2 Measurement methods

2.1 Notices prior to measurement

Warning
1. Do not use the light meter in environments full of dusts or having gas
2. Do not use the light meter for measurement in the place with high
temperature and high humidity.
3. Do not use the light meter in environments with intense infrared or
ultraviolet rays!
Tips
1. The opto-sensor of this meter is designed by simulating the sensitive
curve of light obtained through human eyes. The spectral coverage is
between 320mm and 730mm. When it is used for measurement within
the infrared range, there will be a large data deviation.
2. The opto-sensor is calibrated by common electric incandescent lamp
reading number may be different for the spectrum of other lamps.
3. The reference level of light source test is at the top of the spherical
surface illuminated.
4. The optical detector should expose to light for 2 minutes before
measurement.
5.
should be avoided.

2.2 Action principles

2.2.1 Concepts of illuminance scales

One lux (lumen) indicates the illuminance got on a surface of one square
meter, all points of which are one meter from a uniform source of one
candela.
One foot-candle (Fc) indicates the illuminance got on a surface of one
square foot, all points of which are one foot from a uniform source of one
candela.

2.2.2 Unit conversion for illuminance scales

1 Fc = 10.764 lux
1 lux = 0.09290 Fc

2.2.3 Conversion formula for illuminance and light intensity

E = I / r
During the measurement, the minimum distance between the luminous
surface of light source and the opto-sensor should be more than 15 times
greater than maximum size of the luminous surface (or opto-sensor).
Prompt for manual range switching mode.
Prompt for data hold mode.
The analog bar shows the current measurement value information.
The digit shows the current measurement value information.

I --- Light intensity of the light source(Unit: cd)
r --- Distance from the luminous surface of light source to the
optical detector (Unit: mt.).
