in the summary line between the stake out point (first a and then b) and the instrument (rear refer- ence).
If the DISTO™ is then moved slowly along the stake out line the displayed distance decreases. The instru- ment starts to beep at a distance of 0.1m from the next stake out point.
a
The arrows in the display 
bb
indicate in which direc- tion the DISTO™ needs to be moved in order to achieve the defined distance (either a or b). As soon as the stake out point is reached the beep changes and the intermediate line starts to flash.
The function can be stopped at any time by pressing the 
button.
Indirect measurement
The instrument can calculate distances using Pythag- oras’ theorem.
This method is especially helpful if the distance to be measured is difficult to reach.
)Make sure you adhere to the prescribed sequence of measurement:
•All target points must be in a horizontal or vertical plane.
•The best results are achieved when the instru- ment is rotated about a fixed point (e.g. with the
positioning bracket fully folded out and the instrument placed on a wall).
•The minimum/maximum function can be used - see explanation in "Measuring
)Make sure that the first measurement and the distance to be measured are at right angles. Use the Minimum/maximum function, as explained in "Measuring
Indirect measurement - determining a dis- tance using 2 auxilliary measurements
See figure {M}
e.g. for measuring building heights or widths. It is helpful to use a tripod when measuring heights that require the measurement of two or three measure- ments.
Press this button once, the display shows 
. The laser is switched on.
Aim at the upper point (1) and trigger the measurement. After the first measurement the value is adopted. Keep the instrument as horizontal as possible.
