The Restore Defaults command requires approximately 1.8 seconds. Therefore, the
application program should wait the maximum amount of time and be sure it receives the
command response before issuing another command to the controller.
Note: After you issue a Restore Defaults command, you must recalibrate your sensor
using a 2-point calibration.
