4 Illumination Instruction

The flux of light received in a unit area of a certain
side being shone is popularly known as
illumination. In both United Kingdom and United
States, the unit is known as foot-candle light, but
in Europe it is known as meter candlelight.
The 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. Alternatively, it can be defined as the
illumination 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. Its
abbreviated form is written as 1 Fc=1 Lm/ft,
similarly,one-meter candlelight is the illumination
of light that falls on a side that lies in a distance
one meter away from a one meter candlelight and
exactly intersects the light. It is also called Lux i,e.
the flux of light being received in each sq. meter is
called the illumination of one lumen.
As one foot candle=10.764 Lux, therefore,Nbr. of
foot (meter) candlelight =Nbr. of Lumen

――――――――――――――

Area(sq. foot or sq. meter)
Nbr. of Lumen=Nbr. of foot (or meter)x area
Foot-candle/Lux conversion
1 foot-candle=10.764 lux

TM-208

1 lux=0.09290 foot-candles
(sq, foot or sq. meter)

Relative Spectral (SENSITIVITY)

The deviation from the comparative standards for
luminosity is determined by JIS standard C
1609-1993.

Typ.Ta=23°C

NOTE 1.：When the light sensor cap is not
attached on the sensor, the word “CAP” will
appear on the LCD. Make sure that the cap is

7

TM-208

attached on the sensor.If the zero adjustment has
not been made correctly, some digits will still
appear on the LCD instead of 0.00. In this case,
please make the zero adjustment again.

NOTE 2.：Light Source Luminous Intensity (cd)
calculated if a single light source is used and is
regarded as a single-point light source, the
luminous intensity of the light source can be
calculated and displayed, by setting the distance
from the light source to the measuring point.

Luminous intensity (cd) = llluminance (LUx) x
distance (m)

Set the distance to the measuring light source in
advance.
