6.5 Measuring references

NOTE
The tool can take measurements from 4 different ref-
erence (contact) points. The "Reference" button on the
left on the front of the tool is used to switch between
the front and rear references (front or rear edge of the
tool). The reference is set automatically to the tip of the
spike when the spike is folded out through 180°. When
the measuring extension is screwed into place, this is
detected automatically by the tool and indicated by the
long extension symbol in the display.

6.6 Measuring distances

NOTE
When the spike is folded back in, the measuring reference
is always reset to the rear edge of the tool irrespective of
how far the spike was folded out or to which point on the
tool the measuring reference was previously set.
Distances can be measured from all stationary targets
without a highly reflective surface, i.e. concrete, stone,
wood, plastic, paper, etc. The use of prisms or other
highly reflective targets is not permissible and, if attemp-
ted, may falsify the results.

----------
Press the "Measure" button once. The laser beam is

the target surface. This aiming mode is indicated in the
display by a blinking laser symbol.
