  • Page 19: Calibrating The Board

    Chapter 4 Calibrating the Board You should calibrate the board using the InstaCal utility software after the board has fully warmed up. The recommended warm-up time is 15 minutes. For best results, calibrate the board immediately before use. The high resolution analog components on the board are temperature-sensitive, so calibrating the board before use ensures that your board is operating with the optimum calibration values.
