Choosing A Measurement Reference - General LDM60 User Manual

CHOOSING A MEASUREMENT REFERENCE

The LDM60 can reference its measurements from the front edge
of the meter or the rear edge.
For most distance measurements, choosing the rear edge as the
reference produces more-accurate readings. Doing so allows you
to hold the bottom of the meter horizontally against one wall of a
room, or vertically against the floor, and send the laser beam out
the top of the unit toward the opposite wall or the ceiling.
However, for continuous distance (tracking) measurements (see
p. 15), using the front of the meter as the reference produces
more-accurate readings. In tracking mode, you typically walk the
meter back from a wall to a distance specified on a blueprint. In
this case, what you want to measure is the distance to the wall
from the top of the meter.
The button on the front panel lets you select the front or the
rear edge of the meter as the measurement reference. The two
small icons shown in Fig. 3 are the corresponding display
indications.
When the meter is powered off and on again, the measurement
reference automatically resets to the default: the rear of the
meter.
