18. MISSING LINE MEASUREMENT
Missing line measurement is used to measure the slope distance, horizontal distance, and horizontal angle to a target from the target which is the reference (starting point) without moving the instrument.
•It is possible to change the last measured point to the next starting position.
•Measurement result can be displayed as the gradient between two points.

18.1Measuring the Distance between 2 or more Points
PROCEDURE
1.Sight the target of the starting
position, and press 
in the first page of Meas mode to begin
measurement.
The measured values are displayed.
Press 
to stop measurement.
2.Sight the second target and press
in the third page of Meas mode to begin observation.
The following values are displayed:
S:Slope distance of the starting position and 2nd target.
H:Horizontal distance of the starting position and 2nd position.
V:Height difference of the starting position and 2nd target.

3.Sight the next target and press
to begin observation. Slope distance, horizontal distance and
height difference between multiple points and the starting position can be measured this way.
•When 
is pressed, the distance between two points (S)
is displayed as the gradient between two points.
•Press 
to re-observe the starting position. Sight the
starting position and press
.
•When 
is pressed, the last target measured becomes the
new starting position to perform missing line measurement of the next target.
