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.

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.

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.

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:

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.

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.
W Caution
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. 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.

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.

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

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.
