This proves itself out. Rotate the pole 360 deg while staying in the same location and watch your bubble, this will be your visual, let you see for yourself the quality of the calibration.
I screw the top of my prism pole to a point that alows the rod to hang freely and rotate any direction. I wait for it to stop swinging so its plum to ground. If bubble is off i adjust. Maybe im wrong but this video seems too much
This method works but is a lot more convoluted than necessary. Bubble vials are self checking, you can check/fix their calibration without other accessories like the spirit level
yeah but this actually takes time out of it if the bubble vial is not in the same plane as the pole. you have to have a guaranteed starting point. I received a new fixed height tripod the spirit level said was out of level when the bubble level said it was. use the spirit level then adjust the bubble to it. after a few adjustments to the bubble level everything talked. I thought the same thing you just said but after chasing my tail for about 10 minutes i realized the pole and the bubble level were not on the same plane. the only way to do this is with a spirit level.
My Land was previously surveyed by someone who used a plumb bob too. It turned out that day it was really windy. :) JK... I do enjoy using a PB. I have worked with many old time surveyors that would fire anyone who didn't keep a consistent bob.
Thank you!! Very helpful tip with rubber band!!
Thank you SO much. Wow. Awesome video.
nice TIP man thanks for sharing ...thumbs up
sure thing
Nice Stan
What if your spirit level is out of adjustment?
Wilson The Grapefruit just check the spirit level bubble
You can do it without spirit level. Bubble should remain centered 360 deg. If it is, you're good.

You come with a second spirit level to level the first spirit level to level the pogo if that makes sense 😂

how to understand totalstation calibration right or wrong
Close transit to within tolerances
The joys of learning how to become a good surveyor. Always good to know how to maintain your equipment.
Thanks a lot for sharing this useful video
No prob
Why are you adding the piece of rubber band?
Paul Davidson, we use the rubber band as a pivot point and to add resistance against the screws. It makes it much easier to calibrate the bubble.
I will give it a try. Thanks for the video it was very helpful.
Nice video but for verticallity of rod you rod is big at top and thin at bottom how u check
Send over an image of the prism pole and we can help.
