CMP6-L, CMP11-L, and CMP21-L Pyranometers
7. Installation
7.1 Mounting to a Tripod or Tower
Tools required for installation on a tripod or tower:
Small and medium Phillips screwdrivers
5/16”, 1/2” open end wrenches
5/32” Allen wrench
Tape measure
UV-resistant wire ties
Side-cut pliers
Compass
Step ladder
The pyranometers include a bubble level and two leveling screws, which allow
them to be leveled horizontally without using a leveling base. They mount to a
mast, crossarm, or pole (1.0 in. to 2.1 in. outer diameter) via the CM245
Mounting Stand.
If using a CFV3 Ventilation Unit, a different mounting stand, the NOTE
27084, is required. Refer to Appendix A, CVF3
Heater/Ventilator, for more information.
The CM245 includes slots that allow it to be adjusted to any angle from
horizontal to vertical. If mounting the pyranometer at an angle, ensure that the
crossarm is leveled horizontally before placing the bracket at its proper angle.
Angle positions are included on the bracket label (see FIGURE 7-1 and
FIGURE 7-2).
