6.2.6 Auto-Dimming Configurations
The SRM industrial monitor features an auto-dimming LCD that can automatically adjust
the backlight brightness according to the ambient light. If the auto-dimming function is
turned on, the backlight turns brighter when the ambient illuminance is high. The backlight
dims automatically when the ambient brightness level is low.
The SI unit of illuminance is “lux”. Lux measures the intensity of light.
Table 6-2 lists the
