2. FEATURES
· HOlizontal angle, zenith angle, slope distance, horizontal
distance, height difference, N- and E-coordinates are displayed
by key operation.
· Horizontal distance between two prism points and remote
measurement of objects above and below a prism point are
automatically calculated. A stake-out function by bearing and
distance and N- and E-coordinates is standard.
· Self-diagnostic function. If, for any reason, the SET3 is not
functioning correctly during use, an error code is displayed.
· Angle lesolution can be set to 1" or 5".
· The tilt angle of the vertical axis can be measured by the
intemal sensor and displayed. By referring to the display, the
SET3 can be leveled. The zenith angle is automatically com-
pensated by the. ti It sensor and the compensated angle dis-
played.
· Hmizontal circle can be set to zero in any direction.
· The SET3 automatically switches off 30 minutes after the last
operation to save battery power,
· A RS-232C data-out connector is standard.
