Geonor Leveling

Tools

• Geonor brand torpedo Level
• Sledge Hammer

Supplies

• Shouldn't need any

May/June Procedure

• Choose a sunny / not raining day for this
• Carefully remove the outer case / orifice. If it is wet, wipe it down or shake a bit of water off as best you're able before attempting removal. We need to keep water off the sensitive electronics inside the instrument.
  • When lifting it off it's easy for the quick release clamps to get hung up on instrument. To reduce the frequency of this happening, wedge the clips on the outside of the metal flipper tab that is used to secure in place (easier to see this in person of course or if I remember how to do photos on here I will add photos).
• With the lid off, loosen some (but you don't need to do all) of the tie downs that are secured to the fence posts.
  • I can tell your right off that historically the South and West side tie downs are mainly used to keep things vertical so start by loosening them. It's possible you'll need to take up a bit of slack at the end with the others but I'm guessing not for now.
• Once the ones you'll be working are loose, put the level up top. I like to start with North-South level direction.
• Add tension to the tie downs unti the N-S level bubble is in the center. Do it in a couple clicks at a time on each tie down to the south so that they're all taking the load evenly.
• when N-S is level, take a picture for your records with your phone.
• Rotate the level 90 degrees and repeat in the east-west direction. Most likely you will just focus on tightening the West side.
• Once things are tight and level to the South and West, check on the North / East tie down and tighten a bit to remove any slack and put them in slight tension.
• Replace the orifice by first setting it on the SW side cross arm horizontal arm. Then once you are on the step ladder and inside the wind altar shield circle, lift it high and up over the geonor then down onto the main sensor body.
• Re clamp the three edge clamps.
• Done.

Fall Procedure

• Striking Similar with a notable couple differences.

• In the fall, use the sledge hammer to try pounding the green and white fence posts in a bit deeper. Final target height is all of the white plus a small bit of green above the ground surface (you can decide for yourself what is the actual ground surface). Only in the fall is the active layer deep enough to pound the posts in a bit further. In 2022 a few of the fence posts reached this final height.
• Okay, with that step out of the way, resume the spring procedure.
• Once the ones you'll be working are loose, put the level up top. I like to start with North-South level direction.
• Add tension to the tie downs unti the N-S level bubble is in the center. Do it in a couple clicks at a time on each tie down to the south so that they're all taking the load evenly.

• Pause here to replace the fluids in the geonor
