6–32 Blastware Operator Manual
Blastware includes a number of built-in weight tables, which you may use as-is or customize. To
save new weight tables, enter the desired Frequency and Weight values and click on Save and
Exit. A dialog box will appear where you can enter the name for the .fwt file and select the
destination directory.
6.9.10 Scale
This command changes the measurement units and offset value for a waveform.
To scale a waveform, choose Scale from the Process Menu. The following dialog box appears.
Choose a waveform to scale in the first drop–down menu. Enter a scale factor to be applied to the
waveform. Select a waveform window to display the new waveform. Enter an offset value, if
required. Enter a name for the new waveform In the Name result box. Finally, enter the
abbreviation to represent the measurement units of the resulting waveform.
WARNING: The Result units text box names units only. This text box does not check to
ensure the actual waveform result units match the units named in this box.
6.9.11 Remove Offset
Some recorded waveforms may contain a DC offset. Visually, a waveform containing an offset
appears to be shifted a constant value above or below the X axis. The system does not
automatically remove all offsets because a user may want to include them purposely. Using this
command, you can remove the offset from a waveform. The Blastware program removes an offset
by subtracting the average.
Note: You can manually adjust the offset using the scale command, see above.
To display the Remove Offset dialog box, open the Process Menu and choose the Remove Offset
command.
