2. Description

2. Description

The distance is determined along a laser
beam emitted by the range meter up to the
surface where the laser beam is reflected.
The red laser spot clearly identifies the tar­get from which the measurement is taken.

The measuring range depends on the
reflectivity and the surface structure of the
target surface.

2.1 Intended use

The range meter is designed for:
– Measurement of distances
– Calculation of areas, volumes and distances
– Addition and subtraction of distances
– Operation and storage in the specified

temperatures

2.2 Items supplied

1 PD 38 laser range meter
1 PDA 50 target plate
1 PDA 60 hand strap
1 PDA 66 holder

1 operating instructions
1 producer certificate

2.3 Measuring principle

The range meter emits a visible laser beam
carrying a wave signal which is reflected
and received with a phase shift. The phase
shift is used to determine the distance.
This measuring principle permits highly
accurate and reliable distance measure­ments to objects without use of special
reflectors.

3.1 PDA 50 target plate

The PDA 50 target plate is made of durable
plastic with a special reflective coating. In
poor light conditions it is advisable to use
the target plate for distances above 10 m
(30 ft).

-NOTE-

– For reliable distance measurements the

laser beam should be perpendicular to
the target plate whenever possible. If this
is not the case, the laser spot on the tar­get plate may not be in the same plane
as the target point and the distance
measured will be incorrect.

– For very accurate measurements using

the target plate, 1.2 mm (1/20 inch)
should be added to the measured dis­tances.

3.2 PDA 80/81 charging kits

The PDA 80 and PDA 81 charging kits
enable use of the range meters with
rechargeable cells. Battery charging time is
approx.12 hours for fully discharged cells.
However, within the first 15 minutes, the
cells are charged with sufficient current for
150–200 measurements.

Please also refer to the description of bat­tery charging in section 6. “Getting start­ed”.

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 suit-

able prior instruction.

– Do not render any safety devices ineffec-

tive 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.

– Tampering with or modification of the

range meter is not permissible.

– Use only genuine Hilti accessories and

auxiliary tools in order to avoid the risk
of injury.

– Do not use the range meter in atmos-

pheres 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 condi-

tions, 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.

– 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 re-

ference 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, as
with other optical instruments (binocu­lars, spectacles, cameras, etc.) it should
be treated with care.

– 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.

– When using the circular bubble level

(bull's eye) for alignment, only look at
the range meter from the side.

5. Safety information

5.4 Proper organization of workplace

– Secure the area in which you are measur-

ing. When setting up the range meter,
take care to avoid directing the beam
toward yourself or other people.

– Avoid unfavourable body positions 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, stainless
steel, polished stone, etc.

– Observe the accident prevention regula-

tions applicable in the country in which
you are working.

– Use the PDA 66 holder only together with

the PDAs/MDAs recommended by Hilti
and only in conjunction with the PD 38.

– Check to ensure that your PD 38 com-

municates only with your PDA/MDA, and
vice versa.

5.4.2 Laser classification

The range meter conforms to laser class 2
based on the IEC60825-1: 2003; standard
and class II based on CFR 21 § 1040
(FDA). These range meters may be used
without need for further protective meas­ures. The eyelid closure reflex pro tects 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.

based on CFR 21 § 1040 (FDA)

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 interfer-

ence 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.

6. Getting started

6.1 Inserting alkaline/rechargeable
batteries

-CAUTION-

– Observe the polarity of the batteries.

(refer to symbols inside the battery com­partment.)

– Make sure the battery compartment is

properly locked.

1.Press the cover of the battery compart­ment lightly.

2.Slide the cover out and off.

3.Replace the batteries.

For rechargeable batteries
– Always use rechargeable batteries of the

same make and same type.

same age and charged to the same level.

– New rechargeable batteries are supplied

uncharged and have to be charged prior
to first use.

– Use only 1.2 V NiMH batteries with

1500–2000 mAh capacity.

6.2 Battery charging

6.2.1 Standard battery charging

The charging process ensures that there
will be virtually 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 adapter
to the range meter

.

For charging, connect either the mains
adapter or the car battery plug  to the
charging adapter.

-NOTE-

For alkaline batteries
– Always replace a complete set of batter-

ies.

– Do not mix used and new batteries.
– Do not mix batteries of different makes

or types.

– Use only undamaged batteries of an

approved type.

6.2.1.2 Charging display for unintention-

ally inserted alkaline batteries

– If alkaline batteries are identified, all bat-

tery status segments flash continually to
indicate missing rechargeable batteries.
Additionally, the symbol

Accuno

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,

appear in the display.

