Inspection

1. After leveling the instrument, collimate at any

target A in HL. Record the value as L.

2. Rotate the EDM and aim at the target A in HR.

Record the value as R.

3. If the vertical 0°in zenith, I =(L + R - 360°)/2. If

the vertical 0 in horizon, I= (L + R - 180°)/2 or (L +

R - 540°)/2.

5. If |i| ≥10”, it need to reset the Vertical 0.

Adjustment

1. Aim at target A in same height with the

instrument in HL.

2. Aim at the same target A on HR.

3. After setting the angle in both HL and HR, it will

display the index difference, press [Reset] to

confirm the adjustment.

4. Repeat the inspection steps to check the

Index Difference (i angle). If the difference still

cannot meet the requirement, please check

whether the steps you did are correct. Then reset

again.

5. If the Index Difference still fails to meet the

requirement after repeated operation, the

instrument should be returned to our authorize

service center for inspection and repair.

Note: The value of vertical angle is not adjusted and

compensated, just for a reference in adjustment.
