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.

3. Preface
The flux of light received in a unit area of a certain side
being shown is popularly known as illumination. The
measuring unit in both United Kingdom and America is
known as footcandles light, but in Europe it is also
known as meter candlelight.
One foot-candles light is the illumination of light that
falls on one side which is one foot away from a one
foot-candlelight and exactly intersecting with 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 which is one meter away from a one meter
candlelight and exactly intersecting 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
──────────────
Area(sq. foot or sq. meter)
Nbr. of Lumen=Nbr. of foot (or meter)x area
