B. Detection Length Test

C. Pulse Width Test

NOTE 1. Distance between emitter & detector specifies maximum distance that output wave form satisfies

the standard under the conditions below against the standerd transmitter.

(1)Measuring place ………Indoor without extreme reflection of light.

(2)Ambient light source… Detecting surface illumination shall be 200±50Lux under ordinary

hite fluorescense lamp of no high frequency lighting.

(3)Standard transmitter … Burst wave indicated in Fig 1. of standard transmitter

shall be arranged to 50mVp-p under the measuring circuit

specified in Fig 2.
