about ±10°. Read the face left angle Vl and face right angle Vr.
(3) Calculate the index error according to the formula below:
i = ( Vl+Vr-360°)/2
(4)If I<10”, no adjustment is necessary, or you have to adjust it .
2) Adjustment by program:
Set-up the instrument on tripod or adjustment platform, and leveling accurately.
