Coord.z - Titan TTS2 Manual

3) Get the coordinates by the same way of the "Step-1", then
press [ENT] to enter the interface of "MLM
(A-B,A-C)-Result";
The result displayed is the measurement from first point to
second point; If you press [Next P], you will repeat the operations of
"MLM (A-B,A-C)-Step2"and "MLM (A-B, A-C)-Result",and can get
the measurement result of first point and other point;
As to "MLM(A-B,B-C)" , it's calculation of start point is
different, which is the previous of the measure point, but the other
operation are same as "MLM(A-B,A-C)";

9.4.4 Coord.Z

This function is that use the measured data of known points to
calculate the Z coordinate of station and reset Z coordinate.
You can get the coordinate data of known points from coordinate
data or by keyboard. The operations as follows:
1) Set station, select "Setup STA"；
Here, you can press [Coord.] to input station point, or press
[List] to retrieve coordinate from known files.
2) Setup datum mark. You can press [2] (Datum mark) to enter
the interface of "Coord.Z-No.1";
Press [Input] to input the name, coordinates and target height of
the first point, whose input method is same as
82
