Firmware-Update - Gigahertz Solutions NFA 30M Operating Manual

Made in Germany
If the high pass is set at 50 Hz, this only refers to the broad band read-
ing or recording as it reduces the influence of movement induced field
components. For full information, the frequency components of sinus-
oidal waves at exactly 16.7 Hz are still recorded separately and can be
shown with the help of the NFAsoft.
If the filter is set, it is therefore not unusual for the summary indication
"All3D" to be smaller than the indication for 16.7 Hz, as the signal com-
ponents at 16.7 Hz are not integrated in the total sum of "All3D".
Furthermore, the signals of the different frequencies are added up
quadratically, which in turn means that the result of simply adding the
individual signals will also differ from the sum of "All3D". (For more in-
formation on this matter see chapter 9).

8 Firmware-Update

The firmware is the meters operating system and stored in its CPU 7 . If
you keep the "Mode"-key pressed while switching on the meter, you
will be shown the currently active firmware revision number.
The most up-to-date revision can always be downloaded from our
homepage (menu item "Downloads").
Procedure for the Update:
Download the respective zip-file from our homepage. Unzip and copy
the new "FIRMWARE.NFA"-file onto your SD memory card without
changing the name.
If need be, overwrite any old versions on the card, as only one
"FIRMWARE.NFA"-file should be on the card. It should NOT be renamed. It can be de-
leted from the card after the update.
Lock your SD memory card with the small switch on the left side of the
card. Insert SD card into your powered-off NFA. Switch on your NFA.
The display will show "CodE", the frequency LEDs will gradually
change from green to red during the update process. Then all LEDs will
turn off except for the status LED. As soon as the status LED turns
green, the update process is completed (this will take a few seconds
only).
Do not use any switches and especially do not switch off
the meter during the update process!
Don't forget to unlock the SD-card afterwards!

Please differentiate: With „NFAsoft" the firmware can be configured and the user set-
tings stored in the file „CONFIG.NFA". This has nothing to do with the firmware itself.
