*2 Defines EV = 50lx( IS487 ) and E V = 0 ( IS488 ) .
*3 Defines EV = 0 (IS487) and E V = 50lx ( IS488 ) .
*4 EVHL represents illuminance by CIE standerd light source A ( tungsten lamp) when output changes from high
to low.
*5 E VLH represents illuminance by CIE standerd light source A (tungsten lamp) when output changes from low
to high.
*6 Hysteresis stands for EVLH /E VHL ( IS487 ) and E VHL /E VLH ( IS488 ) .
