*1. It specifies the maxmum distance between emitter and detector that the output wave form satisfies the standard under the conditions
below against the standard transmitter.
1) Measuring place
: Indoor without extreme reflection of light
2) Ambient light source : Detecting surface illumination shall be irradiate 200±50lx under ordinary white fluorescence lamp without
high frequency lightning
3) Standard transmitter : Burst wave of standard transmitter shall be arranged to 50mVP-P under the measuring circuit
