Measurements
The Meter measures the distance to a target, the area
bounded by two distances, or the volume in three
measurements. This manual identifies when a feature is
model-dependent. When not identified, all models include
the feature.
Single Distance Measurement
To measure distance:
1. Push
 to turn on the laser.
2. Push  again to make the distance measurement.
The measurement shows on the display.
Note
Measurement errors can occur if you point the
laser at colorless liquids, glass, Styrofoam,
semi-permeable surfaces, and high-gloss
surfaces. The measurement time increases
when you point the laser at dark surfaces.
A target plate is useful for long distance measurements if
the target reflectivity and illumination is a problem.
Minimum/Maximum Tracking
The tracking function measures the room diagonal
(maximum value) and the horizontal distance (minimum
value) from a stable measurement point. It also can find
the distance between objects. See Figure 10.
Min. Max.

To measure:
1. Push and hold  for 2 seconds.
 shows on the display to confirm that the Meter is
in tracking mode.
2. Move the laser side to side, up and down on the
target area (for example, into the corner of a room).
3. Push
 to stop tracking mode.
The last measured value shows in the summary line.
Note
419D/424D Only: The values for maximum and
minimum distances show in the display. The last
measured value shows in the summary line.
