Special functions
If desired, the sides of an Area/Volume can be
composed of several partial lengths. Select the
AREA/VOLUME function.
Press the PLUS - key {A, 3} or MINUS - key {A, 11}
before you start with the first partial measurement.
Proceed with the first partial measurement by pres-
sing DIST - key {A, 1}. In the display an addition or
subtraction symbol appears. Make the first partial
measurement, press PLUS - key {A, 3} or MINUS -
key {A, 11} and make the second partial measure-
ment. Unlimited partial measurements can be
summed up or subtracted. To finish the distance
measurement press the EQUAL - key { A, 5}. The
second distance can be made up of partial distances
with the same method. The result of the Area/Volume
calculation is displayed as usual in the summary row.

Indirect Measuring

The instrument can measure vertical distances with
the tilt sensor. This procedure is especially helpful if
the upper target point does not reflect the laser. The
upper target point can be aimed at, with the digital
viewfinder. For a double tilt measurement, the first
measurement only requires a tilt measurement and
not a distance measurement.
Then the vertical and horizontal distances can be
calculated with the Pythagorean theorem. This
method is ideal when the distance to be measured is
hard to reach.

•

Both methods only serve to estimate distances
and cannot replace an exact measurement.

•

Make sure you adhere to the prescribed sequence
of measuring.

•

All target points must be in a straight line to the
wall area. See figure {N, P}

•

Best results can be expected if the device is
turned around a fixed point (e.g. positioning
bracket folded out completely and the device is
held towards a wall)

•

It is highly recommended to use the "Minimum/
maximum measuring" by pressing the DIST -
key {A, 1} longer. The minimum value is used for
the measurements perpendicular towards the
target respectively the maximum value for the
other measurements. This increases the accuracy
of the indirect measuring considerably.

Indirect single tilt measurement - determine
all 3 sides and an angle with 1 distance mea-
surement

See figure {M}
Press the INDIRECT MEASUREMENT - key {A, 12}. In
the symbol, the distance to be measured is high-
lighted. Make the required distance measurement.
The result is displayed in the summary row, the
measured distance and the angle in the secondary
row.
Press the INDIRECT MEASUREMENT - key {A, 12}
for a longer period to obtain more details.
