*1 • Dust concentration shall be a value of the cigarette (MILD SEVEN) smoke concentration measured using the digital dust densitometer

(SHIBATA KAGAKU KOGYO CO. LTD. made P-5L2).

• Detection sensitivity K represents the change of output voltage when dust concentration changes by 0.1 mg/m .

*2 Input conditions (pulse drive conditions) to LED input terminal shall be as shown in the right drawing.
