8. Measuring equipment inspection
Measuring equipment inspection of the PD 25 for users certified according to ISO 900. You 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 instruments 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. Your PD 25 conforms to the specified accuracy if the standard deviation remains less than or equal to 3mm. A PD 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.

5. Safety information

5.1 Basic safety information In addition to the safety precautions listed in the individual sections of these operating instructions, the following points must be strictly observed at all times.

5.2 Misuse

The range meter and its accessories can be a source of hazard if they are not used properly or not used for the intended purpose by untrained people. Do not use the range meter without suitable prior instruction. Do not render any safety devices ineffective and do not remove information and warning notices. Have the range meter repaired only at a Hilti service center. Unauthorized opening of the range meter may cause the emission of laser radiation in excess of class 2. No changes or manipulations to the range meter are allowed. Use only original Hilti accessories and auxiliary tools in order to avoid the risk of injury. Do not use the range meter in atmospheres where there is a risk of explosion. Use only a clean, soft cloth for cleaning. If necessary, moisten the cloth slightly with pure alcohol. Keep the range meter out of the reach of children. Measurements taken to plastic foam materials, such as polystyrene foam, or to snow or other strongly reflecting surfaces, may be inaccurate.
Taking measurements to surfaces with low reflectivity surrounded by areas with high reflectivity may lead to measurement errors. Measurements taken through panes of glass or other objects may be inaccurate. Rapid changes of the measuring conditions, e.g. persons walking through the laser beam, may lead to measurement errors. Do not direct the range meter towards the sun or other sources of bright light. Do not use the range meter as a levelling tool. If you do not check the range meter before taking important measurements and after it has been dropped or subjected to other mechanical stressing. Check the setting of the measuring reference before measuring. 5.3 General safety precautions Check the range meter for possible damage before use. If the range meter is found to be damaged, have it repaired at a Hilti service centre. The accuracy of the range meter must be checked after it has been dropped or subjected to other mechanical stressing. When the range meter is brought into a warm environment from very cold conditions, or vice versa, allow it to become acclimatised before use. Although the range meter is designed for the tough conditions of jobsite use, it should be treated with care, as other optical instruments (binoculars, spectacles, cameras, etc.) Although the range meter is protected to prevent entry of dampness, it should be wiped dry each time before being put away in its transport container. As a precaution, check the settings you have made before using the range meter.

5. Safety information When using the circular bubble level (bull's eye) for alignment, only look at the range meter from the side. 5.4.2 Laser classification The range meter conforms to laser class 2 based on the IEC825-1 / EN60825-01 standard and class II based on CFR (FDA). These range meters may be used without need for further protective measures. The eyelid closure reflex protects the eyes if a person looks into the beam unintentionally for a brief moment. The eyelid closure reflex can, however, be negatively influenced by medication, alcohol or drugs. Nevertheless, as with the sun, a person should not look directly into sources of bright light. The laser beam should not be directed towards persons.
5.4 Proper organization of workplace
Secure the area in which you are measuring. When setting up the range meter, take care to avoid directing the beam towards yourself or other people. Avoid unfavourable body position when working on ladders or scaffolding. Make sure you have a stable stance and avoid danger of overbalancing at all times. Measurements taken through panes of glass or other objects may be inaccurate. Use the range meter only while observing the specified operating conditions, i.e. not directed towards a mirror, bright chromium steel, polished stone, etc. Observe the accident prevention regulations in force in the country you are working. 5.4.1 Electromagnetic compatibility Although the range meter complies with the strict requirements of the relevant guidelines, Hilti cannot entirely rule out the following possibilities: The range meter might cause interference to other equipment, e.g. aircraft navigational equipment. The range meter might be subject to interference caused by powerful radiation, which can then lead to incorrect operation. Check the readings for plausibility when measuring in these conditions or if you are unsure of the results.

Laser information plates for the US based on CFR (FDA) This laser product complies with 21 CFR 1040, as applicable. 5.4.3. Transport Remove the alkaline or rechargeable batteries whenever transporting the range meter.

