12. Calibration

     Calibrates the device. There are five
     functions.
     For a remote-seal transmitter, calibrate
     with the height set to 0 meters.
      -- Correct zero input: Calibrates zero
         input by equalizing input pressures
         of HP and LP.
      -- Correct LRV: Calibrates zero point
         (LRV).
      -- Correct URV: Calibrates span (URV).
      -- Restore factory settings: Return to
         the factory default calibration data (
         available for versions B.6 - B.F).
      -- Reset corrections: Discards
         calibrations.
