Illuminance measuring

Function	Range	Resolution	Accuracy tolerance: ± ( a %reading +b digits)
Illuminance measuring (LUX)	20Lux	0.01Lux	± (3% + 20)
	200Lux	0.1Lux	± (3% + 8)
	2000Lux	1Lux	± (3% + 8)
	20000Lux	10Lux	± (3% + 8)
Illuminance measuring (FC)	2FC	0.001FC	The accuracy tolerance of FC can be verified by unit conversion: FC = 10.76lux, if accuracy tolerance verification is needed, it can be achieved by unit conversion.
