Electromagnetic compatibility

Although the device complies with the strict requirements of the applicable directives, Hilti cannot entirely rule out the possibility of interference to the device caused by powerful electromagnetic radiation, possibly leading to incorrect operation. Check the accuracy of the device by taking measurements by other means when working under such conditions or if you are unsure. Likewise, Hilti cannot rule out the possibility of interference with other devices (e.g. aircraft navigation equipment). The tool complies with the requirements of class A; The possibility of interference occurring in a domestic environment cannot be excluded.
Only for Korea: This laser range meter is suitable for commercial and industrial use and for the electromagnetic radiation encountered in this field (Class A). Users must pay attention to this point and make sure that this laser range meter is not used in occupied living areas.

Intended use

The product described is a laser range meter. It is designed for taking individual measurements as well as the continuous measurement of distances.

Distances can be measured from all stationary targets without a highly reflective surface, i.e. concrete, stone, wood, plastic, paper, etc. The use of prisms or other highly reflective targets is not permissible and, if attempted, may falsify the results.
The product is approved for use with batteries of the type AAA.

Basic functions

Navigate to the desired function with the aid of the left or right arrow buttons.

• Always press the “Measure” button to select a function.
  

Inserting the batteries

• Open the battery compartment and insert the batteries.
  

Switching the laser range meter on and off

1. If the tool is switched off, press the on/off button or the “Measure” button to switch it on.
   
2. If the tool is switched on, press the on/off button to switch it off.
   

Measuring using the spike

1. Fold out the spike through 90°. The spike can then be used as the contact point.
   
   Here, the spike helps to align the device while a stable position is established. This is the case primarily for indirect, trapezoid and Pythagoras measurements since these results are based on estimated values.
   Use the measuring extension PDA 72 for inaccessible places. The device automatically detects the measuring extension. A confirmation window may appear in the display.
   

2. Fold out the spike through 180°. The measuring reference point is then set automatically.
   

Measuring using a target plate

1. Use the target plate to measure distance under the following unfavorable conditions:
   
   • The wall is not sufficiently reflective due to the type of surface.
     
   • The target point is not on a surface.
     
   • The distance to be measured is very long.
     
   • The light conditions are unfavorable (bright sunshine).
     
2. A distance of 1.2 mm should be added to the measured distance when using a target plate.
   

Single measurements

1. Press the “Measure” button briefly to activate the laser beam.
   
2. Keep the laser beam on the target point.
   
3. Press the “Measure” button briefly to take the measurement.
   
   • The measured distance is shown in the lower line of the display.
     
   • The distance measured in the previous measurement is shown in the upper line of the display.
     
4. To take another measurement, keep the laser beam on the target point and press the “Measure” button again.
   

Continuous measurement

1. Press the “Measure” button for 2 seconds.
   
   • If the signal tone is active, a signal tone will be emitted.
     
2. Move the laser range meter toward or away from the target until the desired distance is reached.
   
3. Press the “Measure” button briefly.
   
   • The measured distance is shown in the lower line of the display.

4. Select the flag symbol.
   
   • The distance you have entered will then be shown between the two flags.
     
5. Press the “Measure” button to begin measuring.
   
   • The arrows on the screen indicate in which direction you must move the tool. When the target distance is reached, black arrows appear above and below the distance shown in the display.
     
6. To repeat this distance measurement several times, move the tool further. The number of times you have measured out this distance is shown on the right of the screen.
   
7. Press the “Measure” button to stop measuring.
   
   When the distance to be set out is reached, the currently used measuring reference is shown in the display.
   
   As an alternative to entering the distance manually, the distance to be set out may also be measured with the tool. To do this, select the symbol for single measurement and confirm your choice by pressing the “Measure” button.
