Brüel & Kjær offers services ranging from training and calibration to troubleshooting and repair of instruments.

For details see: Service

The analyzer can update the software by itself.
Note: This is for updating the software with the newest version available from the Brüel & Kjær web-site. The languages already installed will be updated as well, but you cannot install new languages or licenses - to do this use BZ-5503.

Tap on the "?" (help) button at the bottom of the screen of the instrument, then tap About and the link "Check for updates on the web...".
Tap the "Check for Updates" button to check for new updates. This will connect to the Brüel & Kjær update server - if a new software version is available the build version will be displayed and you can start or regret the update (you will be warned, if the new version requires a new license). If no newer version is available than the one already installed, then you will be told so and the update is terminated.

If you choose to update, then the analyzer will start downloading the new software on the CF- or SD-Card already inserted in the analyzer (required). You need at least 100 MByte of free space on the memory card. Depending on the speed and quality of the internet connection, this can take from a few minutes to several hours. If the connection is lost, then the download will automatically continue when connection is established again.
Note: The analyzer can continue measuring during the download period.

When download is complete, then measurement is paused, normal use of the instrument is prevented, connections to the instrument are terminated and the upgrade of the instrument will start. This will take 10-15 minutes and the analyzer will reboot when finished.
Note: Any unsaved Logging data will be saved and the analyzer is ready to use again.

If you need to reboot the instrument, you can click the button below.
Note: Please make sure that an ongoing measurement is stopped and saved. Rebooting will delete unsaved data; however, for Logging and Enhanced Logging the data might be saved during the reboot.

The web-site on the instrument will be available again within 2-3 minutes.
