: In the LMS mode, the flow and pressure units and cost-related settings are configured by an officer in the
LMS. When you download a survey to the OS 531, these settings are downloaded to the OS 531 along with other
survey data. If you spot a wrong setting, report it to your officer. After the officer updates the setting in the LMS,
the leak records that you have uploaded or will upload to the LMS will be updated and saved to the LMS database
based on the new setting.
