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.
