7.1
Siting
Mount the pyranometer such that no shadows or reflections are cast on it by the
tripod/tower or other sensors, and point the cable towards the nearest magnetic
pole. For example, in the Northern Hemisphere, point the cable toward the
North Pole.
Mounting height is not critical for the accuracy of the measurement. However,
pyranometers mounted at heights of 3 m or less are easier to level and clean.

Required Tools
Tools required for installation on a tripod or tower:
Small and medium Phillips screwdrivers
1/2 in open end wrench for CM225 or 015ARM
Tape measure
UV-resistant cable ties
Side-cut pliers
Compass
Step ladder

Mounting Procedure
These sensors can be mounted either on a CM225 universal sensor plate or an
AL-120 combined level and sensor plate. The AL-120 is mounted on the arm
in the same way as the CM225 and the sensor is mounted to the levelling plate
as also shown below. With the AL-120 the levelling plate is mounted on the
stand with the spring underneath it.
Never mount the CM225 directly to a vertical pipe. Instead,
mount the CM225 to a crossarm. This avoids reflections
from the vertical pipe onto the sensor.
1. Mount the crossarm to the tripod or tower if using a CM225.
