Measuring Ranges: 0 to 300, 0 to 1,000 and 0 to 3,000 lx (switch selectable)
Accuracy: ±7% of reading (23 deg. C ± 2 deg. C)
Photocell: Selenium cell with plastic molding.
Photocell Lead: Approx. 1.1 m (3.6 ft) long.
Cosine Correction: Angular errors of light incidence on the cell are corrected by the globe covered on photocell (with spectral transmission characteristics).
