H-resolution mode2 is 0.5lx ( typ. ) resolution mode. It is suitable if under less than 10 lx measure ment data is necessary.
This measurement mode supports " Adjust measurement result for influence of optical window ". Please refer it. It is possible
to detect min. 0.11 lx by using H-resolution mode2.
○ Instruction set architecture for H-resolution mode2
○ Measurement sequence example from "Write instruction" to "Read measurement result"
ex) Continuously H-resolution mode2 ( ADDR = 'L' )
① Send "Continuously H-resolution mode2 " instruction
② Wait to complete 1st H-resolution mode2 measurement.( max. 180ms. )
③ Read measurement result.
