To insert or remove the wires you must press down on the tab on top of the connector using a small screwdriver or blunt pencil.

Example plot of Percent Field Capacity vs. time as viewed using menu option 12.

The x-axis on this plot represents 6-days (note, the x-axis is mislabeled). Data are for a large sunflower growing in a 1- gallon pot. In this case we are getting 3 or 4 irrigations every six days, or about once every 1.5 days.
