LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service. The warranty period is
two years and begins on the date of shipment. Parts, product repairs, and services are warranted for 90 days. This warranty extends only to
the original buyer or end-user customer of a Fluke authorized reseller, and does not apply to fuses, disposable batteries, or to any product
which, in Fluke's opinion, has been misused, altered, neglected, contaminated, or damaged by accident or abnormal conditions of operation
or handling. Fluke warrants that software will operate substantially in accordance with its functional specifications for 90 days and that it has
been properly recorded on non-defective media. Fluke does not warrant that software will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to
extend a greater or different warranty on behalf of Fluke. Warranty support is available only if product is purchased through a Fluke
authorized sales outlet or Buyer has paid the applicable international price. Fluke reserves the right to invoice Buyer for importation costs of
repair/replacement parts when product purchased in one country is submitted for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or replacement of a defective
product which is returned to a Fluke authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center to obtain return authorization information, then send the
product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). Fluke assumes no risk
for damage in transit. Following warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke
determines that failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition of operation or handling,
including overvoltage failures caused by use outside the product’s specified rating, or normal wear and tear of mechanical components,
Fluke will provide an estimate of repair costs and obtain authorization before commencing the work. Following repair, the product will be
returned to the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping
Point).

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.
• Do not use the Product if it is damaged.
• Disable the Product if it is damaged.
• Do not look into the laser. Do not point the laser
directly at persons or animals or indirectly off
reflective surfaces.
• Do not look directly into the laser with optical
tools (for example, binoculars, telescopes,
microscopes). Optical tools can focus the laser
and be dangerous to the eye.
• Do not open the Product. The laser beam is
dangerous to eyes. Have the Product repaired
only through an approved technical site.
• Remove the batteries if the Product is not used
for an extended period of time, or if stored in
temperatures above 50 °C. If the batteries are not
removed, battery leakage can damage the
Product.
• Replace the batteries when the low battery
indicator shows to prevent incorrect
measurements.

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.

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.

W Caution
To prevent incorrect direction readouts, do not use

Automatic Calibration
The compass sensor continuously collects and saves
new calibration values in 60-second intervals.

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 default value is 0 °.
2. Push and to change the value.

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.

Stake Out Measurement (419D/424D)
A specific distance can be set in the Meter and used to
mark off defined measured lengths. An example of this
application is in the construction of wooden frames. See
Figure 13 for more information.
Note
For best results, it is recommended to use the
end reference point for a stake out
measurement. See Reference Point.

Measurements
Indirect Measurement
The Meter can calculate distances with Pythagoras’
theorem. With this function, you can find a distance with
two auxiliary measurements, such as building height or
width measurements. It is helpful to use a tripod for a
height measurement that uses two or three
measurements.
Note
Make sure that you use the correct sequence of
measurement:
• All target points must be in a horizontal or
vertical plane.
• For the best results, turn the Meter about a
set point. An example of this is with the
endpiece fully open and the Meter on a wall.
• Make sure that the first measurement and
the measurement distance are at 90 °
angles.
• The minimum/maximum tracking is very
helpful for 90 ° angle measurements. See
Minimum/Maximum Tracking.
