Appendix B-5
Configuration Menu –Atmospheric Pressure Offset
The menu option <P> displays for RBR loggers that will record pressure. Selecting this option
allows you to zero the atmospheric pressure either automatically or manually. This sets the
current ambient pressure on the RBR logger to zero scale at the surface so that the logger reading
reflects the pressure from below the surface.
Figure B-5: Option <P> Atmospheric Pressure Calculation
This is typically only necessary if deploying in a location that is not near sea
level (for example, a high mountain lake).
Figure B-6: Automatic Atmospheric Pressure Offset
Typing a calibrates the pressure automatically. Automatic calibration takes the average of several
pressure readings for the atmospheric pressure at the sampler’s current location.
