Gross errors appear through nonattation
by reading the measure. So it can be that number turners (32-23) or meter
error (1m, 20m, 50m) occur. You can check measurements e.g. to measure
struts or to make a second measurement. By
measure a strut (9,45m) we can controll the measured building walls. For
controlling we use the "theorem of Pythagoras" (a² + b² = c²).
In this case 7,98m stands for A and 5,07m for B. If the calculated
C and the measured C do not correspond, a number turner could
also be responsible for it! |
