1. Product information

Description of functions, continued

The point from which the measurement is taken is clearly identified by the red spot. The range of the tool depends on the reflectance and surface finish at the point where the measurement is taken. The reference point on the tool can be selected for different types of measurements.

Distances between 0.3 and 30 m

-Target the object directly.

-Use the white target plate.

Distances between 30 and 100 m

- Use the brown target plate.

Features

-Compact and functional design

-Simple, self-explanatory menu selection and menu settings

-One-man, hand-held operation for speed of use

-Large display (can be illuminated)

-Memory function for constants

-Built-in calculator functions

-Pythagoras button for rapid calculation of building heights

-Switches off automatically

-The last three measured values remain in memory

-Built-in bubble level

-Tripod mounting threads

Typical measuring range without target plate

Drywall panel, white	60 m
Concrete, dry	50 m
Brick, dry	50 m

*Maximum range depends on reflectance of the target surface and on the brightness of ambient light. If difficulty is experienced (no measurement possible), the Hilti PA411 target plate should be used.
