There are two possible types of calibration:
• Offset Adjusts the measurement by a fixed amount
• Sound Velocity Adjusts speed of sound, and changes the measurement
calculations
Do Offset calibration at any steady level, unless a Sound Velocity calibration is also done.
If both calibrations are done, then do Offset at a known high level, and Sound Velocity at
a known low level.
