Allowed supply voltage drop-out:
100ms from min. 10V, return to min. 8V
Battery voltage measurement tolerance
2 % at 24V
Hint:
For the supply voltage less than 7V the backlight of the display is switched off.
Short-term voltage drops (e.g. during the engine cranking) do not affect the operation at all.
