Can measurements recorded with the SONAPHONE without a predefined measuring point or inspection route be evaluated later in DataSuite?

Yes. Measurements can also be recorded with the SONAPHONE independently of an asset tree, measuring point, or inspection route.

These so-called unassigned measurements can subsequently be imported into the DataViewer in SONAPHONE DataSuite and analyzed there.

What is an unassigned measurement?

An unassigned measurement is recorded directly using a SONAPHONE app without first assigning the measurement to a defined measuring point via AssetExpert.

This can be useful, for example, for:

• spontaneous individual measurements,
• troubleshooting,
• initial inspections of an unknown system,
• comparative measurements,
• measurements outside a planned inspection route.

The measurement can then be saved and exported for further analysis.

How are unassigned measurements transferred to DataViewer?

Unassigned measurements are saved as ZIP archives using the corresponding app on the SONAPHONE.

According to the current documentation, DataViewer supports ZIP archives generated by:

• LevelMeter
• SteamExpert

The ZIP archive is first transferred from the SONAPHONE to the PC and then loaded into DataViewer using the Import Unassigned Measurements function.

A single ZIP archive or several ZIP archives can be imported at the same time.

Which data can be analyzed in DataViewer?

DataViewer provides various measurement and analysis information for a selected unassigned measurement.

This includes:

• time signal,
• level graph,
• spectrogram,
• frequency spectrum,
• selected key metrics,
• measurement metadata,
• photos,
• text notes,
• voice memos.

Up to eight key metrics can be selected for the diagram view.

The ultrasonic signal can also be played back audibly directly from the time signal or spectrogram.

Can measurement data be exported?

Yes. Measurement data can, among other options, be downloaded from DataViewer as a CSV file.

Screenshots of individual diagrams or the complete analysis widget can also be created.

Can an unassigned measurement later be assigned to a measuring point?

Yes, depending on the DataSuite version being used.

Unassigned measurements can be assigned to an existing asset tree or directly to an existing measuring point after analysis.

This makes it possible, for example, to take a measurement spontaneously and later assign it to the corresponding physical asset for further use together with its existing measurement history.

The function for assigning unassigned measurements is not included in SONAPHONE DataSuite - V.

When should DataViewer be used?

As a simplified guide:

• Measuring point and inspection route already exist: perform the measurement using AssetExpert and subsequently evaluate it in AssetData.
• Measurement was recorded spontaneously without a predefined asset structure: import and analyze the measurement in DataViewer.

DataViewer therefore enables flexible analysis of ultrasonic measurements without requiring a complete asset structure to be created before the measurement is performed.
