1309 are easy to use with pocket size and light weight, providing
accurate display light level in terms of Foot Candles (FC) or LUX over wide range.
Just turning the Function Switch to select the “lux” scale and setting the range to
desired range, then removing the photo detector to light source in a horizontal position
and reading the illuminance norminal from the LCD display. When the measurement
is completed, replace the photo detector from the light source.
Widest range to 40,000Fc/
