CM106B Tripod 1. 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 2. Cautionary Statements • READ AND UNDERSTAND the Precautions section at the front of this manual.
CM106B Tripod • 3. WARNING — For installations where soil structure is questionable or the tripod may experience high wind loads, concrete footings for the tripod feet and guy anchors should be considered. Initial Inspection 3.1 Inspect Packaging Upon receiving the CM106B, inspect the packaging and contents for damage. Claims for shipping damage must be filed with the shipping company.

CM106B Tripod 6. Installation 6.1 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 to one of the three leg mount positions on the tripod, facing the desired direction.
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. Two additional holes make it possible for the extension to extend 8 in. or 12 in., or 20 in., 24 in., or 28 in. above the mast depending on which end is inserted in the mast.
CM106B Tripod Preset at Factory Mast Bolts Tab 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. Slide the mast into the tripod base, making sure that it extends below the lower bolts and rests on the tabs. Tighten the six bolts to secure the mast. Plumb the tripod by adjusting the northeast and south facing legs.
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. Guy Collar Guy Wire Guy Bracket FIGURE 6-5. Guy collar On the end of each guy line is a case and hardware to attach to the turnbuckles.
CM106B Tripod Clamp Nut FIGURE 6-6.
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. For questionable situations, additional stakes (pn 17049) or even concrete footings for the tripod feet and guy anchors should be considered. FIGURE 6-7.
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. Attach the other end of the ground wire to the lug on the tripod base as shown in FIGURE 6-8.
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. Mount the lightning rod and clamp to the tripod mast with pointed tip up, and notch at bottom (FIGURE 6-9). Lightning Rod Clamp Mast FIGURE 6-9.
CM106B Tripod 6.1.6 Crossarm Attachment Attach the CM202 (0.6 m, 2 ft), CM204 (1.2 m, 4 ft), or CM206 (1.8 m, 6 ft) crossarm to the tripod mast as shown in FIGURE 6-10. For wind sensors, the crossarm should be approximately 103 in. above the ground for a 3 m mounting height, or 64 in. for a 2 m mounting height. Typically the crossarm is oriented East/West for wind sensors, North/South for pyranometers. CM200 Series Crossarm Tripod Mast FIGURE 6-10. CM204 Crossarm 6.1.
CM106B Tripod 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. of insulation from each end of the wire. Insert wire ends into the ground lugs and tighten. Lock Washers Nuts U-Bolt MM Bracket FIGURE 6-11. Enclosure with the –MM bracket 6.1.7.

CM106B Tripod 6.2 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 mm Nominal Pipe Size (inches) 1.5-in. U-bolt 1.0 – 1.5 25.4 – 38.1 ¾–1 2-in. U-bolt 1.3 – 2.1 33.0 – 53.3 1–1½ 2-in. U-bolt with plastic V-block 1.0 – 2.1 25.4 – 53.3 ¾–1½ Some of the brackets (for example, the CM210) include 1.5-in. and 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. CM216 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.
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). The CS300 pyranometer mounts to the CM225 via the 18356 leveling base.
CM106B Tripod 6.2.5 CM230 and CM230XL Adjustable Angle Mounting Kits 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. The CM230XL is similar to the CM230, but has a longer mounting arm (see FIGURE 6-17). Its longer length places the antenna or sensor away from the mast or pole. CM230 CM230XL FIGURE 6-17.
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.
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. To attach the radiation shield to a horizontal pipe, the U-bolt and plastic V-block must be moved to the other set of holes. FIGURE 6-19. R.M.
