CM106B Tripod Introduction The CM106B is a general purpose tripod that can be used for mounting sensors, solar panels, antennas, and instrument enclosures. FIGURE 1-1 shows the CM106B being used in a typical weather station configuration. FIGURE 1-1. Typical tripod-based weather station...
Initial Inspection Inspect Packaging Upon receiving the CM106B, inspect the packaging and contents for damage. Claims for shipping damage must be filed with the shipping company. Locate the packing slip for the order and compare the items listed on the packing slip to the items that were actually shipped.

Section 6.1.7, Enclosure Attachment. The CM106B can be used for a variety of applications. For meteorological stations, sensors are mounted to the tripod using mounting brackets appropriate for the model of sensor.
CM106B Tripod Installation Tripod Installation 6.1.1 Tripod Base The tripod base has three independently adjustable legs allowing the tripod to be installed over non-level terrain. Prepare the area where the tripod will be installed. The tripod requires an area approximately 2.7 to 3.5 m (8.7 to 11.5 ft) in diameter. Natural vegetation and the ground surface should be disturbed as little as possible, but brush and tall weeds should be removed.
CM106B Tripod 6.1.1.1 Mounting on a Relatively Flat Area Loosen the tension bolt and extend each leg. With the legs extended, orient the tripod so that one of the legs points South (assuming the instrument enclosure with –MM Mast Mount bracket will face North). If the instrument enclosure has the –LM Leg Mount bracket, orient the tripod so the enclosure will mount...
CM106B Tripod 6.1.2 Mast The CM106B includes a mast extension that can be fully extended for a 3 m (10 ft) height, or partially extended for a 2.1 m (7 ft) height. Remove the bolts in the extension, align the holes in the insert with holes in the mast, and install the four bolts previously removed.
CM106B Tripod Preset at Factory Mast Bolts Preset at Factory FIGURE 6-4. Mast attachment to tripod base Loosen the six bolts on the tripod base. FIGURE 6-4 shows the location of four of these bolts. The remaining bolts are in the same position on the third tripod leg.
CM106B Tripod 6.1.3 Installing the Optional Guy Kit Part 29813, CM106B Guy Kit, can be ordered separately for areas that experience high wind speeds (Section 5, Specifications). Install the guy brackets to the mast as shown in FIGURE 6-5. Attach the three guy wires to the guy collar and slide the collar over the mast so that the collar butts against the brackets.
CM106B Tripod 6.1.4 Staking the Tripod Feet Six stakes are provided for securing the tripod feet to the ground. Drive two stakes through holes in each foot at an angle as shown in FIGURE 6-7. Stakes may not be adequate depending on soil structure, maximum wind speeds experienced at the site, mast height, or wind load from the instrumentation.
CM106B Tripod 6.1.5 Tripod Grounding Place the clamp over the ground rod and drive the rod (close to the center of the tripod) using a sledge hammer or fence post driver. Strip 1/2 in. of insulation from both ends of the black 4 AWG ground wire. Insert one end of the ground wire into the clamp and ground rod and tighten the bolt on the clamp.
CM106B Tripod Strip 1/2 in. of insulation from the ends of the green 12 AWG wire. Attach one end of the wire to the tripod ground lug, and the other end to the enclosure ground lug as shown in FIGURE 6-8.
6.1.7 Enclosure Attachment The ENC10/12, ENC12/14, ENC14/16, and ENC16/18 enclosures can be ordered with mounting brackets for the CM106B tripod. All enclosure models can be mounted to the tripod mast (above the legs) with the –MM Mast Mount bracket option. All enclosure models except the ENC16/18 can be mounted to the tripod base and leg with the –LM Leg Mount bracket option.
CM106B Tripod Install the U-bolts, flat washers, lock washers, and nuts (FIGURE 6-11). Tighten the nuts until the lock washers are compressed. Route the 14 AWG wire from the ground lug on the bottom side of the enclosure to the ground lug on the base of the tripod (FIGURE 6-8). Strip 1/2 in.
CM106B Tripod Remove the washers, nuts, and U-bolt from the U-bolt bracket. Install the bracket as shown in FIGURE 6-12 (top). Tighten the nuts on the U-bolt until the lock washers are compressed. Route the 14 AWG wire from the ground lug on the bottom side of the enclosure to the ground lug on the base of the tripod (FIGURE 6-8).
CM106B Tripod Mounting Brackets Mounting brackets covered in this section have U-bolts that attach to vertical and/or horizontal pipes with the following ranges of outside diameters: inches Nominal Pipe Size (inches) 1.5-in. U-bolt 1.0 – 1.5 25.4 – 38.1 ¾ – 1 2-in.
CM106B Tripod 6.2.2 CM216 Mast Mounting Kit The CM216 attaches to the top of the mast, and provides a 3/4-in. or 1-in. mounting pipe (1.05-in. or 1.32-in. OD) that extends 4 in. above the mast, as shown in FIGURE 6-14.
CM106B Tripod 6.2.3 CM220 Right Angle Mounting Kit The CM220 attaches a vertical pipe (1.0-in. to 1.5-in. OD) to the CM200-series crossarms or horizontal pipe (1.0-in. to 1.5-in. OD) as shown in FIGURE 6-15. CM220 CM220 FIGURE 6-15. CM220 Right Angle Mounting Kit...
CM106B Tripod 6.2.4 CM225 and 18098 Pyranometer Mounting Stand The CM225 is used to attach a pyranometer or quantum sensor to a horizontal pipe (1.0-in. to 2.1-in. OD) or vertical pole (1.0-in. to 2.1-in. OD). The LI200X pyranometer and LI190SB quantum sensor mount to the CM225 via the LI200S leveling base (see FIGURE 6-16).
CM106B Tripod 6.2.5 CM230 Adjustable Angle Mounting Kit The CM230 mounts an antenna (1.0-in. to 1.5-in. OD) to a mast or vertical pipe (1.3-in. to 2.1-in. OD) as shown in FIGURE 6-17. The bracket allows the antenna to be adjusted for different angles.
CM106B Tripod 6.2.6 CM235 Magnetic Mounting Stand The CM235 provides a 8.8 cm (3.5 in) square platform for mounting magnetic base antennas. The CM235 attaches to horizontal or vertical pipes (1.0-in. to 2.1-in. OD) as shown in FIGURE 6-18. FIGURE 6-18. CM235 Magnetic Mounting Stand...
CM106B Tripod 6.2.7 R.M. Young Gill Radiation Shields R.M. Young Gill Radiation Shields are used to house and attach temperature and relative humidity sensors to the tripod mast (1.0-in. to 2.1-in. OD) or crossarm as shown in FIGURE 6-19. Radiation shields ship with the U-bolt configured for attachment to a vertical pipe.
