1) Maximum deviation error or shorter range occurs under unfavourable conditions such as
bright sunlight or when measuring too poorly reflecting or very rough surfaces, the
environment temperature is too high or too low.
2) When measuring within 10m, measurement accuracy is ±2mm; more than 10m,
measurement accuracy is calculated as follows: ±2mm±0.05*(D-10)(D: measuring distance,
unit: m).
