You must have registered and installed the sensor before pouring. It's important to take note of the exact date and time at which the sensor was covered with concrete. Accurate start times increase the precision of concrete strength measurements.
To record when the sensor was covered with concrete in the web platform:
Step 1: Select the sensor previously registered on the platform. Then, click Calculate Strength on the bottom-left side of the graph.
Step 2: Select in the calendar the day and time. You can also specify the milestone(s) for a sensor, to receive a notification when that strength is reached.
To record when the sensor was covered with concrete in the app:
Select the correct pour and 'select pour time' on the target sensor
