Questions and answers
my south N3 Shows angle error 2 pop up message how can that be corrected or adjusted in the lab
To correct or adjust the angle error 2 (2C) on a South N3 Series Total Station, follow these steps:
1. Inspection
- Set object A at a far distance at the same height as the instrument.
- Level the instrument and turn on the power.
- Sight object A in the horizontal left position and read the horizontal angle (HA).
- Rotate the telescope to the horizontal right position and read the HA again.
- Calculate 2C using the formula: 2C = HL - HR ± 180°.
- If the value exceeds the acceptable range (e.g., ±20”), adjustment is required.
2. Adjustment
- Use the tangent screw to adjust the horizontal angle to the correct reading.
- Eliminate the observed error by fine-tuning the settings.
- Repeat the inspection steps to verify the adjustment.
This process ensures that the perpendicularity between the sight of view and the horizontal axis is correctly aligned.
