Measuring with the aid of a target object

Measuring distances, continued
A board, bricks or other suitable objects can be
used as the target when taking a measurement
from an outside edge (e.g. outside walls of
houses, perimeter fences etc).
4. Working with the PD 20
Measuring using the self-timer
Measuring distances, continued
e.g. for measuring from inaccessible positions
The use of an extension rod can be of great
assistance for measuring with the PD 20 from
points where access is difficult or even
impossible to reach without some form of aid.
One of the two threaded bushings (1/4" tripod
thread) on the PD 20 can be used for attaching
an extension rod.
When an extension rod is used, the delay
between pressing the “measure” button and the
moment at which the measurement is taken can
be set with the assistance of the self-timer
(delay) function. Use the dELAY menu to set the
delay.