6. Getting started

6.1 Inserting alkaline / rechargeable batteries - CAUTION Observe the polarity of the batteries. (refer to signs inside the battery compartment.) Make sure the battery compartment is properly locked. 1. Lightly press the lid of the battery compartment. 2. Slide the lid out and off. 3. Replace the batteries.

same age and charged to the same level. New rechargeable batteries are mostly empty and have to be charged prior to first use. Use only NiMH batteries with 1.2 V and mAh capacity. 6.2 Battery charging 6.2.1 Standard charging of batteries The charging process ensures that the there will be no "memory effect". In view of this, charging can begin at any time regardless of the level to which the battery is already charged. Attach the PDAW 80/81-1 charging adaptor into the range meter. For charging either connect the mains adapter or the car battery plug to the charging adaptor.
- NOTE For alkaline batteries Always replace a complete set of batteries. Do not mix used and new batteries. Do not mix batteries of different makes or types. Use only undamaged batteries of an approved type. For rechargeable batteries Always use rechargeable batteries of the same make and same type. Always use rechargeable batteries of the
The maximum. charging time is 12 hours. As with many mobile phones, the level of charging is shown by movement of battery display segments.
6. Getting started 6.2.1.1 Battery charging level display The level of charging is indicated by moving battery status segments at the top on the right of the display. When a battery is fully charged, Accu Full (battery full) will be displayed. 6.2.1.2 Charging display for unintentionally inserted alkaline batteries If alkaline batteries are identified, all battery status segments flash continually to indicate missing rechargeable batteries. Additionally, they sign no Accu shows in the display. The range meter cannot be switched on. If defective or non re-chargeable alkaline batteries are inserted, the battery display will flash and, at the same time, Accu dEF (defective battery) will appear in the display. - NOTE At any time while the batteries are being charged, the range meter can be switched on and used. The battery charging process stops when the range meter is switched on and the laser activated. Rechargeable batteries discharge if they are stored for a long time. The battery charging process terminates after 1 minute when charging very empty rechargeable batteries and the display switches off in this case, the charging process can be re-started only by disconnecting the range meter from the mains adaptor or by removing / replace the rechargeable batteries. Keep the range meter in a safe place. 6.2.2 Fast battery charging The charging process ensures that within 15 minutes of charging with the PDAW 80/81-2 car battery plug the battery receives enough power for a further 150 to 200 measurements. This process in combination with car battery plug is a particular advantage if the user needs the range meter ready for use quickly. 6.3 Switching the range meter On and Off The range meter is switched on or off by pressing the "On / Off" key. After being switched on, the range meter is in the basic display mode.

7.1.4 Function keys Calculation functions are activated by pressing the relevant function keys. When a measurement using a function has been carried out incorrectly or unintentionally, the function can be reset at any time by pressing the same function key again or any other function key. Volume activates the "volume" function and deactivates every other function. Area activates the "area" function and deactivates every other function. Plus activates the "distance addition" function and deactivates every other function. Minus activates "distance subtrac tion" and deactivates every other function.

7. Operation 7.2.2 Display illumination = Illumination key The illumination key, switches the display illumination On or Off. In the dark or in very bright light, e.g. sunlight or a strong spotlight the display illuminationhelps the user to read the display more easily. - NOTEDisplay illumination consumes additional power. If it is used frequently, a shorter battery life must be expected. 7.3 Measuring distances Distance measurements can be taken to all non-cooperating stationary targets, i.e. concrete, rock, wood, plastic, paper, etc., The use of prisms or other strongly reflecting targets is not permitted and, if used, might falsify the results. 7.3.1 Measuring references = switch key The range meter can measure distances from three different measuring reference points. By pressing the "switch" key on the left at the front of the range meter the measuring reference point toggles between front edge and rear edge. If the spike is folded out 90, the reference position is set to the end of the spike. Display Reference position Front edge Rear edge End of spike
- NOTE If the spike is folded out 180, reference point is always automatically set to the rear edge. 7.3.2 Measuring distances step by step The range meter measures distances in a very short time and, when doing so, shows various information in the display. 1. Switch on the range meter by pressing the "On" key.

