Can someone help with the adjusted elevation and loop misclosure?

Answer 1

No loop misclosure occurred. So, no need to adjust elevations.

Arithmatic Check: Difference EBS & EFS - difference of = Worst Elevahon & lastelevation 17.26-17-23 . 10-9.97. 0.03 = 0.03. . So, no loop chi misclosure occured.com loop closed perfectly. So No need of adjusting elevations. If you find misclosure, then divide that to the rest of Observations made.. If you find elevations with rise and fall method, then check is, Differenæof EBS difference of difference of frost s = 3 Rise 's and last elevation. & EFS number & I Fall
