- Page 2 Ⅰ INSTRUCTION The digital illuminance meter is a precision instrument used to measure illuminance (lux, footcandle) in the field. It is meet CIE photopic spectral response. It is fully cosine corrected for the angular incidence of light. The illuminance meter is compact, tough and easy to ...
- Page 3 Meter corrected for spectral relative efficiency. Correction factor need not be manually calculated for non-standard light sources. Short rise and fall times. Peak-hold function for tracing the peak signal of light pulse with least duration 10μs and keep it. ...

- Page 10 Ⅶ SPECTRAL SENSITIVITY CHARACTERISTIC To the detector, the applied photo diode with filters makes the spectral sensitivity characteristic almost meet C.I.E.(INTERNATIONAL COMMISSION ON ILLUMINATION) Photopic curve V (λ) as the following chart described. Ⅷ MAINTENANCE The white plastic disc on the top of the detector should be cleaned with a damp cloth when necessary.
- Page 11 The calibration interval for the photo detector will vary according to operational conditions, but generally the sensitivity decreases in direct proportion to the product of luminous intensity by the operational time. In order to maintain the basic accuracy of the instrument, periodic calibration is recommended.
