Campbell Scientific CS110 Electric Field Meter - Manual (Page 74)

Appendix G. CS110 2 Meter CM10 Tripod Site
Installation of the Tripod_CS110 Site:
Drive the ground rod into the ground where the center of the tripod is to be
placed.
Extend the tripod legs so the far end of the sliding clamp is 56 inches (142 cm)
from the mast end of the pipe. Extending the legs as described above puts the
feet on a circle with a radius of approximately 77 inches (196 cm) from the
center of the tripod to the outside edge of the pivoting feet. The distance from
the top of the top collar to the ground will be approximately 40 inches (102
cm). Locate the center of the tripod above the ground rod with one leg of the
tripod pointing toward the equator. Level the tripod by removing or adding
small amounts of gravel under the feet as needed.
Apply Teflon tape to both ends of the 1 ¼ inch (3.175 cm) outside diameter
mast.
Attach the cap to the top of the mast.
Attach the CS110 mounting bracket to the mast with the top of the bracket
about 9¼ inches (23.5 cm) below the top of the cap on the mast but don’t
tighten bolts very tight as it will likely need to be rotated and either raised or
lowered slightly.
Mount the completed mast on the tripod.
Adjust the CS110 mounting bracket so the top of the mounting bracket is
approximately 90 inches (229 cm) above the ground and between the two legs
opposite the equator still leaving the bolts not too tight yet. Mount the CS110
on the mounting bracket. The field meter should now be facing away from the
equator with the face of the stator 78 ¾ inches or 200 cm above the ground.
Tighten the mounting bolts. See Figure G-2.
