*2 Defines EV= 50l x (IS485 ) and E V= 0 (IS486 ) .
*3 Defines EV= 0 (IS485) and E V= 50l x (IS486 ) .
*4 E VHL represents illuminance by CIE standard light source A(tungsten lamp) when output changes from high
to low.
*5 EVLH represents illuminance by CIE standard light source A(tungsten lamp) when output changes from low
to high.
*6 Hysteresis stands for EVLH /E VHL (IS485 ) and E VHL /E VLH (IS486 ) .
