Indirect distance measurement is used to measure distances that cannot be measured directly because an obstacle would obstruct the laser beam or no target surface is available as a reflector. This measuring procedure can only be used in a vertical direction. Any deviation in a horizontal direction leads to measuring errors.

Indirect distance measurement is always less accurate than direct distance measurement. For application-related reasons, measuring errors can be greater than with direct distance measurement. To improve measuring accuracy, the use of a tripod (accessory) is recommended.

When using a tripod, observe the set reference level. see Selecting the Reference Level

The laser beam remains switched on between the individual measurements.

For indirect distance measurement, 4 measuring functions are available, with which different sections can be respectively determined:

  • Indirect height measurement
  • Double indirect height measurement
  • Indirect length measurement
  • Trapezoid measurement

Indirect Height Measurement

With indirect height measurement, you can determine distance AB by measuring distance 1. The measuring tool calculates the required height AB from angle  and distance 1.

Correct results are achieved only when the right angle required for the respective measurement is exactly adhered to.

  6. Press the  button to start the measurement.

With indirect length measurement, you can determine distance AB by measuring distance 1. The measuring tool calculates the required length AB from angle  and distance 1.

After the measurement has been completed, the length will be automatically calculated and displayed in the result line (a). The measured values for section 1 and angle  are in the measured value lines (h).

Trapezoid Measurement

With trapezoid measurement, the length of a sloping roof can, for instance, be determined. You can determine section AB by measuring sections 1, 2 and 3 in this order. The measuring tool calculates the required section AB from sections 1, 2 and 3.

Ensure that the measurement of distance 3 begins exactly at the point where distance 1 ends that there is a right angle between both distances 1 and 2 and distances 1 and 3.
  1. Press the  button to open the Functions menu.
  2. Select indirect distance measurement  and confirm the selection with the  button.
  3. Select trapezoid measurement and confirm the selection with the  button.
  4. Briefly press the  button to switch on the laser.
  5. Measure section 1 with the  button.
  6. Measure section 2 with the  button.
  7. Measure section 3 with the  button.

After the measurement has been completed, section AB will be automatically calculated and displayed in the result line (a). The measured values for sections 1, 2 and 3 are in the measured value lines (h).

The wall area measurement is used to determine the sum of multiple individual areas with a common height. The requirement for a correct area calculation is that the first measured length (for example the ceiling height H) is identical for all sub-areas. In the illustrated example, the total area of several walls that have the same ceiling height H but different lengths L is to be determined.

  1. Press the  button to open the Functions menu.
  2. Select wall area measurement  and confirm the selection with the  button.
  3. Measure the ceiling height H as for a length measurement.
  4. The measured value is displayed in the top measured value line. The laser remains switched on.
  5. Afterwards measure the length L1 of the first wall.
  6. The area is automatically calculated and displayed in the result line. The last measured value for length can be found in the bottom measured value line. The laser remains switched on.
  7. Now measure the length L2 of the second wall.

You can measure any number of lengths LX, which will be automatically added and multiplied by the height H.

The individual measured value displayed in the measured value line (h) is added to the length L1. The sum of the two lengths (displayed in the middle measured value line (h)) is multiplied by the saved height H. The total area value is shown in the result line (a) at the bottom of the display.

In the stake-out function, the reference level is the marking shown in the display. The reference level is not the edge of the measuring tool.

The stake-out function repeatedly measures a defined length (distance). These lengths can be transferred to a surface, for example to enable material to be cut into pieces of equal length or to install stud walls in a drywall construction. The minimum adjustable length is 0.1 m and the maximum length is 50 m.

  1. Press the  button to open the Functions menu.
  2. Select stake-out function  and confirm the selection with the  button.
  3. Press the  button to set the required length.
  4. Use the  button or the  button to set the required length.
  5. Press and hold the  button or the  button to change the length by larger increments.
  6. Press the  button to start the stake-out function and distance yourself slowly from the starting point.
  7. The measuring tool continuously measures the distance to the starting point. The defined length and the current measured value are thereby displayed. The lower or upper arrow displays the shortest distance to the next or previous marking.
  8. With continuous measurement, you can also establish a measured value as a defined length by pressing and holding the  button.

The left factor specifies how many times the defined length has already been reached. The green arrows on either side of the display indicate the reaching of a length for marking purposes.

Red arrows and red text indicate the actual value when the reference is outside the display.

The digital spirit level is used to check the horizontal or vertical alignment of an object (e.g. washing machine, refrigerator, etc.). Grade measurement is used to measure a slope or incline (e.g. of stairs, railings, when fitting furniture, laying pipes, etc.). The measuring tool automatically switches between the two functions when you change the position of the measuring tool.

  1. Press the  button to open the Functions menu.
  2. Select grade measurement/digital spirit level  and confirm the selection with the  button.

The bottom of the measuring tool is used as the reference level for the digital spirit level.

  1. To use the digital spirit level, place the measuring tool with the rear side on the surface to be measured.
  2. You can freeze the measured value by pressing the  button.
  3. When the inclination exceeds 3°, the ball in the display lights up red.

The left-hand side of the measuring tool serves as the reference level for grade measurement. If the display flashes during measurement, the measuring tool has been tipped too heavily to the side.

  1. To use the grade measurement, place the measuring tool with one side on the object to be measured.
  2. You can freeze the measured value by pressing the  button.

During continuous measurement, the measured value is continually updated. You can, for example, move a required distance away from a wall while reading off the current distance at all times.

  1. Press the  button to open the Functions menu.
  2. Select continuous measurement  and confirm the selection with the  button.
  3. Briefly press the  button to switch on the laser.
  4. Move the measuring tool until the required distance is displayed in the result line.
  5. You can interrupt the continuous measurement by briefly pressing the  button.
  6. Press the  button again to continue the continuous measurement.

The current measured value is displayed in the result line (a), and the maximum and the minimum measured value in the measured value lines (h).

Continuous measurement switches off automatically after 5 min.
