Introduction
The Fluke 414D, 419D, 424D Laser Distance Meters
(Meter or Product) are professional-grade laser distance
meters. Use these Meters to quickly and accurately get
the distance to a target, the area, and the volume
measurements.
This Meter is better than an ultrasonic device because it
uses laser light waves and measures their reflection. The
Meter includes:
•Most advanced technology for distance
measurements
•More accurate measurement
•Longer measurement distance – model dependent
This manual identifies when a feature is
model-dependent. If not identified, all models include the
feature.

Safety Information
A Warning identifies hazardous conditions and
procedures that are dangerous to the user.
W* Warning
To prevent eye damage and personal injury:
•Read all safety information before you use the
Product.
•Carefully read all instructions.
•Use the Product only as specified, or the
protection supplied by the Product can be
compromised.
•Do not use the Product around explosive gas,
vapor, or in damp or wet environments.
•Do not use the Product if it operates incorrectly.

Multifunctional Endpiece
The 419D and 424D Meters adapt to multiple
measurement situations with the multifunctional endpiece.
See Figure 2:
•For measurements from an edge, fold out the
endpiece (90 °) until it locks into place. See Figure 3.
•For measurements from a corner, fold out the
endpiece (90 °) until it locks into place. Push the
endpiece lightly to the right side to fold it out fully. See
Figures 2 and 4.
•A built-in sensor automatically senses the orientation
of the endpiece and adjusts the zero point.

Timer (419D/424D)
Fluke recommends that you use a time-delay for the most
accurate measurements at long distances. This prevents
Meter movement when you push .
To turn on the timer:
1. Push
1x to turn on the 5-second timer. This is the
default time interval to release the laser for a
measurement.
2. Push
to increase up to 60 seconds.
3. Push
to decrease the seconds.
4. Push to begin the timer.
The seconds until measurement (for example, 59,
58, 57...) show as a countdown. The last 5 seconds
count down with a beep. After the last beep, the
Meter makes the measurement and the value shows
on the display.
Note
The timer is useful for all measurements.
Beeper (419D/424D)
Push at the same time for 2 seconds to turn on
and turn off the beeper. The display shows the status as
  or  .
Backlight (419D/424D)
Push at the same time for 2 seconds to turn on
and turn off the backlight. The display shows the status

Compass (424D)
The compass feature lets you know the view or direction
as you make measurements. This is useful indoors to set
the building plans in the correct direction. It is also useful
to know the correct direction when you calculate the
efficiency for a solar panel.
Tips:
•Make sure that the endpiece is folded in.
•When you use the compass feature, the Meter shows
the calibration message. See Compass Calibration for
more information.
•Compass arrows blink on the display if the Meter is
tilted >20 °end to end or >10 °side to side.
•When you turn on the compass, the Meter shows the
calibration message. See Manual Calibration for more
information.
Push :
•1x = Arrow points in north direction
•2 seconds = Arrow points in direction of Laser beam
and display shows the direction in degrees and an
alpha symbol.
WCaution
To prevent incorrect direction readouts, do not use
near magnets and magnetic devices.
Compass Calibration
Automatic Calibration
The compass sensor continuously collects and saves
new calibration values in 60-second intervals.
Manual Calibration
When you turn on the compass, the Meter shows the
calibration message:
1. For no, push . The compass uses old data that can
be inaccurate.
2. For yes, push .

To continue with the calibration:
3. Rotate the Meter 180 °around the Z-axis. See
Figure 7.
4. Rotate the Meter 180 °around the X-axis.
5. Rotate the Meter 180 °around the Y-axis.
The Meter counts from 1 to 12 during calibration.

Magnetic Declination
The difference between the north geographic pole and
the north magnetic pole is known as magnetic declination,
or more plainly, declination. The angle of declination is
different at different locations on the earth. The
geographic and magnetic poles are aligned so declination
is minimal. From some locations, the angle between the
two poles can be fairly large.
Table 4 is a list of the current angles of declination by
location. For other declination values, contact your local
Geomagnetic Institute.
To set the Meter with the correct compensation for your
location:
1. Push at the same time.
The display shows  and the current setting.
The default value is 0 °.
2. Push and to change the value.
3. Push to accept the new value.

Measurements with a Tripod
Measurements with the 419D and 424D that use a tripod
must have the tripod reference set. When set, shows on
the display.
Reference Point
The display shows the reference point for a
measurement. The default reference point is from the end
of the Meter. If the beeper is on, the Meter beeps as you
change the reference point. See Figure 8 for more
information.

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 9.
