.g. listed buildings
under preservation order)
When No Line is selected, the frequency with the highest spectrum is
calculated as the dominant frequency from the FFT result.
Standard
Select the General mode when measuring according to DIN or ISO, select
SBR mode when measuring according to SBR. Evaluation values can be
displayed and stored according to those settings.
Delay Time
Displays the screen to select the delayed measurement time that is an
interval starting at the point the start key is pressed.
Select [Delay Time] and press the MENU/ENTER key. The delay time
screen appears.
The delayed measurement is invalid at Timer Auto store.
