Fig.2 Measurement of standard transmitter proofreading

When standard transmitter output the signal at Fig.1 standard photodiode output become io=5µAp-p under the

measurement condition Fig.2.

(The radiant intensity of standard transmitter : 50mW / sr)

RPM-302B : standard photodiode has short current Isc=27µA at E=1000(lx)

(using CIE standard light source A)
