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).
