LMS Vibration Control: "Transducer on Channel Input2 is too sensitive for current reference profile"

Creator

I am getting a message in LMS Test.Lab Vibration Control Sine: "Transducer on Channel Input2 is too sensitive for current reference profile". I cannot proceed with my test.

 

I am certain my profile is correct. What should i do?

Is it possible that your DAC will be maxed out during your profile with this transducer?  The max DAC output is 10 Volts.

 

For example, if a profile has a max acceleration of 10 g;

 

(10 mV / g accel) * 10 g = 100 mV

(100 mV / g accel) * 10 g = 1 V

(1000 mV / g accel) * 10 g = 10 V

 

The suggestion is to use a less sensitive accelerometer.  In the example above 1000 mV / g would cause the warning but 100 mV/g and 10 mV/g would not.

 

You can also reach out the GTAC support team in North America via the 1-800-955-0000 number in the US or Canada or reach out to us via email.

Went to my calibration lab and got a 10 mV/g accelerometer to replace my 100 mV/g accelerometer.  Everything is working properly now.  Thanks.
