The Measurement Signal Stops Rising During a Test

Connect the Vector to the Vector Interface app to inspect the cause.

Solutions

1. Check the output scaling is suitable for the material and test.

   Vector outputs the measurement as an analogue voltage via a BNC connection. Check the following attributes:

   • Check the scale of the Vector analogue output matches the signal input of the test frame.

     See section Scaling the Analogue Output Signal for more information on setting the analogue output to nominal values.

   • Ensure the range encompasses the expected minimum and maximum strain for the intended material and test.

     See section Scaling the Analogue Output Signal for more information.

     • Ensure the range includes a 20% margin on both the maximum and minimum.

     • Ensure the range does not vastly exceed the expected minimum and maximum strain for the intended material and test.

2. Check the specimen is not slipping in the grips.
