ft2, ft3or “no unit”.

When the entry made is unrealistic, the PD 25 reacts by causing the display to blink.

Example 1: Measured value [m] + value entered [m], e.g. 1.155 m + 5.2575 m

Example 2:Area [m

] + area entered [m2], e.g. 3.078 2 m2+ 91 m

Example 3: Measured value [in 1/32] x value entered [in 1/32], e.g. (7´ 4” 29/31) x (8” 5/32)

The value entered is set to the unit “m”.

The entries can be made in the same way when the unit is set to ft or in.

The measuring

reference point is

altered automatically .

Check the measu-

ring reference point.

The tool takes the extended measuring reference into account and automatically corrects the distance measured by this value. The measuring procedure is as previously described.

4. Working with the PD 25

Measuring using the self-timer

The use of an extension rod can be of great assistance for measuring with the PD 25 from points where access is difficult or even impossible to reach without some form of aid. One of the two threaded bushings (1/4” tripod thread) on the PD 25 can be used for attaching an extension rod.

When an extension rod is used, the delay between pressing the “measure” button and the moment at which the measurement is taken can be set with the assistance of the self-timer (delay) function.

Set the delay time

The measurement is taken after: 0/2/5/10/20 seconds

Press the arrow button repeatedly until the desired delay has been set.

T aking measurements from various surfaces

Plants and trees

As a rule, it is not possible to take measurements from plants and trees, even over very short distances. Matt green surfaces decrease the range of the PD 25.

Rough surfaces

On rough surfaces, (e.g. rough plaster), the measurement obtained is a weighted average, whereby the centre of the laser beam receives a higher weighting than the surrounding area.

Measuring with the aid of a target object

Aboard, bricks or other suitable objects can be used as the target when taking a measurement from an outside edge (e.g. outside walls of houses, perimeter fences etc).

4. Working with the PD 25

Continuous measurement (tracking)

Switch the tool on.

Press the “measure” button once (long press) (=tracking). The words “LASER TRACKING” appear in the display:

Example 2: Calculating the volume of a room

After calculating the floor area of the room:

Press “x” for multiplication. Measure the height of the room.

Press the “equals” button.

The volume can then be read from the display .

Consecutive calculations can also be made without pressing the “equals” button. e.g. distance x distance x distance = m

(distance x distance) + (distance x distance) = m

The subtraction, square and square root functions can be used in the same way . Manually entered values or values from intermediate memory can also be used for all calculation functions.

When the calculation is unrealistic (e.g. m

x m3) the display begins

to blink.

8. Measuring equipment inspection

Measuring equipment inspection of the PD 25 for users certified according to ISO 900...

Y ou may carry out the measuring equipment inspection required by ISO 900... on the PD 25 linear measuring device yourself (see DIN 18723-6; Procedures for checking the accuracy of geodetic instru-

ments in the field: Part-6, opto-electronic range meters for short distances).

To do this, select a measuring distance which remains constant over a period of time and which is easily accessible. It should have a known length of approx. 1 to 5 m (e.g. a window opening or the width of a room) and 10 measurements should be made.

Determine the deviation of the readings from the nominal measuring distance and calculate the standard deviation on this basis.

Make a note of this value and the date or time for the next inspection.

Repeat these verification measurements at regular intervals as well as before and after important measuring tasks.

Apply a measuring equipment inspection sticker to the PD 25 and document the entire inspection procedure.

Y our PD 25 conforms to the specified accuracy if the standard deviation remains less than or equal to 3mm.

APD 25 which has been tested / inspected over the test distance will operate with the accuracy specified in the operating instructions over the entire specified length and temperature range. Please refer to the technical data contained in the operating instructions and to the explanation of the accuracy values.

Recommendation

Test the tool, or have it tested, once a year. Contact your Hilti representative for further information. The tool can also be tested at one of our repair / service centres where confirmation of inspection can be given and, when necessary , a certificate issued for your documentation.
