3. Using a diopter in combination with a solar compass, install and orient the crossarm on the
tripod or the mast. If installing the mounting bracket on a vertical pole, ensure the pole is
truly vertical.
4. Secure the mounting bracket to the crossarm or vertical pole using the hardware included
with the mounting bracket. The CM255 uses one U-bolt, nuts, flat washers, and lock
washers to mount the bracket, as shown in the following figure.
5. For the CM255LS bracket, use the two set screws to secure the bracket to the crossarm or
pole as shown in the following figure. For pyranometers mounted horizontally, ensure the
mounting bracket is horizontal in two dimensions. For pyranometers mounted at an angle,
set the mounting bracket angle to the desired angle prior to tightening the mounting
hardware.
