To switch on the laser beam, lightly press the measurement button 7
in the middle or press at the side.

Aim at the target.
Do not point the laser beam at persons or animals.

To measure, press the measure button 7 completely down.
The measured value appears after 0.5 to 4 s. The end of the measure-
ment is indicated by an acoustical signal. The duration of the measure-
ment is dependent on the distance, light conditions and reflection charac-
teristics of the measured surface. After completion of the measuring
procedure, the laser switches off automatically.
Continuous Pointer Mode
The unit can be switched to continuous laser beam (continuous pointer
mode) as required. For this purpose, press the somewhat recessed con-
tinuous pointer mode button
switched on between the measurements in this setting. For measuring,
only a single complete pressing down of the measurement button 7 is
necessary.
Do not look into the laser beam.

Do not point the laser beam at persons or animals.

To switch off the continuous laser beam, press the continuous pointer
mode button
unit is again in the normal mode (the laser beam is switched on only when
the measurement button 7 is pressed).
Working Instructions
The instrument measures from the back end of the case.
–
The receiving lens and the outlet of the laser beam should not be cov-
ered during a measurement.
–
Do not move the instrument during a measurement (Exception: Con-
tinuous measurement function including minimum/maximum meas-
urement). If possible, rest the instrument on or against the measuring
point.
–
The measurement takes place at the middle point of the light spot,
also for obliquely illuminated target surfaces.
–
The measuring range is dependent on the light relationships and the
reflection characteristics of the measured surface. For working in ex-
terior areas and with strong direct sunlight, use the optical sight ZO 4
31, the laser viewing glasses 28 and the target panel 29 (accessory)
for better visibility of the laser point or shield the target surface.
–
When measuring to transparent surfaces (e.g. glass, water) or reflect-
ing surfaces, erroneous measurement can result. Porous or struc-
tured surfaces, air strata with different temperatures or indirectly re-
ceived reflections can also influence the measured value. These
effects are caused by physical properties and can therefore not be ex-
cluded by the measuring instrument.

When the unit is switched off, all values stored in memory are re-
tained. However, when the end piece is removed (changing of the
end piece or the batteries), the memory contents are lost.
