with explosive gas (material), combustible gas
(material) steam or filled with dust.
zIn order to avoid reading incorrect data, please
replace the battery immediately when the symbol
“” appears on the LCD.
zIn order to avoid the damage caused by
contamination or static electricity, do not touch the
circuit board before you take any adequate action.
zOperating Environment: Indoors use. This
instrument has been designed for being used in an
environment of pollution degree 2.

3. Preface
The flux of light received in a unit area of a certain side
being show is popularly known as illumination. In both
United Kingdom and America its unit is known as
footcandles light, but in Europe it is known as meter
candlelight.
One foot-candles light is the illumination of light that
falls on one side that lies in a distance one foot away
from a one foot-candlelight and exactly intersecting the
light. 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.
1 FC=10.764 LUX, 1 LUX=0.09290 FC,
therefore,Nbr. of foot (meter) candlelight =
Nbr. of Lumen
