Introduction

The Fluke 417D and 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:

Measurements with a Tripod

Measurements with the 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 4 for more information.

The Meter automatically adjusts the reference point when you use the endpiece and ▲ shows on the display.

The tripod mode overrides other reference points. The Meter stays in the tripod mode until you change to a different reference point.

Figure 4. Change Reference Point

[Description of Figure 4: Illustrates the different reference point options for measurements, including Default, Measure from front, Measure from tripod screw, Measure from end, and Auto-detect.]

The Meter adds and subtracts a value to a single distance, area, and volume measurements.

To add or subtract:

  1. Push [Plus button] to add the next measurement to the previous measurement, or push [Minus button] to subtract the next measurement from the previous measurement.
  2. Do these steps again for each measurement.

The total measurement result is always shown in the summary line with the value before in the second line.

  1. Push [Clear/Off button] to cancel the last step.

Compass

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. See Table 7.

Tips:

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 [Minus button]. The compass uses old data that can be inaccurate.
  2. For yes, push [Timer button].

To continue with the calibration:

  1. Rotate the Meter 180° around the Z-axis. See Figure 5.
  2. Rotate the Meter 180° around the X-axis.
  3. Rotate the Meter 180° around the Y-axis.

The Meter counts from 1 to 12 during calibration. ▲ OK CAL shows on the display when the calibration is complete.

Figure 5. Manual Calibration

[Description of Figure 5: Shows the sequence of rotations (Z, X, Y axes) required for manual compass 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 9 is a list of the current angles of declination by location.

Timer

Fluke recommends that you use a time-delay for the most accurate measurements at long distances. This prevents Meter movement when you push [Measure button].

To turn on the timer:

  1. Push [Timer button] 1x to turn on the 5-second timer. This is the default time interval to release the laser for a measurement.
  2. Push [Plus button] or [Minus button] to adjust the timer up to 60 seconds.
  3. Push [Measure button] 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.

The timer is useful for all measurements.

Beeper

Push [Beeper symbol] at the same time for 2 seconds to turn on and turn off the beeper. The display shows the status as BEEP On or BEEP OFF.

Stake Out Measurement

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 10 for more information.

For best results, use the end reference point for a stake out measurement. See Reference Point.

Figure 10. Stake Out Measurement

[Description of Figure 10: Shows how to use the stake out function to mark off defined lengths, illustrating cases where a=b and a≠b.]

You can enter two different distances (a and b) into the Meter and use them to mark off measured lengths, for example, in the construction of wooden frames.

To find stake out distances with 2 values:

  1. Push [Stake Out button] 4x. ▲ shows in the display.
  2. Push [Plus button] and [Minus button] to increase or decrease the values that show on the display. The value (a), and the intermediate line that corresponds, blink on the display.
  3. Push [Plus button] and [Minus button] to adjust the (a) value.

Hold the buttons down to increase the rate of change for the values.

  1. Push [Measure button] to accept the (a) value.
  2. Push [Plus button] and [Minus button] to adjust the (b) value.
  3. Push [Measure button] to accept the (b) value.

The display shows the stake out distance in the summary line between the stake out point (a and then b) and the Meter (rear reference).

7. Move the Meter slowly along the stake out line the displayed distance decreases. ► The arrows in the display indicate in which direction the Meter needs to be moved in order to achieve the defined distance (either a or b).

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.

  1. Push [Clear/Off button] to stop the stake out function.

Corner Angle Measurement

The Meter calculates the angles in a triangle with measurements from the three sides. As an example, use this function with a right-angle room corner. See Figure 11 for more information.

To make corner angle measurements:

  1. Push [Corner Angle button] 1x. ▲ (room corner) shows in the display.
Figure 11. Corner Angle Measurement

[Description of Figure 11: Illustrates measuring the angles in a triangle using three side measurements, applicable to room corners.]

  1. Put marks for the reference points to the right and left (d1/d2) of the angle for measurement.
  2. Push [Measure button] to make a measurement of the first side of the triangle (d1 or d2).
  3. Push [Measure button] to make a measurement of the second side of the triangle (d1 or d2).
  4. Push [Measure button] to make a measurement of the third side of the triangle (d3).

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.

Make sure that you use the correct sequence of measurement:
