Fluke 414D, 419D, 424D - Laser Distance Meter Manual

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

identifies hazardous conditions and procedures that are dangerous to the user.

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.

Before You Start

This section has basic information about the batteries and measurement reference point. It also describes the Meter keypad and display.

Batteries

Replace the batteries when blinks in the display.

To install or replace the batteries:

1. Remove battery compartment lid. See Figure 1.
   
   
2. Attach the handstrap.
3. Install two AAA (LR03) batteries with the correct polarity.
   Note
   Do not use zinc-carbon batteries.
4. Close the battery compartment.

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.

To unlock:

2. Push .
3. Push within 2 seconds to unlock the keypad.

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.

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. shows on the display when the calibration is complete.

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.

414D

   Note
   If the beeper feature is on, the Meter starts to beep at a distance of 0.1 m (4 in) from the next stake out point. As the Meter moves near to the stake out point, the beep changes and the arrows do not show on the display.
8. Push to stop the stake out function.

Corner Angle Measurement (424D only)

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.

EMC International	IEC 61326-1: Industrial Electromagnetic Environment CISPR 11: Group 1, Class A
Group 1: Equipment has intentionally generated and/or uses conductively-coupled radio frequency energy that is necessary for the internal function of the equipment itself. Class A: Equipment is suitable for use in all establishments other than domestic and those directly connected to a low-voltage power supply network that supplies buildings used for domestic purposes. There may be potential difficulties in ensuring electromagnetic compatibility in other environments due to conducted and radiated disturbances.. KCC: Class A Equipment (Industrial Broadcasting & Communication Equipment) Class A: Equipment meets requirements for industrial electromagnetic wave equipment and the seller or user should take notice of it. This equipment is intended for use in business environments and not to be used in homes. USA (FCC): 47 CFR 15 subpart B. This product is considered an exempt device per clause 15.103.
Applies for 100% target reflectivity (white painted wall), low background illumination, 25°C. Applies for 10% to 500% target reflectivity, high background illumination, −10°C to +50°C. Tolerances apply from 0.05 m to 10 m with a confidence level of 95%. The maximum tolerance may deteriorate to 0.15 mm/m between 10 m to 30 m and to 0.2 mm/m for distances above 30 m. Applies for 100% target reflectivity, background illumination ~30,000 lux. After user calibration. Additional angle related deviation of ±0.01 ° per degree up to ±45 ° in each quadrant. Applies at room temperature. For the whole operating temperature range the maximum deviation increases by ±0.1 °. After calibration. Do not use the compass for navigation.
