1. Instruction
This digital light meter is a precision instrument used to measure illuminance in the
field. It is totally cosine corrected for the angular incidence of light.
The light meter is compact, tough and easy to handle due to its construction. The
light sensitive component used in the meter is a very stable, long life silicone diode.
2. Features
* Light-measuring levels ranging from 0.1Lux to 200,000 Lux,
0.01 FC to 20,000 FC repeatedly
* High accuracy and rapid response
* Peak-Hold function for holding measuring values
* Unit and sign display for easy reading
* Automatic zeroing
* Meter corrected for Luminous Efficiency function
* The Correction factor doesn’t have to be manually calculated for non-standard light
sources
* Short rise and fall times
