Hi
I am doing calibration on accelerometer of analog providing dual axis acceleration to measure tilt angle of sensor.
Based on spec sheet from analog, the sensor should be in linear equation V=Ka+B
V=Voltage output
K=Linear sensitivity
a=acceleration of axis
B=Bias voltage.
However, i turn the sensor with known angle, i get the voltage. Plotting the graph of Voltage versus acceleration, i am not able to get linear curve of V=Ka +B, but nonlinear graph.
How can i determine the non linear error and resolution from the newly plotted graph in labview?i have collected data. and i wish to do regression analysis. How i can do it in labview?
After getting the nonlinear regression, how can i know my new model (new equation) has improved error and resolution?
Can someone ple help
your kindness is Much appreciated
Regards
