ADIS IMUs and storage temperature

Hello,

We are going to evaluate your ADIS16445 and ADIS16485 IMUs. One of our requirements is that IMU must have at least -55 degrees storage temperature. There is -65 degrees storage temperature mentioned in your datasheet but with a note: "Extended exposure to temperatures outside the specified temperature range of −40°C to +105°C can adversely affect the accuracy of the factory calibration. For best accuracy, store the parts within the specified operating range of −40°C to +105°C." Now the question is what does it mean extended exposure? It is one hour,one day or one week? We need to do a test where IMU will be exposed for at least 3 hours to -55 degrees, then it is heated to -40 degrees and then we test the performance. Can 3 hours exposure affect the accuracy of the calibration?

 

Thanks
