6.2.2 Adjusting the backlight
The intensity of the backlight can be changed using the "backlight” menu.
Note:
Backlight intensity: it should be as bright as required. A backlight that is too bright
reduces the useful life of the display.
6.3 Display - Loss of communication
If communication with a Modbus RS485 digital sensor is lost, the parameter display, e.g. oxygen
in mg/L for an OPTOD sensor, will flash until communication is restored.