-NOTE-

– The range meter can be switched on and

used at any time while the batteries are
being charged. 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 deeply dis­charged or defective rechargeable batter­ies and the display switches off. In this
case, the charging process can be re­started only by disconnecting the range
meter from the mains adapter or by
removing/replacing the rechargeable bat­teries.

– Keep the range meter in a safe place.

6.2.2 Fast battery charging

The charging process ensures that 15 min­utes of charging with the PDAW 80/81-2
car battery plug provides the battery with
enough power for a further 150 to 200
measurements.
This process in combination with the car
battery plug is of particular advantage in
situations where the user needs the range
meter ready for use quickly.

6.3 Switching the range meter on and off

7.2.2 Display illumination

= Illumination button

The illumination button switches the dis­play illumination on or off. In the dark or in
very bright light, e.g. sunlight or a strong
spotlight, the display illumination makes it
easier to read the display.

-NOTE-

Display illumination consumes additional
power. If it is used frequently, shorter bat­tery life must be expected.

7.3 Optical sight

The built-in optical sight is of great benefit
when measuring outdoors and whenever
the laser spot is poorly visible. The optical
sight allows the laser spot to be positioned
on the target accurately even at great dis­tance. The laser spot is visible in the opti­cal sight when the range meter is switched
on. If the laser spot is not visible in the
optical sight then either the measurement
has been completed successfully or the
laser beam has switched itself off automat­ically after the preset time (1 minute).
The optical axis of the sight runs parallel to
the laser beam.

Typical measuring procedure with the
optical sight

– Press the “Measure” button to activate

the laser beam.

– Use the optical sight to aim the range

meter and position the laser spot on the
target.

– Press the measure button or side mea s-

ure button and keep the laser spot on the
target until the spot disappears from the
optical sight.

– Read the distance from the display.

7.4 Measuring distances

Distance measurements can be taken to all
stationary targets without a highly reflec­tive surface, i.e. concrete, rock, wood,
plastic, paper, etc. The use of prisms or
measuring to highly reflective surface is
not permitted and, if attempted, might fal­sify the results.

7.4.1 Measuring references

= Reference button

The range meter can measure distances
from three different measuring reference
points.
The measuring reference point can be tog­gled between the front edge and rear edge
by pressing the reference button on front
left of the range meter. The reference is set
automatically to the end of the spike when
the spike is folded out to the 90° posi tion.
The reference can be set to the end of the
PDA 70 measuring reference extension by
pressing the reference button (top left) and
the on/off button (top right) simultaneously
while the range meter is switched off. The
spike symbol in the display then begins to
blink.
This measuring reference setting for the
PDA 70 can be deactivated by switching
the range meter off and then on again.

7.4.3 Measuring mode

Two different distance measuring modes
are available. These are single distance
mea surement and continuous distance
measurement. The continuous measure­ment mode is used for setting out given
distances or offsets and is also used where
distance measurements are more difficult,
e.g. to corners, edges, niches, etc.

7.4.3.1 Single distance measurement
(“Measure ”)

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

2.Press the “Measure” button once again.
The measured distance will normally be
shown in the result line in less than a
second.

-NOTE-

Alternatively, the range meter may be
switched on by pressing the “On” button
and the laser then activated by pressing the
“Measure” button.

7.4.3.2 Continuous measurement

Press the “Measure” button for about
2 seconds to activate this measuring mode.
When doing so, it does not matter whether
or not the range meter or the laser beam is
switched on or off. The range meter will
always switch to continuous measurement.
During continuous measurement, distances
are updated in the result line at the rate of
about 8 to 15 measurements every second.
The rate of measurement depends on the
reflectivity of the target surface.
If the beep signal is active, continuous
measurement is indicated by a beep.
The measuring process is stopped by
pressing the “Measure” button once again.
On doing so, the last valid distance meas­urement will be shown in the result line in
the display.

-NOTE-

Continuous measurement is possible in all
situations where distances can be mea s­ured. This applies also to functions, such
as areas and volumes.

7. Operation

7.4.4 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.

2. Position the range meter with the spike

at the desired starting point for the
measurement and aim towards the tar­get.

7.4.5 Measuring with the aid of target
objects

When taking measurements to outside cor­ners, e.g. on buildings, perimeter fences,
etc., boards, bricks or other suitable
objects can be used as the target.

