Preparation
Inserting/Replacing the Batteries
AAA Alkaline batteries are recommended for the measuring tool.
To open the battery lid 3, press the latch 4 in the direction of
the arrow and remove the battery lid. Insert the batteries. When
inserting, pay attention to the correct polarity according to the
representation on the inside of the battery compartment.
When the battery symbol appears for the first time on the
display, measurements are still possible for approx. 15 minutes.
When the battery symbol flashes, the batteries must be
replaced; measurements are no longer possible.
Always replace all batteries at the same time. Only use
batteries from one brand and with the identical capacity.
Remove the batteries from the tool when not using it for
extended periods. When storing for extended periods, the
batteries can corrode and discharge themselves.
Laser class 2
Laser type 635 nm, <1mW
Laser beam diameter 77° F (at 25 °C)
and at 30 ft (10 m) distance, approx. 3/8 in (9 mm)
and at 50 ft (15 m) distance, approx. 1/2 in (13.5 mm)
Batteries 2 x 1.5V (AAA)
Battery service life in measuring operation, approx. 5 h
Weight 0.2 lb (0.1 kg)
Dimensions 4 x 1.4 x 0.9 in (100 x 36 x 23 mm)
A) The working range increases depending on how well the laser light is reflected from
the surface of the target (scattered, not reflective) and with increased brightness of
the laser point to the ambient light intensity (interior spaces, twilight). In unfavorable
conditions, e.g., with extreme interior illumination or a badly reflecting surface, the
measuring range may be limited.
B) In unfavorable conditions, e.g., with extreme interior illumination, badly reflecting
surface or the room temperature deviating heavily from 77°F (25°C), the maximum
deviation can be up to ±7 mm per 15 m. In favorable conditions, a deviation influence of
±0.05 mm/m must be taken into account.
The measuring tool can be clearly identified with the serial number 5 on the type plate.
