If the analyzer now functions normally, you should install the software package of

your preference as described in section 9.2. Brüel & Kjær recommends that you

2) (for all hardware versions) If the analyzer now functions normally, define your preferred

settings in the Preferences screen, adjust the touch screen again and make necessary

changes to Setup (all accessed via the Main Menu ).

If you experience problems selecting another template or you login as another user, then note

which step causes the problem. You might need to delete/reconfigure the templates or users.

To delete/reconfigure templates or users, use Measurement Partner Suite BZ-5503 with the

Cable AO-1476, or a modem/LAN connection. Please consult the on-line help included with

the BZ-5503 software for instructions on how to configure the analyzer.

Re-installing Software (Hardware Versions 1 –3)

If the analyzer still does not work normally after performing the ‘Analyzer Reset’ procedure,

1) If the connection to Measurement Partner Suite BZ-5503 works with the analyzer connected

the USB cable. Please consult the on-line help included with the BZ-5503 software for

instructions on how to re-install software on the analyzer.

2) If the USB connection to the PC does not work, then you need a Compact Flash card (size
