and best function of this device prior to using.
REFACE
Illumination:
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 America
its unit is known as foot candlelight, but in Europe
it is known as meter candlelight.
One foot candlelight is the illumination of light
which 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 which falls on a side that lies
in a distance one meter away from a one meter
candlelight and exactly intersects the light. lt is
also called Lux i,e. the flux of light being received
in each sq. meter is called the illumination of
one lumen.
A
s one foot candle=10.76 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 (sq,
foot or sq. Meter) `I .FEATURES

3. OPERATION PROCEDURE
1) Open the carrying case.
2) Turn on the Power Switch. Choose the unit of
Lux of Fc which you want to test. Then choose the
right range appropriate for testing.
3) Remove the cover of the light receiver, Put the
light receiver at the spot where the testing of source
of light i
s
to be conducted, Auto testing will then be
conducted by the meter, Read the testing value
after the reading indicated becomes stable.
4) when "OL" is shown at the highest position at the
left lateral side, overload
is
indicated, Then please
choose another range which is located at a
comparatively higher position. Attention: when
testing
is
fixed at the range of
20000Lux,50000Lux,5000Fc,the numencal value
shown by the indicator must be multiplied by 10
times or 100 times to get the true value tested.
5) If you want to keep the reading value on the LCD
permanently after testing, press the D-H Key
whereby the reading value will be locked
permanently up. Press the D-H Key once again
when you want to remove the previous locking.
6) After testing, put the cover of the light receiver
back to its former position, and turn off the switch.
7)After testing is completed, the indication value
should be 000 no matter
what its range would be after putting the cover of the
light receiver back to its former position. Please
adjust 0 ADJ to enable LCD to indicate 000 if zero
cannot be recover. If zero still can not be
recovered, lt means that the meter breaks down.
5. ATTENTION
1)In the measurement of illumination, the reading will
be caused to jump by the variance of power or the
shadow of surrounding people. The condition of the
surrounding temperature, air current and ventilation
will also cause the source of light to vary.
2)When the source of light
is
received too early by
the light receiver, the precision of the mefer will be
reduced. Always keep the cover of the light receiver
in
its place. Avoid to allow the light receiver to be
come overloaded or avoid to mput high source of
light when testing is being conducted at low
illumination.
3)The mark set for referencing the testing of source
of light is located at the right top end of the light
recieving ball plane.
4)When the meter is turned on and the light receiver
cover is put in its place, 000 should be indicated by
LCD, However, if the voltage of the battery varied
and the low battery sign"ö" is still not yet indicated
it, will easily prevent zero from being recovered
when the meter is being switched on 0 ADJ should
then be adjusted to turn lt back to zero be fore
measurement should be started.
5)When low battery sign"~"is indicated, the
batteries should be renewed.lf zero cannot be
recovered after the battery has been renewed,
Please adjust 0 Addition so as recover zero.
6)When the meter is not in use, please keep the
cover of the light receiver in its place to avoid the
sensor from wearing out.
7)When it is not in use for a bong time, please take
the batteries away. And avoid to keep lt in a place of
high temperature and humidity.
