1. Set the 'Calibration Integration Time' equal to the OFF position Integration time
2. Set the 'Interval' to be 15-20min by estimating the time for 1 scan. (e.g., if Total time per one map = 60min and the number of scans = 60, the time for 1 scan = 1min. Thus, 15-20min corresponds to 15-20 scans. So input 15-20 as 'Interval')
3. You can find appropriate OFF position Integration time and Calibration interval from HERE.
