Missing Line Measurement; Measuring The Distance Between 2 Or More Points - Sokkia iM-50 Series Operator's Manual

21.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.

21.1 Measuring the Distance between 2 or more Points

The distance between two or more points can either be measured by observing the targets in question or
calculating from input coordinates. A combination of these two methods (e.g. observing the 1st target and
inputting 2nd target coordinates) is also possible.
PROCEDURE Measuring using observation
1. In the third page of OBS mode screen, press [MLM], then
select "MLM".
2. Sight the 1st target and press [MEAS].
• If the distance measurement data remains, the last
measured distance data is set as the starting point, and the
screen in step 3 is displayed.
• The tilt screen is displayed if the instrument is out of level.
Level the instrument.
"7.2 Levelling"
3. Sight the second target and press [MLM] to begin
observation.
