You can use the meter to measure illuminance with the built-in light
sensor. The sensor is located near the mark "Lux" on the top of the
meter (Figure 2).
Measuring Intensity of Illumination
Set the range switch to "
×Lux
" position.
Point the light sensor to the light source to be measured in order
that the light can reach the sensor through the small white
cover of the sensor (Figure 5).
Multiply the reading by 10. The result is the measured value.

The illuminance measurements are affected by the direction
of light, the location of the sensor, and the distance between
the sensor and the light source.
While performing measurements, make sure that the light to
be measured is not blocked by the user's body.
