In such case, please point as shown in Figure 4.6.B to avoid receiving the glass reflected light.
Page 23
4.6.3 Case 3 When detecting towards the corner (or similar situation), as shown in Figure 4.8.A, the infrared laser may reflect between walls, resulting in high measurement concentration. In such case, please point as shown in Figure 4.8.B to have the accurate measurement result. Figure 4.8 Do's and Don'ts when detecting the corner - 2 0 -...
