LDM will chirp, and the distance to the target—in the default distance unit of feet
with decimal fraction—will appear on the bottom line of the display.
To temporarily change the distance measurement unit, follow the instructions on
p. 10. Figure 4 is a screen shot of a measurement of
5 feet, 1 and 15/16 inches.

In direct distance measurement mode, you can display up to
three consecutive measurements in the order in which they
were made. Fig. 5 is a screen shot which shows the values
of three direct distance measurements made in top-to-
bottom order.

Continuous Distance Measurement
(Distance Tracking)
This operating mode is ideal for transferring measurements
from construction plans or blueprints. In practice, you walk the LDM back from a
wall a specified distance while the unit tracks its own position by measuring the
distance to the wall twice per second. As you make these dynamic measurements
and you close in on the specified distance, the LDM takes note of the closest and
farthest you have been from the wall and displays these minimum and maximum
distances along with the final distance.
Before entering continuous distance measurement mode, be sure to temporarily
change the measurement reference from the bottom of the housing to the top by
briefly pressing the
top against the wall. Then, after making sure that the laser is on, press the
button and back away from the wall while continuing to point the laser at the wall.
Initially (until the LDM reaches its minimum measurement distance of several
inches from the wall), the display will show an Error 261 message. Once the
minimum measurement threshold is passed, the LDM will begin to measure the
distance from to the wall twice per second. The measurements, accompanied by
chirps twice per second, will be shown and continuously updated on the bottom
line of the display. At the same time, the second and third display lines continuously
update the LDM's minimum and maximum distance from the wall during this
measurement session.
