No, you do not need a license to use Diver-Office. For details, please refer to the end user license agreement that is shown during the software installation process, in the Help > About window or the Diver-Office EULA in PDF format.

What is the difference between Diver-Office and Diver-Field?

As the names suggest Diver-Office is an application for office use and Diver-Field is for field use.

Use Diver-Office to setup your monitoring projects and define the fieldwork that needs to be done, such as a site visit sequence, collection of Diver data and deployment of Divers. Use Diver-Field to carry out fieldwork and download Diver data. Once the data is collected, use Diver-Office to merge time series, barometrically compensate the Diver data to convert them into water levels. Finally, you visualize data including manual measurements and export data to MON, CSV or XLSX files for further use in third party applications.

Diver-Field assists you carrying out your tasks in the field and streamlines the workflow of fieldwork and support decision-making in the field. Diver-Field indicates the order to visit the monitoring locations and once at the site helps you to carry out predefined tasks such as downloading Diver datalogger data, collecting manual water level data and restarting the Diver.

What is the Diver-Tookit?

The Diver-Toolkit is the installation package that contains both Diver-Office and Diver-Field.

How do I find out what version of Diver Office I’m using?

In the main window click on Help and then select the About option to found out what version of Diver-Office you are using.

Database

Can I share the database on a network?

With Diver-Office you can share the database on a network. To use a database (filename VEI.db) in a folder other than the default folder (C:\ProgramData\DiverOffice) open the config file DiverOffice.exe.config located in the installation folder (by default: C:\Program Files (x86)\Diver-Office) with a text editor. Locate the key DatabaseFolder and change its value to the desired folder location, for example:

  • <add key=”DatabaseFolder” value=”Y:\DiverData”/>, where Y:\DiverData must be a valid network location.
  • <add key=”DatabaseFolder” value=”\\network_path\DiverData”/>, where \\network_path\DiverData must be a valid network location.

How can I backup/restore the database?

Diver-Office does not have a database backup/restore feature. The database file must be copied manually.

The database is a single file named VEI.db that is located in the database folder. The location of the database folder depends on the Windows version:

  • Windows 8/10: C:\ProgramData\DiverOffice
  • Windows 7/Vista: C:\ProgramData\Application Data\DiverOffice or C:\ProgramData\DiverOffice

Please note that the folder Application Data is a hidden folder.

To backup the database: Make a copy of the VEI.db file.

To restore the database: Copy the VEI.db file to the database folder.

If the previous steps did not work, please refer to the following document that outlines in how to backup/restore a Diver-Office database: Diver-Office Backup and Restore the Database

Barometric Compensation

How does the barometric compensation work?

When Diver-Office is installed there are also some example files installed. You can use these example files for an exercise on barometric compensation. Click here to download a pdf file of the exercise.

Which manual measurement is used for barometric compensation?

The most recent (date and time) manual measurement is used for barometric compensation.

Can I use a manual measurement for more than one barometric compensation?

No, the manual measurement can only be used for barometric compensation if it falls within the time span of both the Diver and Baro-Diver time series.

However, once a barometric compensation has been done a «calculated cable length» will appear in the Location settings window. Check the radio button for «calculated cable length» field and the result is that initial manual measurement will be virtually used for any following compensation.

Can I calculate the depth to water from the top of casing as a positive number?

Yes, you can. If you choose the center option of the barometric compensation Water level with respect to top of casing the water level will be negative if the water level is below the top of casing.

If you want to have the inverse, i.e. the water level is positive if the water level is below the top of casing, you must set the top of casing value in the Location settings tab to zero. Then you choose the right compensation method Water level with respect to vertical reference datum.
