Remote elevation measurement(REM)
This feature measures the elevation of a point where a prism can not be placed directly.The mesurement is extended along the plumb line while the elevation is continuously displayde.

Missing line measur measurement(MLM)
Multiple lines can be drawnbetween;
‧the first point and the last point;
‧ the last 2 points.
Horizontal distance,difference in height and slope distance is calculated.Coordinate file data and manual input data are available for further use.

Plane offset measurement
Coordinates are calculated for points where direct measurements to a prism can not be taken,for example point-measurements on a wall or plane.Three random points(P1,P2,P3)on the plane will be measured first to determine the measured plane and their angles and distances are temporarily stored,Then sight the unknow point on the plane and the instument calculates and displays coordinates and distance values of desired point

Z coordinate of occupied point(benchmark elevation)
The Z-coordinate and direction angle of the instrument is calculated and reset by measuring Z-coordinates of known pointa(Max.10 points).

Area cakulation
Area is calculated using measured data or file data (Coordinate data).

Point-to-line measurement
Create a new coordinate by measuring to two points.The first point becomes the origin and the secound point becomes the Naxis direction.

Roads
Defining complete roads with the use of lines, curves,spirals and points and stake out roads at each interval with optional offsets to right and left.
