As of May 1997

*1 • Dust density is measured by mildseven smoke density, using digital dust meter [P-5L2 made by

SHIBATA scientific instrumental industry].

• Detecting sensitivity is settled according to the change of output voltage when dust density change

*2 Input conditions to LED terminal (pulse operation condition) is shown in the right figure.
