With indirect length measurement, you can determine dis-
tance AB by measuring distance 1. The measuring tool calcu-
lates the required length AB from angle and distance 1.

With trapezoid measurement, the length of a sloping roof can,
for instance, be determined. You can determine section AB by
measuring sections 1, 2 and 3 in this order. The measuring tool
calculates the required section AB from sections 1, 2 and 3.

Wall Area Measurement
B
The wall area measurement is used to determine the sum of
3 multiple individual areas with a common height. The require-
ment for a correct area calculation is that the first measured
length (for example the ceiling height H) is identical for all sub-
areas. In the illustrated example, the total area of several walls
