Suggested Mounting: Use 1/2 inch Stake Kit (Part # M-SKA). • Onset recommends that two people set up most tripod systems. Some assemblies are heavy and are easier to handle with two people. •... -
Page 6: Mounting
If you will be mounting PAR, wind speed, or rain gauge sensors, be sure that you install the mast vertically (using Mast Level, Part # M-MLA). • Use the Guy Wire Kit (Onset Part # M-GWA) to stabilize a tall mast. Use 1/2 inch stakes (Part # M- SKA) to secure the guy wires. •... -

Page 11: Task 1: Assemble Tripod
Onset Computer Corp. Task 1: Assemble Tripod There are two types of tripods available: the 2 meter (Part # M-TPB) and 3 meter (Part # M-TPA). The 2 meter instructions begin on this page. The 3 meter instructions begin on page 10. - Page 12 Onset Computer Corp. Figure 2: Nut and bolt assembly 3. Take one of the nut and bolt assemblies and insert it through a tri-clamp hole with the bolt head facing outward. 4. Loosely install a nut on the bolt to the inside of the tri-clamp.
- Page 13 Onset Computer Corp. 7. Tighten the tri-clamp bolts by hand so that the mast is temporarily locked into position. Note: The lower mast can rest on the ground at this time. You will adjust the height of the lower mast later.
- Page 14 Onset Computer Corp. 3 meter tripod/lower mast assembly instructions: This is an example of a typical 3 meter tripod assembly with a mast-mounted Rain Gauge sensor. Figure 5: 3 meter tri-pod 1. Using 5/16 inch nuts, attach the three anchor plates to the three tripod foot brackets, with the large holes to the outside.
- Page 15 Onset Computer Corp. Figure 6: 3 meter lower tripod 3. Open the tripod and place it in an upright position. 4. Unfold the leg brace assembly and place the assembly flat on the ground. Figure 7: 3 meter tripod leg brace...
- Page 16 Onset Computer Corp. 5. Attach each of the three inner legs to each of the leg U-bolt assemblies (5/16-18 inch) using the inner stud of the U-bolt. To attach each inner leg, remove the nut from the inner stud, slide the leg over the stud, and then tighten the nut finger.
- Page 17 Onset Computer Corp. 8. When the tripod is oriented on the site, secure one of the three tripod legs to its mounting location and tighten the U-bolts on this leg. 9. Adjust the second leg to level in one direction and secure this leg.

Page 18: Task 2: Install Grounding Kit
Onset Computer Corp. Task 2: Install Grounding Kit This section explains how to install the grounding rod from the Grounding Kit (Part # M-GKA) and attach it to the lower mast of either the 2 meter and 3 meter tripods. -
Page 19: Task 3: Temporarily Install Upper Mast (Optional)
Onset Computer Corp. Task 3: Temporarily Install Upper Mast (Optional) This section explains how to temporarily attach the upper mast to the tripod base. This allows you to easily work on the upper mast while it is resting on the base of the tripod. -
Page 20: Task 4: Mount Cross Arm (Optional)
Task 4: Mount Cross Arm (Optional) Onset recommends that you use the cross arm to mount the Wind Speed or Wind Speed/Direction sensor because it keeps this sensor away from other sensors that could cause wind turbulence or wind shadows. -
Page 21: Task 5: Mount Upper Mast To Lower Mast
Onset Computer Corp. Task 5: Mount Upper Mast to Lower Mast NOTE: Onset recommends that two people work together to attach the upper mast to the lower mast. 1. Lightly grease the creased (upper) end of the lower mast. 2. While holding the upper mast securely, cut the cable ties that were temporarily holding the upper mast to the lower mast. -
Page 22: Task 6: Mount Logger To Upper Mast
Onset Computer Corp. Task 6: Mount Logger to Upper Mast 1. Using the two 1-5/8 inch U-bolt assemblies provided, mount the logger enclosure on the lower end of the upper mast in line with the upper mast dimple. The lower housing U-bolt can be placed directly above the U-bolt holding the mast pieces together. -
Page 23: Task 7: Install Guy Wire Kit (Optional)
Onset Computer Corp. Task 7: Install Guy Wire Kit (Optional) NOTE: If you are using the 2 meter tripod, you will need to attach the guy wires to three 1/2 inch stakes (Part # M-SKA), which should be spaced evenly around the tripod at a distance of 3 to 4 m (10 to 13 ft) from the mast. - Page 24 Onset Computer Corp. Figure 17: Guying to 3 Meter tripod feet 4. Cut the guy cable so that it can be put through the loose end of the turnbuckle and the wire clamp. Make sure the turnbuckle is extended as shown in the figures before feeding the cable through.

Page 25: Task 8: Position And Level Sensors
Onset Computer Corp. Task 8: Position and Level Sensors Once the upper mast is locked in place and secured, position the sensors at the correct heights and check that the Rainfall sensor and PAR sensors are level. See the sensor manuals for more details. - Page 26 Onset Computer Corp. 7. Seal logger enclosure (HOBO Weather Station Only). This step is especially important if the system is located in a wet environment. Once you verify that the cables are secured in the inside of the logger box, take all the cables and push them over to one side of the logger enclosure opening.
