The CM225 Solar Sensor Mounting Stand is used to attach the CMP3-L to a
vertical pipe (1.0 – 2.1” OD) as shown in Figure 3-1. The CMP3-L includes a
base with two levelling screws, bubble level, and mounting screws.

Attach the CMP3-L to the CM225 as follows:

1. Loosely mount the pyranometer on the mounting arm. Do not fully tighten

the two mounting screws.

2. Turn the levelling screws as required to bring the bubble of the spirit level

within the ring.

3. Tighten the mounting screws to secure the assembly in its final position.

Check that the pyranometer is still correctly levelled and adjust as
necessary.

4. Attach the white plastic sun screen to the pyranometer.
