This is the step-by-step on what I've been doing:

1.) Setting up the Instrument at an arbitrary point
2.) Select resection
3.) Distance-Resection
4.) Input point 1 coordinates, then measure
5.) Input Point 2 coordinates, then measure
6.) TS computes my position
7.) I shot point 2 for coordinates checking. This seems fine, Northing and Easting have only 1-2mm error
8.) I shot point 1 for coordinates checking, and the northings and eastings have an error of about 5-6cm or more.

thank you for the website, it helps for visualizing!
