Note
：
The constant of the instrument has been strictly set in the factory, so generally the user needs not to set this
item. If through strict measurement (ex. in standard baseline field and by special measuring organization) it is
necessary, the user can do that.
The
Additive Contant
is effective under
Prism mode
only (measuring distance with prism).
