Automatic grade setting
In order to obtain the accurate grade value, first perform the Automatic alignment, measure the
direction of the target, and then automatically set the grade.
For the Dual axes setting, specify the reference direction for the 1st axis.To prepare the instrument
for Automatic grade setting, X and Y axes must be roughly aligned to within 10° of the true axis
desired. This can be done by using the molded sights of top of the instrument housing.
Executing Automatic grade setting
Since the range over which the grade is set automatically is within about 10° of the width in the X
and Y directions of the instrument, place the instrument so as to be within that range. In addition,
since the Automatic grade setting range is ±5°, use the instrument within that range.
