7.3.5 End of Timed Test
End of Timed Test ( Sine Stop Code )
This code indicates that the test was run for the scheduled time duration (as defined in the
Test Schedule dialog box). When this code is displayed, the test is complete and the output is
turned off.
7.3.6 Front Panel Start
Front Panel Start ( Sine Stop Code )
This code indicates that the test was started using the "Start" switch on the front panel of the
VibrationVIEW I/O unit. While this code is displayed, the system is in the starting mode, as described
in the Starting Test stop code. Once the desired level has been reached, the test mode will change
to Running Test .
7.3.7 Holding Frequency
Holding Frequency ( Sine Stop Code )
This code indicates that the output frequency is held at a fixed value. The frequency sweep can be
frozen using either mouse control in the
Sine Big Display dialog box or by clicking the "Hold Sweep"
button in the Sine Control Center .
7.3.8 Input channel N is clipping
Input channel n is clipping ( Sine Stop Code )
This code indicates that the input signal to channel n is exceeding the allowable input voltage range of
+/- 10 volts and is being distorted by clipping. To solve this problem, use an accelerometer with a
lower mV/G sensitivity rating.
The maximum allowable acceleration readings for various accelerometer sensitivities are shown in the
table below.
Sensitivity Maximum Acceleration
10 mV/G 1000 G peak
20 mV/G 500 G peak
50 mV/G 200 G peak
100 mV/G 100 G peak
1000 mV/G 10 G peak
7.3.9 NI-DAQ error code
NI-DAQ error code ( Sine Stop Code )
This code indicates that an error occurred while reading input channels from the National Instruments
data acquisition card. This error typically happens when another program (e.g. VibrationAnalyzer) is
attempting to read data from the data acquisition card at the same time as the
VibrationVIEW program.
Do not run the VibrationAnalyzer program while a sine test is running.
To clear this error condition, stop and resume the test. That is, click the "Stop" button, click the "Run"
button and select "Yes" to continue the current test.
