2.1 Use of the product as directed

The tool is designed for measuring distances, adding and subtracting distances and offers many practical functions such as a timer, area and volume measurement, min/max calculation, setting out, painter’s area measurement, Pythagoras function and data memory. Do not use the tool as a leveling tool. Measurements taken from plastic foam materials such as polystyrene foam, from snow or from highly reflective surfaces (mirrors, glass, etc.) may produce inaccurate results.

The tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used not as directed. Take the influences of the surrounding area into account. Do not use the appliance where there is a risk of fire or explosion. Observe the information printed in the operating instructions concerning operation, care and maintenance. To avoid the risk of injury, use only genuine Hilti accessories and additional equipment. Modification of the tool is not permissible.

NOTE

Observe the permissible operating and storage temperatures.

2.2 Display

The measurements, settings and tool status are shown in the display. When the tool is in measuring mode, the measurements taken are shown at the bottom of the display area (the result line). When using a function, e.g. area measurement, the distances measured are shown in the intermediate result line and the calculated result is shown at the bottom of the display (the result line).

2.3 Display illumination

In low light conditions, the display is illuminated automatically as soon as a button is pressed. The display illumination intensity is reduced to 50% after 10 seconds. If no button is pressed over a period of 20 seconds, the display illumination switches off automatically.

NOTE

Illumination of the display consumes battery power. Shorter battery life is therefore to be expected when this feature is used frequently.

2.4 Basic principle

The distance is measured along a laser beam emitted by the tool to the point at which the beam strikes a reflective surface. The target from which the measurement is taken is clearly identified by the red laser measuring spot. The range of the tool depends on the reflectance and structure of the target surface from which measurements are taken.

2.5 Measuring principle

The tool emits a visible laser beam carrying signal pulses which are reflected by the target. The time between reflected pulses is used as a basis for determining the distance. This measuring principle permits highly accurate and reliable measurement of distances to objects without need for special reflectors.

2.6 Standard measuring display mode

Standard measuring display mode is always activated when the “On/off” or “Measure” button is pressed to switch the tool on.

2.11 PUA 60 laser visibility glasses

The laser visibility glasses have no protective function and thus do not protect the eyes from laser beams. As these glasses limit color vision they must not be worn by persons driving on a public road and must not be used to look directly into the sun. The PUA 60 laser visibility glasses improve laser beam visibility considerably.

2.12 PDA 50 / 51 / 52 target plate

The PDA 50 target plate is made of durable plastic with a special reflective coating. Use of the target plate is recommended at distances greater than 10 m in poor light conditions. The PDA 51 target plate has no reflective coating and its use is recommended in poor light conditions and at short distances. The PDA 52 target plate is equipped with the same reflective coating as the PDA 50 but is considerably larger in size (A4 format, 210 x 297 mm). This makes it much easier to aim the tool at the target plate over long distances.

NOTE

For reliable distance measurements, care should be taken to ensure that the laser beam strikes the target plate at right angles as far as possible. The laser spot on the target plate and the measuring reference point (starting point) may otherwise be in different planes (parallax error).

NOTE

When the target plate is used and very high accuracy is required, 1.2 mm should be added to the measurement obtained.

2.13 PDA 71 measuring extension

The measuring extension is made from aluminium and is equipped with a nonಣconductive plastic grip. The screw on the measuring extension should be screwed into the threaded bush on the rear contact surface of

the PD 42. When the measuring extension is screwed onto the tool, the rear reference is then relocated to the tip of the measuring extension, i.e. the rear reference is extended by 1270 mm (50 inches).

5. Safety rules

In addition to the information relevant to safety given in each of the sections of these operating instructions, the following points must be strictly observed at all times.

5.1 Basic information concerning safety

a) Do not render safety devices ineffective and do

not remove information and warning notices.

b) Keep laser tools out of reach of children. c) Failure to follow the correct procedures when

opening the tool may cause emission of laser radiation in excess of class 2. Have the tool

repaired only at a Hilti service center.

d) Check that the tool functions correctly each time

before use.

e) Operation of the tool in the proximity of pregnant

women is not permissible.

f) Measurements taken from surfaces with low re-

flectivity in highly reflective surroundings may be inaccurate.

g) Measurements taken through panes of glass or

other objects may be inaccurate.

h) Rapid changes in the conditions under which

the measurement is taken, e.g. persons walking through the laser beam, may lead to inaccurate results.

i) Do not point the tool toward the sun or other

ಣ

powerful light sources.