7. Operation 7.3.4 Measuring from corners The spike is used when measuring diagonally across rooms or from inaccessible corners. 1. Fold out the spike 90. This automatically sets the measuring reference to the end of the spike. The range meter takes the extended reference point into account and corrects the measured distances accordingly. 7.3.5 Measuring with the aid of target objects When taking measurements to exterior corners, e.g. on buildings, perimeter fences, etc., boards, bricks or other suitable objects can be used as the target. Use of the PDA50 target plate is recommended for long distances and in unfavourable light conditions, e.g. strong sunlight.
2. Position the range meter with the spike at the desired starting point for the measurement and aim towards the target.
3. Press the "Measure" key. The measured distance will appear in the display.
7.3.6 Measuring in bright surroundings For long distances and bright light conditions, we recommend the use of the PDA 50 target plate.
7. Operation 7.3.7 Taking measurements to rough surfaces When measuring to rough surfaces, e.g. coarse render, stucco, etc, an average distance value is measured weighting the centre of laser spot higher that the edges of the laser spot. 7.3.10 Taking measurements to transparent surfaces It is not possible to measure distances to transparent materials, e.g. liquids, foam polystyrene, etc. This is because light penetrates these materials and therefore measuring errors may occur. If measurements are taken through glass, measuring errors may also occur.
7.3.11 Measuring ranges 7.3.11.1 Increased distances Taking measurements in the dark, at dawn, dusk and to shaded targets or with the front of the range meter, shaded generally leads to an increase of the measuring range. Taking measurements to the PDA 50 target plate also results in an increase of the measuring range. 7.3.11.2 Reduced distances Taking measurements in very bright ambient light, e.g. in sunshine or a very bright spotlight etc, can lead to a reduced distances. Taking measurements through glass or other objects in the target beam can lead to a reduced measuring range. Taking measurements to matt green, blue or black, wet or shiny surfaces can lead to a reduced measuring range.
7.3.8 Taking measurements to round or inclined surfaces If surfaces of this kind are aimed to an obtuse angle, inadequate light energy or, when aimed perpendicular, measurements may refer to the reflected laser spot from elsewhere. In both cases we recommend the use of the PDA 50 target plate 7.3.9 Taking measurements to wet or shiny surfaces As long as the range meter can be aimed towards the surface, a distance to the target will be reliably measured. In the case of highly reflective surfaces, a reduction in the range or a measurements to the actual light reflex from elsewhere must be expected.

8. Applications

8. Applications and calculation functions
The individual steps within all functions are mostly supported, on principle, by graphics on the display. - NOTE Continuous measurement can be used within all functions with where single measurements are possible. If measuring errors occur during continuous measurement or if continuous measurement is stopped by pressing the "Measure" key again, the last valid distance will be shown. 8.1 Measurement data memory While measuring, the range meter continuously saves the measured values and the results of calculations. 8.1.1 Saving measurements When measuring several distances, up to three previous distances are displayed in the intermediate result lines. This means that in total the last four measured distances are displayed or saved.
4. measured value 3. measured value 2. measured value 1. last measured value
8.1.2 Historical data memory The range meter saves the last five measurements or calculation including the graphics. Immediately after the range meter is switched on, before any function is activated or before the Measure key is pressed, these data can be recalled from the memory and displayed one by one using the"Plus / Minus" key. Example of the display of a saved volume measurement:
8.2 Area measurement Areas can be determined easily and quickly. Press the "Area" function key. This switches the laser beam on ready for measuring.
The individual steps for determining an area are supported by a corresponding graphic display. To determine the floor space of a room, for example, the following procedure must be followed:
8. Applications 1. At the start of the area function, the laser beam is switched on. 2. Aim the range meter at the target. 3. Press the "Measure" key. The room width will be measured and shown. 4. After this, the graphic display will automatically request measurement of the room length. 5. Aim the range meter at the next target to obtain the room length. 6. Press the "Measure" key. The second distance will be measured, the area immediately calculated and the result shown in the result line. The individual steps for determining a volume are supported by a corresponding graphic display. To determine the volume of a room, for example, the following procedure must be followed: 1. At the start of the volume function, the laser beam is switched on. 2. Aim the range meter towards at the target. 3. Press the "Measure" key. The room width will be measured and shown. 4. After this, the graphic display will automatically request measurement of the room length. 5. Aim the range meter at the next target to obtain the room length. 6. Press the "Measure" key. The room length will be measured. 7. After this, the graphic display will automatically request measurement of the room height. 8. Aim the range meter at the next target to obtain the room height. 9. Press the "Measure" key. The room height will be measured, the volume immediately calculated and the result shown in the result line.

Both distances required to calculate the area appear in the intermediate result lines and can be conveniently noted after the measurements and the calculation. - NOTE To determine another area, press the "Area" function key again until the graphic symbol for Area appears. 8.3 Volume measurement Volumes can be determined in one measuring operation. Press the "Volume" function key. This switches the laser beam on ready for measuring.
All three distances required to calculate the volume appear in the intermediate result lines and can be conveniently noted after the measurements and the calculation. - NOTE To determine another volume, press the "Volume" function key again until the graphic symbol for Volume appears.
8. Applications 8.4 Adding distances Single distances can be conveniently added. This is useful for determining door or window openings or to add several partial distances form the perimeter. This procedure can be repeated until all distances have been added. To terminate the addition of distances, simply measure a distance without first pressing the "Plus" key. The previous three measurement and calculation results will be in the intermediate displays. 8.5 Subtracting distances Single distances can be conveniently subtracted from each other. This is useful for determining, for example, offsets to inaccessible places or the distance from the underside of a pipe to the ceiling. To do so, the distance from the floor to the underside of the pipe is subtracted from the distance from the floor to the ceiling. If, additionally, the pipe diameter is deducted, the result is the distance from the top of the pipe to the ceiling.
