Direct Measurements Using The 'Direct' Function; Determining And Documenting Distances In Pictures Using The 'Picture' Function - Hilti PD-C Manual De Instrucciones Original

6 Working with the measuring application

6.1 Direct measurements using the 'Direct' function

6.1.1 Taking single, direct distance measurements
1. Select the project for which you wish to take the measurement.
2. Select the 'Direct' option from the 'Functions' menu.
◁ The laser is switched on and a measure button icon appears on the display.
3. Position the base of the tool on the starting point of the measurement. When doing so, ensure that the
tool is in a stable position.
4. Maintaining the stable position of the tool, aim the laser spot at the end point of the measurement.
5. Tap on the measure button icon or press a measure button.
◁ The measurement ends and the result is displayed.
◁ You can access additional information about the result by tapping on the information icon.
Note
You can add a picture for annotation purposes by tapping on the camera icon, or you can swipe
the results list to the left to inspect the target picture for the measurement.
6.1.2 Continuous measuring (tracking) mode
This mode is activated by holding down the measure button for a longer time, and is particularly useful when
using the 'Horizontal', 'Vertical', 'Maximal' or 'Minimal' triggers.
6.1.3 Activating continuous measuring (tracking) mode
1. To activate the continuous measuring (tracking) mode, hold down one of the measure buttons for roughly
two seconds.
◁ Once continuous measuring (tracking) is activated, the audible signal will sound 2–3 times per second
and the distance will be shown in the middle of the display on a continuous basis.
2. To deactivate continuous measuring (tracking), tap the distance shown in the middle of the display or
press one of the measure buttons.
◁ The audible signal stops and the last valid measurement is displayed.
Note
You can switch off the audible signal in the settings for the measuring application.

6.2 Determining and documenting distances in pictures using the 'Picture' function

There are two functions that allow distances to be determined and documented directly in a picture taken
using the integrated camera.
• Determine distances in pictures ('Measure from picture')
Draw in pictures ('Draw in picture')
•
The integrated front camera is optimized to detect the laser spot at greater ranges and is therefore equipped
with a narrow field of vision. To obtain pictures of wider areas, the distance from the object to be surveyed
must be increased accordingly.
6.2.1 'Measure from picture'
This function provides approximate values for distances you plot with lines along certain elements in the
picture. These lines must be drawn on a level surface (2D), such as on a wall, façade or ceiling.
Examples of applications for the 'Measure from picture' function:
• Estimation of an approximate distance, e.g. the minimum height of a ladder in relation to the height of a
wall so that the top of the wall will remain within reach
• Estimation of the room available for the installation of a fascia on a façade
If the laser beam is aligned at right angles (90°) to the level surface, the estimation is accurate to ±1‒2%.
The limitation of this function compared to the next function, 'Draw in picture', is that when taking
measurements and surveying, the right angle has to be maintained exactly. The tool is unable to ascertain
whether the camera angle is correct or whether the surface in the picture is level. In this case, the deviation
between the estimation and the actual measurement would be significant.