5.2 Proper organization of the workplace

a) Avoid unfavorable body positions when working

on ladders or scaffolding. Make sure you work from a safe stance and stay in balance at all

times.

b) Check the measuring reference setting before

taking the measurement.

c) When the tool is brought into a warm environ-

ment from very cold conditions, or vice allow it to become acclimatized before use.

d) As a precaution, check the previous settings and

adjustments you have made.

e) When setting up the tool with the aid of the

bubble level, view the bubble level at a slight angle.

f) Secure the area in which you are working and

take care to avoid directing the beam towards other persons or towards yourself when setting up the tool.

g) Use the tool only within its specified limits. h) Observe the accident prevention regulations ap-

plicable in your country.

5.3 Electromagnetic compatibility

Although the tool complies with the strict requirements of the applicable directives, Hilti cannot entirely rule out the possibility of the tool being subject to interference caused by powerful electromagnetic radiation, leading to incorrect operation. Check the accuracy of the tool 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.

5.4 General safety rules

a) Check the condition of the tool before use. If the

tool is found to be damaged, have it repaired at a Hilti service center.

versa,

b) The user must check the accuracy of the tool

after it has been dropped or subjected to other mechanical stresses.

c) Although the tool is designed for the tough con-

ditions of jobsite use, as with other measuring instruments it should be treated with care.

d) Although the tool is protected to prevent entry

of dampness, it should be wiped dry each time before being put away in its transport container.

5.5 Electrical

a) Keep the batteries out of reach of children. b) Do not allow the batteries to overheat and do not

expose them to fire. The batteries may explode or release toxic substances.

c) Do not charge the batteries. d) Do not solder the batteries into the tool. e) Do not discharge the batteries by short

ing. This may cause them to overheat and present a risk of personal injury (burns).

f) Do not attempt to open the batteries and do not

subject them to excessive mechanical stress.

5.6 Laser classification

Depending on the version purchased, the tool complies with Laser Class 2 in accordance with IEC825ಣ 1:2003 / EN60825ಣ1:2003 and Class II in accordance with CFR 21 § 1040 (FDA). This tool may be used without need for further protective measures. The eyelid closure reflex protects the eyes when a person looks into the beam unintentionally for a brief moment. This eyelid closure reflex, however, may be negatively affected by medicines, alcohol or drugs. Nevertheless, as with the sun, one should not look directly into sources of bright light. Do not direct the laser beam toward persons.

5.7 Transport

Always remove the batteries before shipping the tool.

DANGER Do not mix old and new batteries. Do not mix batteries of different makes or types.

1. Unscrew the battery compartment cover from the rear of the tool.

2. Remove the batteries from the packaging and insert them in the tool. NOTE Take care to observe correct polarity (see symbols in battery compartment).

3. Check to ensure that the battery compartment cover is closed securely.

6.2 Switching the tool on / off

1. The tool can be switched on by pressing either the “On / off” button or the “Measure” button.

2. When the tool is switched off, press the “On / off” button: The tool switches on. The laser beam is switched off.

3. When the tool is switched on, press the “On / off” button: The tool switches off.

4. Whenthe tool is switched off, press the “Measure” button: The tool and the laser beam switch on.

6.3 First distance measurements

1. Press the “Measure” button once. If switched off, the tool will be switched on and the laser beam activated. If the tool is already switched on, the laser beam will be activated.

2. Aim the tool by positioning the visible laser spot on a white surface at a distance of approx. 3 ಣ 10 m.

3. Press the “Measure” button again. The distance will be displayed in less than a second, e.g. 5.489 m. You have just taken your first measurement with the tool.

6.4 Settings menu

1. With the tool switched off, press the “On / off” button for approx. 2 seconds to enter menu mode.

2. Press the “Plus” button to switch the beep signal on or off.

3. Press the “Minus” button repeatedly to scroll through the choice of units.

4. Press the “On / off” button briefly to close the menu. The tool is switched off and all the settings shown will be saved.

6.5 Measuring references

NOTE

The tool can take measurements from 5 different reference (contact) points. The “Reference” button on the top left on the front of the tool is used to switch between the front and rear references (front or rear edge of the tool). The reference is set automatically to the tip of the spike when the spike is folded out through 180°. When the measuring extension is screwed onto the tool at the rear (at the battery compartment), this is detected automatically by the tool and indicated by the long extension symbol in the

display. The PDA 71 measuring extension can also be fitted to the underside of the tool, but is not detected automatically when in this position.

