When the format of the file system has been accepted, then the speed of the device is tested. The test writes data to the device and measures the writing speed. The test takes less than a minute.
If the speed test is successful, then you can proceed using the device, otherwise you should use another memory device or try reformatting the device (if not done already).
Problems with Storing or Recalling Data
If you experience problems in storing or recalling data on memory devices, you can check and repair the integrity of the file system on the device or even re-format it, by doing the following:
1) Insert the memory device in the correct slot of the connector panel of the analyzer.
2) You will be notified that a device has been inserted – select Yes to change the default measurement path to it.
3) Tap > Explorer.
4) Tap to go up folder levels until you have reached the topmost level with a list of the available memory devices.
5) Tap on the name of the device (not the icon) to get a list of available commands.
6) Select Check and Repair to start the procedure. If any errors are found in the file system, they are fixed. When finished, you will be informed whether the device was OK or that errors have been fixed.
✐
Please note: The checking procedure can take several minutes, depending on the size of the device.To format a memory device:
Caution: All data on the device will be erased during the formatting process.
Do not remove the device or switch off the analyzer during the procedure – this might damage the file system and data and make the device unusable.
7) Select Format to start the formatting procedure.
✐
Please note: • The formatting procedure can take several minutes – depending on the size of the device• The read/write performance of SD and CF memory cards and USB sticks varies a lot. The performance depends on the manufacturer of the memory device, the type of device, the size of the device, how much it has been used, how fragmented the memory is, and even the day of production of the device. Two ‘identical’ memory devices can have a different performance because the manufacturer has changed the internal technology without notice.
• The cards delivered by Brüel & Kjær have all been tested for their read/write performance in the analyzer and can be used for the applications available in the analyzer. If you need more (or other) types of memory devices, please consult your local Brüel & Kjær representative.
💡
Hint: In general, you should select devices aimed for the industrial or professional photographer market.✔
Best Practice: Remember to regularly re-format the device (especially before a long unattended measurement) – this will ensure the best performance of the device.8) Select Test Speed, if you want to check the device’s file speed.
9.4.3 Battery Pack and Recalibration of Battery Charge Indicator
The software keeps the capacity of the battery pack updated. Over time the total capacity of the battery pack decreases. If you find that the Time Remaining estimate (tap the Battery icon to get this information) does not match the real time remaining (for example, the analyzer switches off automatically because of lack of power while the Time Remaining estimate indicates at least ½ hour), then you should manually re-calibrate the capacity of the battery pack. This is done using the following method:
1) Drain all the power from the battery:
a) Switch the analyzer on.
b) Disconnect external power.
c) Disconnect the analyzer from the PC.
d) Set > Preferences > Power > Standby After to Never.
e) To drain the battery faster, set Backlight On to Always (same menu) and select the maximum level of display backlight (tap Backlight at the bottom of the screen).
f) Leave the analyzer until the analyzer switches itself off 2) Charge the battery fully (at least 10 hours):
a) Connect the Mains Power Supply ZG-0426 to the analyzer.
b) Switch the analyzer on (and leave it on) and remember to reset the Standby After and Backlight On to your preferred settings.
c) Tap the Battery icon for the battery condition. This will indicate ‘Calibrating Battery’ initially. Let the battery charge until the battery charge indicator just below the power socket starts flashing green (G1 – 3 analyzers) or changes from red to green (G4 analyzers) and the ‘Calibrating Battery’ indication disappears from the pop-up window.
9.4.4 Touch Screen
If tapping with the stylus on the screen seems to be getting more inaccurate, you can adjust the touch sensitive screen, as follows:
1) Tap > Preferences > Display.
2) Tap Adjust Touch Screen and follow the on-screen instructions.

9.4.5 Reset Options Reset Button
Caution: Unsaved data or setups will be lost when you reset the analyzer.
If your analyzer stops responding to pushbutton presses, or taps, reset and reboot the analyzer by pressing the Reset button (located on the connector panel – see section 2.2) with the stylus.
If you still experience problems, try resetting your analyzer as described below.
Analyzer Reset
1) Reset the analyzer to a default/factory installed state.
For G1 – 3 analyzers, you will reset the analyzer to a default state, where the user is set to 2250Light and the project template is set to Sound Level Meter. The existing Sound Level Meter project template will be overwritten, as will the preferences for the user. To reset the analyzer to the default state:
a) Press and hold the Power-on pushbutton for at least five seconds (powers off).
b) Press and hold down the Manual Event 2 and Save pushbuttons while switching on the analyzer. The display in Fig.9.3 will be shown.

c) Press the Accept pushbutton to restore factory firmware and settings.
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 always use the latest available.
2) (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 log in 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 analyzer connected to the PC via Micro USB Cable AO-1494 (G4 hardware) or Mini USB Cable AO-1476, or a modem/LAN connection. Please consult the online help included with the BZ-5503 software for instructions on how to configure the analyzer.
Re-installing Software (G1 – 3 analyzers)
If the analyzer still does not work normally after performing the ‘Analyzer Reset’ procedure, then the software might need to be re-installed. This can be done in two ways:
1) If the connection to Measurement Partner Suite BZ-5503 works with the analyzer connected to the PC using a USB cable, then the software can be re-installed and re-configured through the USB cable. Please consult the online help included with the BZ-5503 software for instructions on how to re-install software on the analyzer.
2) If the connection to the PC does not work, then you need a CompactFlash® card (size at least 64 Mbytes) and a CF card reader for the PC. You can then use Measurement Partner Suite BZ-5503 to update the CF card with the necessary files. Please consult the online help included with the BZ-5503 software for instructions on how to update a CF card with installation files for the analyzer.
Power off the analyzer and insert the CF card in the CF slot on the analyzer. Then press and hold down the Manual Event 2 and Save pushbuttons while switching on the analyzer. The Maintenance Mode initial screen will be displayed, and then within a few seconds the screen shown in Fig.9.4 will appear.
Press the Accept pushbutton to update the software. This will take approximately 5 minutes.
Caution: Do not remove the CF-card while updating the software!
When the software has been updated, you will get the option of resetting to the default settings.
If the problem still persists, contact your local Brüel & Kjær representative.
