The Sekonic L-308X or L308X-U ( The -U is for US only) has no way to turn off the auto power off after 4 minutes.
To save battery capacity, the meter will automatically turn off 4 minutes after the last button is pressed.
All settings and measurements are saved in memory even after the meter has automatically turned off. When the power is turned ON, they will be displayed again.
