What is the settable range of measurement interval in oneshot mode?
Long interval would be no problem. As for short interval, 0 power down time is OK in theory, but it might be delaied owing to variation of clock etch. In order to avoide it, we recommed you to confirm whether data is updated by interrupt setup, then acquire data. You can confirm this by Bit2 (Data Ready) of Register CTRL_REG1.
