Module 1.1 – Simple Sine Test

March 29, 2018

1. Configure the Hardware

a. Click Configuration > Hardware
b. Set the Network Card Address to Demonstration Mode
c. Click Apply

2. Configure the Inputs

a. In the VibrationVIEW Configuration dialog box, click the Inputs tab
b. Set the sensitivity of Ch 1, Ch 2, Ch 3, and Ch 4 to 100mv/g
c. Click OK

In real-world testing, the accelerometer’s sensitivity would be 10mv/g. However, the sensitivity must be increased in order to hear the features of a real-world test in Demonstration Mode. The increase in sensitivity will make the sound card’s rendition of the real-world test sounds audible.

3. Configure the System Limits

For Demonstration Mode only!

a. Click Configuration > System Limits
b. Set the limits as displayed in the image below:

Sine test settings module 1.1

c. Click OK
d. Save the test as Name_SimpleSine1

5. Create the Graphs

a. Close any existing graphs
b. In the main ribbon, click the New Graph button

c. Graph 1 configuration

Graph Type: Acceleration vs. Frequency
Graph Traces:
- Control Loop Traces: Demand, Control [Last Pass], Tolerance, and Abort
- Input Channels [Last Pass]: Ch 1 and Ch 2

d. Click the Insert Graph button

e. Graph 2 configuration

Graph Type: Acceleration vs. Time
Graph Traces:
- Input Channels: Ch 1 and Ch 2

f. Click Insert Graph
g. Graph 3 configuration

Graph Type: Displacement vs. Frequency
Graph Traces:
- Control Loop Traces: Demand, Control [Last Pass], Tolerance, and Abort
- Input Channels: Ch 1 and Ch 2

h. Click OK
i. In the main ribbon, click the Autoscale button (CTRL+F)

6. Run the Test

a. Click the Start the Test button

b. Watch and listen while the test is running. You should hear the test as the frequency rises and visually observe the effects of the sine test on the device under test (DUT).
c. After the Ch 2 resonance appears, click View > Cursor Window (CTRL+D) to view the resonances. Hover the cursor near resonance and press the shift key. The cursor will snap to the resonance. Continue holding shift and press the insert key. The annotation will be inserted at the “snapped to” peak.
c. Save the data in an appropriate location

7. Create a Report

a. In the main ribbon, click the Report button

b. In the report, include the following information:

Customer information: Name, Module Number, and Course Name
Graphs:
- VibrationVIEW Screen
- Velocity
- Transmissibility
- Acceleration Time History
- Demand, Control, Tolerance, Abort
- Channel 1, Channel 2

Your report should look like the following:
