Test Modes are stored and managed in the Test Modes Library, which can be found in the FieldLab Desktop application (Free to download and use). Custom Test Modes can be added to multiple FieldLab devices.

When you edit a Test Mode in FieldLab Desktop, you must then sync it with each FieldLab device that has that Test Mode.

With FieldLab Desktop open on the computer, plug in the FieldLab with the provided USB cord and Power it On.


Go to the Devices screen and select the FieldLab you wish to Sync.

An orange dot will appear next to any Ralston Gauges that need to be Synced.


Select the Sync Button.


Select Done once syncing is complete.

Repeat Steps 1 through 4 for each FieldLab that requires Syncing.
