8 Firmware-Update

The file: "firmware.nfa" is the meter's operating system stored in its internal
8
memory . As known from computer programmes, this software is subject to contin-
uous improvements and upgrade, and can be updated as described below. As also
known from computer programmes, a new version of an operating system is always
intensely tested prior to distribution, but errors may sometimes occur which are only
detected in the course of its use. For this reason, there are always two versions of
the firmware on the internal memory of the meter. One is revision 058 which has
been running without problems for many years, and should therefore be kept on the
meter memory for "emergency cases", the other is the latest revision at the point of
purchase, always with the a.m. risk.
Which firmware is active on your NFA?
If you press the "∨"-key while switching on the meter, you will for a short while be
shown the currently active firmware version (always with either the prefix "F" or "E".
In order to switch from one version to the other, please press both, the "∨"-key as
well as the "∧"-key at the same time while switching on the meter.
Procedure for the Update:
First make sure to have firmware version 058 active before starting the update pro-
cedure. This way you will always update the other version on your meter.
Copy the new "FIRMWARE.NFA"-file onto your SD memory card without changing
it.
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 deleted 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 up-
date 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 sec-
onds only).
Do not switch the meter off during the update process!
Please remember to unlock the SD-card after applying the new firmware!

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