Calibrate Depth Sensor
You must calibrate the sensor if the depth does not show precisely 0.0m
on the OLED Display. Do so by pulling the Activation Switch until "Depth
calibrated" is written on the OLED Display. Now, the sensor will show 0.0
at the current pressure level.
Video Settings
This menu allows you to change the settings for the video mode. You can
select in which resolution and frame rate you want to record.
