INTRODUCTION
The 61-686 meter measures visible light from LED, fluorescent, metal halide,
high-pressure sodium, incandescent and other light sources.
The foot-candle unit is defined as the amount of illumination the inside
surface an imaginary 1-foot radius sphere would be receiving if there were a
uniform point source of one candela in the exact center of the sphere.
Alterna-tively, it can be defined as the illuminance on a 1 -square foot
surface of which there is a uniformly distributed flux of one lumen. This can
be thought of as the amount of light that actually falls on a given surface.
The foot-candle is equal to one lumen per square foot.
The Sl derived unit of illuminance is the lux. One foot-candle is equal to approximately 10.764 lux, although in the lighting industry, typically this is approximated as 1 footcandle being equal to 10 lux.
OPERATING THE METER
- Press the” ” button to turn the power on or off
- Remove the sensor’s cap and place the sensor in the area to be measured.
