The principle behind system check mode is simple: A sinusoid of the selected frequency is output with
a slowly increasing peak voltage until the desired acceleration/velocity/displacement setting is reached.
The default settings of 30 Hz and 0.1 inches work well with most shakers. However, any setting may be
used.
1. Place a displacement wedge on your shaker table. (Dispacement cards come in the cd case with
each order.)
2. Select the Test..Test Type..System Check menu command to switch to System Check Test
mode.
3. Open up a Time graph, displaying channel 1.
4. Turn on the shaker amplifier and any associated electronics.
5. Click the "Auto" button in the System Check Control . Watch the shaker table and input
waveform carefully. You should see a sine wave in the graph window and the shaker should begin
to oscillate at a visible level. With the default settings of 30 Hz and 0.1 inches you should see a
0.1 inch peak-to-peak displacement on the shaker and a 4.6 G peak sine wave on Channel 1.
6. Once you are convinced the system is operating properly or if you notice something wrong, click
the "Stop" button to turn the output off.
2.4.2 How to run a Sine test
How to run a Sine test
You have three ways of choosing which Sine test profile you would like to run.
1. If you would like to run the most recently used Sine test profile, select the Test..Test Type..Sine
menu command.
2. You may click on the TestType button on the toolbar, or select the Test..Test Type menu item
to bring up the Test Type selection box. Choose Sine and click on the "OK" button.
3. If you would like to run a Sine test from a saved test profile, select the Test..Open Test Profile
menu command or click the "Open test" toolbar button. A list of test names will be displayed.
Select Files of type "
VibrationVIEW Sine Profiles (*.vsp)" and select the test you wish to run. Click
the "Open" button to load that test.
To run the test, click the "Run" button in the Sine Control Center . Once the test begins, the
"Stop" button will turn red and the "Run" button will turn yellow, indicating that the test is starting. Once
the desired output level has been reached the "Run" button will turn green. To stop the test click the
"Stop" button. Notice the other buttons displayed in this control box. The "SweepUp," "SweepDown,"
and "SweepHold" buttons control the sweep direction. The radio buttons labeled Accel, Vel and Disp
control the parameter displayed for the demand and control readings for each of the eight input
channels.
You can also manually adjust the frequency by clicking the "Frequency" button. This will automatically
place the output into SweepHold mode and prompt you for the desired output frequency.
2.4.3 How to run a Random test
How to run a Random test
You have three ways of choosing which Random test profile you would like to run.
1. If you would like to run the most recently used Random test profile, select the
Test..Test Type..Random menu command.
