UUNUUew
Creates a new test setup based on the present test setup, so, BEFORE you press
this button you should select the Test Setup that best matches your needs from
the drop down list to the right of the Setup Name label. The operator must
specify a new name in the Setup Name field then click the Apply button. The operator can
then make changes to the test setup. Once changes are complete, the operator should then
click the OK button to save the changes.
UUDUUelete
This deletes the present Test Setup. The operator will be prompted to confirm
that he/she wishes to delete the setup.
UURUUename
This allows the operator to rename the present Test Setup. The operator must
enter a new name in the Setup Name field, then click OK.
Setup Name
This is a drop down list that contains all of the test setups that have been created by the
operator. If you click on this box, a list of all setups stored in the program will appear.
Clicking on one of the setups loads it into the FwdWin program. It is useful to include
descriptive information in the setup name for easy identification (when you operate an
FWD/HWD for a while, you’ll create MANY setups).
Comment
The operator can use this
line to include additional descriptive information regarding the present test setup.
Options
The options box contains three program controls:
Sampling Window
For each drop the system samples the load and deflection signals
for a period of typically 60 milliseconds. This parameter also
controls the range of the time axis on the time-history plot (see
“Time History Plots” later in this chapter).
Smoothing
The Smoothing (or Smoothed Peaks Option) is a special feature, which ensures that the
influence on the load and deflection peak values from possible undesired, high frequency
components in the load cycle will be reduced to a minimum. Correlation trials have proved
the value of this option. Nevertheless, use of this feature is left to the discretion of the
operator or responsible engineer. For further information, please contact Dynatest.
Preserve Temperatures
Some agencies manually measure asphalt temperatures at time of test in addition to or in-lieu
of the surface temperature measurements. These measurements are labour intensive, so they
cannot be done at each test point. If this box is checked, FwdWin will record the last entered
asphalt temperature at each successive test point until a new temperature measurement is
recorded and entered into FwdWin.
