Setting A Direction Angle For Backsight Orientation - Topcon GTS-600 Series Instruction Manual

4.1 Setting a Direction Angle for Backsight Orientation

(Entering the instrument abd backsight coordinate values)
This program uses the input coordinate values of the occupied point, (instrument), and backsight point
to compute the backsight orientation direction angle.
The occupied coordinate input display appears as (BS:M-POINT). The backsight input display appears
as (BS:T-POINT). After the coordinate values are entered for both points, the instrument computes the
backsight direction angle for orientation. Only the occupied coordinate values are stored in memory if
the option is selected to (ON) in the Parameter Modes option. See Chapter 7 "PARAMETERS
SETTING MODE" . The program does not store the backsight coordinate values in memory.
