Section 2 - Rain Gauge
Question 1
To secure the rain gauge
On the bottom of the sensor there are 4 holes. You can use those holes to screw the gauge into something. First remove the cover. You have to push in the tabs on the sides and then pull the cover off. There will be a teeter-totter the has a metal bar for an axis. Pull the metal bar out with a pliers. The teeter-totter can then be removed giving you access to the screw holes. Make sure that you do not screw them in too tight because that will cause your teeter-to malfunction. Then you can reinstall the teeter-totter making sure that it is put in the exactly the same way that it was taken out. Then put the cover back on.
