Once onboarding is complete, the Sutro will immediately take a reading, which could take up to one hour.
After that, the Sutro takes three readings per day scheduled at 8am, 4pm, and midnight PST.

The readings must be 4 hours apart to allow the chemical additions to take full effect, but you can adjust them any way you'd like as long as they meet that requirement.
