How barometric pressure affects measurement accuracy

Barometric pressure influences measurement calculations in Divesoft analyzers. This article explains how pressure compensation works and how it may affect measurement accuracy.

Possible causes

  • Barometric pressure compensation enabled

  • Changes in ambient pressure

  • Altitude differences affecting baseline calculations

Explanation

Divesoft analyzers use an internal barometric sensor to compensate measurement calculations based on ambient pressure.

Changes in atmospheric pressure or altitude may slightly influence calculated values. This behavior is normal and ensures that measurements remain accurate under varying environmental conditions.

If the barometric sensor is functioning correctly, the device automatically adjusts calculations without user intervention.

What to check

  • Ensure the analyzer has been powered on long enough to stabilize to ambient conditions.

  • Avoid rapid pressure or altitude changes immediately before calibration or measurement.

  • Perform calibration under stable environmental conditions.

When to contact service

If measurement values appear significantly incorrect and barometric pressure readings seem abnormal or inconsistent, please contact an authorized Divesoft Service Point for further diagnostics.