1. Press the “Measure” button to switch the laser beam on and then aim the tool at the target.

2. Pressthe “Measure” button or the side “Measure” button and aim the tool at the target until the laser spot disappears from the optical sight. The distance is shown in the display.

6.7 Measuring distances

NOTE

When the spike is folded back in, the measuring reference is always reset to the rear edge of the tool irrespective of how far the spike was folded out or to which point on the tool the measuring reference was previously set.

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.

6.7.1 Measuring distances step by step

NOTE

The range meter measures distances in a very short time and simultaneously shows various information in the display.

Switch the tool on by pressing the “On / off” button.

PDA 71 measuring extension screwed on at the rear

6.6 Optical sight 3

NOTE

The optical sight is useful when measuring distances greater than 10 meters.

The builtಣin optical sight is particularly helpful outdoors and in situations where the laser spot is otherwise difficult to see or no longer visible. With the aid of the optical sight, the tool can be aimed accurately at targets even at great distance. When the tool is switched on, the laser spot can be seen in the optical sight. If the laser spot cannot be seen in the optical sight, either the measurement has been successfully completed or the laser beam has switched itself off after the corresponding time interval. The axis of the optical sight lies parallel to the axis of the laser beam.

----------

Press the “Measure” button once. The laser beam is switched on and is visible in the form of a spot on the target surface. This aiming mode is indicated in the display by a blinking laser symbol.

----------

Aim at the target. Press the “Measure” button once again to measure the distance. The result usually appears in the result line in less than a second and the laser beam then switches off.

5.489

If further measurements are taken, up to three previously determined distances are shown in the intermediate result lines, i.e. a total of the last four measured distances are shown.

5.489

12.349

The tool can, of course, be switched on again at any time by pressing the “Measure” button. Pressing the Cಣbutton clears all currently displayed values.

6.7.2 Measuring modes

Distances can be measured using two different measuring modes, i.e. single distance measuring or continuous measuring. Continuous measuring mode is used for setting out given distances or lengths and can also be used where distance measurement is otherwise difficult, e.g. at corners, edges or in niches, etc.

6.7.2.1 Single distance measuring (“Measure” button)

1. Switch the laser beam on by pressing the “Measure” button.

2. Press the “Measure” button again. The measured distance will be shown in the result line at the bottom of the display in less than a second.

6.7.2.2 Single distance measuring (“On /off” button)

1. Switch the laser beam on by pressing the “On / off” button.

2. Press the “Measure” button to switch the laser beam on and then aim the tool at the target.

3. Press the “Measure” button again. The measured distance will be shown in the result line at the bottom of the display in less than a second.

6.7.2.3 Continuous measuring (tracking)

NOTE

Continuous measuring is possible in all situations where individual distances can be measured. This applies also to functions, such as areas.

24.634

27.317

1. Press the “Measure” button for about 2 seconds to activate the continuous measuring mode. NOTE When doing so, it doesn’t matter whether the tool or the laser beam is switched on or off. The tool will always switch to continuous measuring mode. During continuous measuring, distances are up-

dated in the result line at the rate of approx. 6 ಣ 10 measurements every second. The measuring rate depends on reflectivity of the target surface. If the beep signal is active, continuous measuring is indicated by a beep signal approx. 2 ಣ 3 times per second.

2. Measuring is stopped by pressing the “Measure” button once again. The last valid measurement is then shown in the result line in the display.

6.7.3 Measuring from corners 45

The spike is used when measuring diagonally across rooms or from inaccessible corners.

1. Fold out the spike through 180°. The measuring reference is then set automatically to the end of the spike. The range meter takes the extended reference point into account and corrects the measured distances accordingly.

2. Position the range meter with the spike at the desired starting point for the measurement and aim toward the target.

3. Press the “Measure” button. The measured distance is shown in the display.

6.7.4 Measuring with the aid of target

objects 67

When taking measurements to outside corners (e.g. on outside walls of buildings, perimeter fences, etc.), boards, bricks or other suitable objects can be held against the corner and used as the target. Use of the PDA 50, PDA 51 or PDA 52 target plate is recommended for long distances and in unfavorable light conditions, e.g. in strong sunlight.

6.7.5 Measuring in bright conditions

We recommend use of the PDA 50, PDA 51 or PDA 52 target plate for long distances and in very bright light conditions.

6.7.6 Taking measurements to rough surfaces 8

When measuring to rough surfaces, e.g. rough plaster etc., an average distance value is measured with the

center of the laser spot weighted higher than the edges of the laser spot.

