Node requires dynamic data to be converted to numerical data. This enables the program to
process and record all acquired data points.
The updated VI allows the user to input excitation voltage, gain, and gage factor; thus the
program can be used with different hardware conditions without major alternation.
Updated software for Vibration Measurement Laboratory enables saving time domain
data without alternating the program.
Step-by-step tutorials for constructing the programs are included in the updated
laboratory instructions, which are contained in Appendix 3 and Appendix 4.