Use of the PDA 50 target plate is recom­mended for long distances and in unfa ­vourable light conditions, e.g. strong sun­light.

3. Press the “Measure” button. The meas-

ured distance appears in the display.

Printed: 07.07.2013 | Doc-Nr: PUB / 5070015 / 000 / 00

7.4.6 Measuring in bright conditions

The PD 38 has a built-in optical target
sight. When measuring to very bright sur­faces, the laser spot is often not visible.
Thanks to the laser spot superimposed in
the optical sight, you can always clearly
and reliably aim at the target.
We recommend use of the PDA 50 target
plate for long distances and bright light
conditions.

19

7. Operation

7.4.7 Taking measurements to rough sur-

faces

When measuring to rough surfaces, e.g.
coarse render, stucco, etc, an average dis­tance value is measured with the centre of
laser spot weighted higher than the edges
of the laser spot.

7.4.8 Taking measurements to round 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 range meter in certain situa­tions where the laser beam strikes the tar­get perpendicularly.
We recommend use of the PDA 50 target
plate in both of these situations.

7.4.9 Taking measurements to wet or

shiny surfaces

As long as the range meter can be aimed
towards the surface, the distance to the
target will be reliably measured. In the case
of highly reflective surfaces, a reduction in
range or measurement of the distance to
the actual point of reflection must be
expected.

7.4.10 Taking measurements to transpar­ent surfaces

It is not possible to measure distances to
transparent materials, e.g. liquids, poly­styrene foam, etc. This is because light
penetrates these materials and therefore
measuring errors may occur. Measuring
errors may also occur if measurements are
taken through glass or if obstructions are
present within the line of the laser beam.

7.4.11 Measuring ranges

7.4.11.1 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 in the measur­ing range.

– Taking measurements to the PDA 50 tar-

ge t plate also results in an increase in the
measuring range.

7.4.11.2 Reduced distances

– Taking measurements in very bright

ambient light, e.g. in sunshine or a very
bright spotlight etc, can lead to a reduc­tion in range.

– Taking measurements through glass or

other objects in the target beam can lead
to reduced measuring range.

– Taking measurements to matt green, blue

or black, wet or shiny surfaces can lead
to reduced measuring range.

8.1 Measurement data memory

The range meter continuously saves the
measured values and the results of calcula­tions while measuring.

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.

8.5 Subtracting distances

Individual 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.

10. PDA/MDA Windows CE with Hilti PD 38 application

10. PDA/MDA Windows CE with
Hilti PD 38 application

The Hilti PD 38 application is installed on a
PDA/MDA as described in chapter “9.1.2
Installation of Hilti PD 38 application soft­ware on a PDA/MDA”. The program con­tains four major functions, Image Sketch,
Line Draw, Data Table and Formu lary. The
measurements are transferred to the partic­ular function by wireless communication –
all measurements can also be entered
manually.

-NOTE-

Further instructions about the separate
functions can be found in the help texts for
the particular function on the PDA/MDA.

1. “Image Sketch”
Some PDAs and most MDAs are equip ­ped with a digital camera which allows
photos to be taken of a particular object
on the spot, e.g.window, door, room, etc.
Existing digital images can also be trans­ferred to the PDA/MDA. Measured
lengths, shown as lines with dimensions,
can be added directly to the photos
taken on the spot with the PDA/MDA or
those transferred from the PC.
These photos with measurements can
then be printed out or transferred to the
PC for further use.
Using an MDA, the photos can be sent
as an E-mail from the photo location, for
example, to an office.

All relevant output formats, e.g. bitmap
(*.bmp) or JPEG (*.jpg) can be trans­ferred to the PC.

2. “Line Draw”
This drawing function creates outline
plans – combining measuring and scale
drawing – on the spot.
Other possible uses are the design and
drawing of non-rectangular objects and
features.
The calculation of the area of enclosed
geometrical figures is also possible, even
when several are joined together.

All common CAD output formats are
supported for transfer to the PC

– Felixcad (*.flx)
– AutoCad DXF (*.dxf) for release 12 up to

release 14 and AutoCad 2000/2002

– AutoCad Format (*.dwg) for release 12

up to release 14 and also AutoCad
2000/2002

All drawings can also be transferred as
pixel data to the PC

– Bitmap (*.bmp)
– JPEG (*.jpg)
This allows the drawings to be displayed
on a PC without a CAD system.