6.7.7 Taking measurements to curved or inclined surfaces

If the laser beam strikes the target surface at a very narrow angle, the light reflected may be inadequate. Conversely, too much light may be reflected toward the tool in situations where the laser beam strikes the target perpendicularly. We recommend use of the PDA 50, PDA 51 or PDA 52 target plate in both of these situations.

6.7.8 Taking measurements to wet or shiny surfaces

As long as the range meter can be aimed directly at the surface, the distance to the target will be reliably measured. With highly reflective surfaces, a reduction in range must be expected and the distance to the actual point of reflection may be measured.

6.7.9 Taking measurements to transparent surfaces

It is generally possible to measure distances to transparent or semiಣtransparent materials, e.g. liquids, polystyrene foam, etc. Light penetrates these materials, however, and measuring errors may therefore occur. Measuring errors may also occur when measurements are taken through glass or if objects are present within the line of the laser beam.

6.7.10 Measuring range

6.7.10.1 Increased range

The range of the tool is generally increased when measurements are taken in the dark, at dawn or dusk and when the target and/or the tool is shaded from bright light. Use of the PDA 50, PDA 51 or PDA 52 target plate also increases the range of the tool.

6.7.10.2 Reduced measuring range

Measuring range may be reduced in bright conditions, e.g. in bright sunlight or when working under very powerful floodlights. The range of the tool may be reduced when measurements are taken through glass or when objects lie within the path of the laser beam. The range of the tool may be reduced when measurements are taken to mat green, blue or black surfaces or to wet or shiny surfaces.

7. Operation

NOTE

The direct control buttons are used for adding and subtracting distances. All other functions are activated by pressing the FNCಣbutton.

7.1 Distance measurements

NOTE

With all functions of the tool, each step in the operation is always indicated in the display.

NOTE

Continuous measuring mode can be used with all functions in which individual distance measurement is possible.

NOTE

If measuring errors occur during continuous measuring, and continuous measuring mode is canceled by pressing the “Measure” button again, the last valid measurement will be displayed.

7.2 Adding distances

1. Press the “Measure” button (the laser beam will switch on).

2. Aim the range meter at the target.

3. Press the “Measure” button. The first distance will be measured and displayed (the laser then switches off).

4. Press the “Plus” button. The first distance is then displayed in the middle result line and a plus sign appears in the lower (intermediate) result line (the laser beam switches on).

5. Aim the range meter at the target.

6. Press the “Measure” button. The second distance is then measured and displayed in the lower (intermediate) result line. The result of the addition is shown in the result line. The current total of the distances is always shown in the result line. The procedure can be repeated until all distances have been added.

7. To terminate the addition of distances, simply measure a distance without first pressing the “Plus” button. All previous measuring and calculation results are shown in the intermediate results lines.

8. Press the Cಣbutton to clear the display.

7.3 Subtracting distances

12.349

+ 5.489

17.838

Individual distances can be conveniently added. This is useful, for example, for determining the total length of the inner face of door or window openings or for adding several individual distances that form a perimeter.

3.947

- 3.322

0.625

Individual distances can be conveniently subtracted from each other, e.g. in order to determine the distance between the underside of a pipe and the ceiling.

This can be done by subtracting the distance between the floor and the underside of the pipe from the distance between the floor and the ceiling. If the pipe diameter is subtracted, the result is the distance between the top of the pipe and the ceiling.

1. Press the “Measure” button (the laser beam switches on).

2. Aim the range meter at the target.

3. Press the “Measure” button. The first distance will be measured and displayed (the laser then switches off).

4. Press the “Minus” button. The first distance is then displayed in the middle result line and a minus sign appears in the lower (intermediate) result line (the laser beam switches on).

5. Aim the range meter at the target.

6. Press the “Measure” button. The second distance is then measured and displayed in the lower (intermediate) result line. The result of the subtraction is shown in the result line. The current difference in distance is always shown in the result line. The procedure can be repeated until all distances have been subtracted.

7. To terminate the subtraction of distances, simply measure a distance without first pressing the “Minus” button. All previous measuring and calculation results are shown in the intermediate results lines.

8. Press the Cಣbutton to clear the display.

7.4 Timer

12.349

67.784

Each step of the area measurement operation is indicated graphically in the display. For example, to determine the floor area of a room, proceed as follows:

1. Pressthe FNCಣbutton to activate the area function.

NOTE When the area function is activated, the laser beam is already switched on.

