§6.1.3 Field Operation Notes
1)Static mode of KOLIDA K20s receiver can be set in EGStar software or other software (Such
as SurvX, Field Genius or SurvCE), also can be performed by receiver keypad.
2)Set up a tripod on the control point, leveling and centering strictly on the measuring point.
3)Measure the instrument height three times, the difference of the results shall not be more than
3 mm, and average the results. The instrument height should be measured from the center of the
control point to the mark line on the instrument.(Refer to §3.4)
4)Record instrument number, point name, instrument height, and start time.
