on the left side of the device or mark with the marker button (3) the
centre point (e.g. 2.000 m) of the overall length.
The measured distances are always calculated from that edge of the
housing with the reference arrow (D) or (I). At any time you can change
between the left and the right edge of the device resp. switch over the
reference point. In this case the width of the device will be subtracted or
added to the result (only in the measuring mode „Start“, if the value
does not flash).
Detecting several Measuring Points
Display:
Place the device on the right wall and press the button
(10) to
switch on. On the display the measuring value (H) flashes. Select the
desired measuring unit (see Switching over the measuring unit). Before
measuring, decide which point should serve as reference point (in the
example the “right edge“), by pressing the key
. On the display the
reference arrow (D) appears.
Roll the device over the distance to be measured up to the left side of
the wall. To achieve the overall length the width of the device has to be
