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
