2. Description

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.

26

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.
		en
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.

2.11PUA 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).

29

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 non conductive plastic grip. The en 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).
