Brightness meters are installed in cameras
so that the correct exposure time is set.
Our eye is so good at adjusting to different
brightness’s that we hardly notice the
difference. But your brightness meter with the
43
Dispositivo di misurazione della luminosita
light sensor and the LED strip is completely
objective and reliably indicates changes.
The corresponding programme is started with
the connection F-H.
Test the meter in a
completely dark
room. All LEDs will
only switch off,
if it is really
completely
dark. Shine
light from a torch
on the light sensor
from different distances.
The brighter the light reaching the sensor,
the longer the lit-up LED indicator will be.
Compare the brightness in different rooms
and outside in bright daylight.
