    Hi,

            We have purchased 10 BMi088 sensors for our application.  We have evaluted Bias inatability of these 10 BMI088 sensors using Allan Var method at constant temperature of 25 Deg C using thermal chamber.

    But the bias instability of all sensors is above 4 deg/hour, only one sensor bias stability out of 10 sensors resulted in closer to 2 deg/hour.

    Is every BMI088 sensor factory tested and calibrated in production?

    Bias instablity is mentioned in flyer document as 2 deg/hour but Allan Plot is not printed in flyer document! why?

    Please clarify above all queries.

    Regards,

    Venkat

    Hi venkat57,

    Thanks for your inquiry.
    We have the following questions about your Allan analysis of variance:
    What is the testing environment for conducting Allan analysis of variance?
    Does BMI088 remain stationary during the testing process? Is there any interference around?
    What are the test results for the x, y, and z axes?
