Notice:
There are four frequently used PRR: 300KHz, 500KHz, 750KHz and 1000KHz. For
example, If scanner works as 300KHz: when the object reflectivity
≥
10%, the maximum
measuring range is only 150m; And when the object reflectivity
≥
80%, the maximum
measuring range is 420m. So, it can be concluded that both PRR and object reflectivity will
influence the maximum measuring range. When you use high PRR for scanning such as 750KHz
and 1000Khz, the maximum measuring range is highly influenced by battery level: When
scanner works as 750KHz and object reflectivity
≥
80%, the maximum measuring range is
270m under full charged condition but only 135m under low charged condition; When scanner
works as 1000KHz and object reflectivity
≥
80%, the maximum measuring range is 235m under
full charged condition but only 120m under low charged condition.
