Setting-Out Measurement; Using The Guide Light - Sokkia SRX1 Operator's Manual

17.SETTING-OUT MEASUREMENT

Setting-out measurement is used to set out the required point.
The difference between the previously input data to the instrument (the setting-out data) and the
measured value can be displayed by measuring the horizontal angle, distance or coordinates of the
sighted point.
The horizontal angle difference distance difference, and coordinate difference are calculated and
displayed using the following formulae.
Horizontal difference
Displayed value (angle)
Displayed value (distance) = measured horizontal distance x tan (horizontal angle of setting out data
Slope distance difference
Displayed value (slope distance) * = measured slope distance - slope distance setting-out data
* Horizontal distance or height difference can be input in the above formula.
Coordinate difference
Displayed value (coordinates)* measured N setting-out coordinates - N coordinates of setting-out data
* E or Z coordinates can be input in the above formula
Height difference (REM setting out measurement)
Displayed value (height) = measured REM data - REM data of setting out data
• Setting out data can be input in various modes: slope distance, horizontal distance, height
difference, coordinates and REM measurement.
• It is possible to allocate softkeys in the Setting-out measurement menu to suit various applications
and the ways that different operators handle the instrument.

Using the Guide Light

When the guide light is set to ON, the flashing speed of the light indicates the status of the SRX and
can be known when the user is located at a distance from the instrument. Also, the flashing colors
relative to the target indicate the direction of the instrument and allow the user to reposition the target.