2. Aim the range meter at the target.

3. Press the “Measure” button. The width of the room is measured and the value displayed. The graphic display automatically prompts you to measure the length of the room.

4. Aim the tool at the next target to obtain the length of the room.

5. Press the “Measure” button. The second distance is then measured, the area calculated immediately and the result is displayed in the result line. Both distances used for the area calculation are shown in the intermediate result lines and can be noted down conveniently at the end of the operation.

The timer function works like the selfಣtimer on a camera. The “Plus” and “Minus” buttons can be used to adjust the timer interval to one of the three settings: 5, 10 or 20 seconds. To activate the timer, press the “Measure” button. To stop the timer, press the Cಣ

6. The Cಣbutton can be pressed at any time to stop the measuring operation. Each measurement can then be cleared, one after the other, and measuring restarted. NOTE If the Cಣbutton is pressed several times or the FNCಣbutton is pressed, the function will be canceled or, respectively, restarted. NOTE If the second distance is measured using continuous measuring mode (tracking), the result of the area calculation is updated continuously. This allows parts of the area to be included/ excluded. NOTE After calculation of an area, the “Plus” button can be pressed to add another area or, respectively, the “Minus” button used to subtract an area.

7.6 Measuring volumes

4.347

The “Maximum” function is used mainly to determine the length of diagonals, while the “Minimum” function is used to check parallels and set up objects parallel to each other, or to take measurements in situations where access is difficult. The “Maximum” function makes use of continuous measuring mode. The value shown in the display is updated whenever the measured distance increases. The “Minimum” function also makes use of continuous measuring mode. The value shown in the display is updated whenever

the measured distance decreases. By combining the “Maximum” and “Minimum” functions, differences in distance can be determined very quickly, easily and reliably. The distance between a pipe and ceiling, or the distance between two objects even in inaccessible locations, can thus be easily and reliably determined.

1. Press the FNCಣbutton to activate the “Min/max”

function. NOTE When the “Min/max” function is activated, the laser beam is already switched on.

2. Aim the range meter at the target.

3. Press the “Measure” button. Continuous measuring then begins. The values shown in the MIN and MAX display areas are then updated whenever the measured distance increases or decreases.

4. Press the “Measure” button to stop measuring. The maximum distance, minimum distance and the difference between minimum and maximum are then shown in the display.

5. The Cಣbutton can be pressed at any time to stop the last measuring operation, clear the result and restart measuring. NOTE If the Cಣbutton is pressed several times or the FNCಣbutton is pressed, the function will be canceled or, respectively, restarted. NOTE Further “Undo” steps are not possible. If the Cಣbutton is pressed several times or the FNCಣbutton pressed once, the function will be canceled.

4. Press the “Plus” button again to make the tool ready to measure the next length. The total length is then displayed in the top intermediate result line.

5. Measure the third length and, if necessary, any further lengths.

7.10 Indirect measurements

A distance can be measured indirectly by taking several measurements and the result then calculated using the Pythagoras rule. The indirect measurement functions are accessed by pressing the FNCಣbutton. Three functions are available for use: The “Single Pythagoras” function using a triangle with two measured distances. The “Double Pythagoras” function with 2 adjoining triangles. The “Combined Pythagoras” function using 2 part triangles.

NOTE

A reduced level of accuracy, much lower than the level of accuracy of the tool itself, must generally be expected when the indirect measuring method is used. In order to obtain the best results, care must be taken regarding the geometry of the situation (i.e. right angles and triangle relationships). Best results are obtained when the tool is aimed carefully at the corners of the object, when all points are within the

same plane and when the measurements are taken from a location not too far away from the object.

Follow the symbols in the display. The blinking side of the triangle indicates the measurement to be taken. When the 2 required distances have been measured, the result is then calculated and shown in the result line in the lower area of the display.

1. Press the FNCಣbutton to activate the “Single Pythagoras” function. NOTE When the “Single Pythagoras” function is activated, the laser beam is already switched on.

2. Aim the tool at the target as indicated by the symbol in the display. Press the “Measure” button.

3. The graphic display automatically prompts you to measure the shorter distance.

4. Aim the laser spot at the target and press the “Measure” button. NOTE Please note that this distance is measured in continuous measuring mode in order to ensure that the shortest distance to the target (at right angles) is measured reliably. When the second measurement has been taken, the tool then immediately calculates the opposite “indirect distance”. The system checks whether the geometric relationship allows a result to be calculated. An invalid result, due to inappropriate geometry, is indicated by the result line blinking (broken line). In this case, one or both of the distances must be remeasured.