3. “Data Table”
The Data Table function creates a table fully
compatible with Windows Excel, with
measurements entered directly in the
appropriate cells.
However, measurements are activated
(from the PDA/MDA or from the PD 38)
only when the “Hilti Measuring Interface”
in the lower right-hand window has been
activated.
Once active, the symbol is shown in
the lower section of the PDA/MDA display.

-NOTE-

Take note of the units used in Excel as
these are not saved.

10. PDA/MDA Windows CE with Hilti PD 38 application /11. Data transfer from PDA/MDA to PC

Different options exist when using the
data table

– The data table can be used with the cells

simply containing measurements, with­out any line or column description.

– The structure of the table can be estab-

lished on the PDA/MDA, i.e. the lines and
columns are pre-defined according to the
measurement needs and the measure­ments entered into the respective cells.

– The structure of the table can be defined

and established in Windows Excel on the
PC, i.e. a relevant structured measure­ment table fully pre-defined on the PC.
This can also contain formats and formu­las which can be used as checks on the
spot.

-NOTE-

Measurements initiated from the PD 38 are
displayed on the PDA only when the Hilti
Measuring Interface is active.

On completion of the measurements, the
table can be transferred to the PC for fur­ther use.

4. “Formulary” .
The functions of the formulary serve to
assist with less common measuring
tasks, e.g. measuring length at inacces­sible places, angle and area determina­tions of non-rectangular areas and much
more …

Measurements are transferred directly to
the relevant location within the function.
Measurements can also be entered man­ually. The user is guided step by step by
the graphical user interface.

List of functions:
– Area computations
– Volume computations
– Indirect distance measurement using

Pythagorean function (3 options)

– Circle computations

(area and circumference)

– Inclination computations (roof slope,

pipe slope, etc … in inaccessible places)

– Minimum and maximum measurements

for diagonals and much more

– Average computations from eight con-

secutive measurements

Computation results can be copied for fur­ther use in other programs, as far as this
option exists.

11. Data transfer from
PDA/MDA to PC

Data is transferred between the PDA/MDA
and the PC using the Windows Active Sync
software. It is essential that Active Sync is
previously installed on the PC and a con­nection established between the PDA/MDA
and the PC.
The exchange of data files between the PC
and PDA/MDA is carried out using the
“Copy” and “Insert” functions.

The data must be saved in the correct for­mat before it can be transferred from the
PDA/MDA to the PC.
– Data from “Image sketch” must be saved

in an appropriate folder in the *.bmp or
*.jpg format.

– Data from “Line draw” must be stored in

one of the many optional data formats.

– Data from “Data table” is already saved

in the Windows Excel *.xls format.

11. Data transfer from PDA/MDA to PC/12. Calibration and adjustment

Example of data transfer from PDA/MDA to
PC

1. Place the PDA/MDA in the docking sta­tion and switch it on.

2. For access to the data memory in the
PDA/MDA select “File” and then
“Search” in the Active Sync window.

3. The complete contents of data memory
in the PDA/MDA are then displayed.

4. Select the applicable folder and then the
file to be transferred to the PC.

5. Mark the file and then select “Copy”.

6. Select the applicable PC drive, e.g. drive
“C:” from the bar at the top of the Active
Sync window.

7. Then select the folder on the PC drive
into which the file from the PDA/MDA is
to be transferred.

8. Select “Insert” and the applicable file
will then be transferred from the PDA/
MDA to the PC.

The procedure for transferring data from
the PC to the PDA/MDA is very similar, the
main difference being that the file is first
selected on the PC before being transferred
to the PDA/MDA.

12. Calibration and adjustment

12.1 Calibration

Inspection and testing of the range meter
for users (companies) certified in accor­dance with ISO 900X...

You may carry out the inspection, and test­ing of the PD 38 laser range meter as
specified in ISO 900X... by yourself. (See
ISO 17123-4 Field Process for Accuracy
Examinations of Geodetic Instruments:
Part 6, Close-range Opto-electrical Range
Meters.)

Select a readily accessible measuring dis­tance of a known length approx. 1 to
5 meters (3–15 ft) long which does not
vary with time and take five measurements
of the same distance.

Determine the mean of the deviations to
the known distance. This value should be
within the specific accuracy tolerance for
the range meter.

Keep a record of this value and note the
time for the next test.
Repeat this check measurement at regular
intervals as well as before and after impor­tant measuring tasks.
Apply a sticker to the PD 38 documenting
this control of the measuring, inspection
and test equipment for the range meter and
keep a record of the entire control process,
inspection procedure and the results.
