use SANDISK cards! We have had a lot of bad experiences

Your PC will recognize the SD card as an external device
when connected by USB cable or inserted into a card read-

tionality of your operating system. Inserting the SD memory
card directly into the card reader of the PC will result in a 40
times faster data transfer than if using the USB cable

Please note: Do not remove the SD memory while the
NFA is running!

Charging Socket
Computer interface connection: Used for meter
configuration with NFAsoft. (USB 1.0) Please
connect and disconnect the USB-cable only
while the NFA is switched off!
Please note: for the time being the USB connection works for windows
and Linux only!

Charging Socket
For the connection of external DC sources:
External supply: 12 V battery or 12 V DC power
supply unit is sufficient to keep the instrument
operational for long term data logging, but will
not recharge the battery.
Charging: 15 to 18 V DC battery or AC adaptor is required to
charge the instrument. Measurements or recordings parallel
to the charging procedure are technically possible, but not
specified, therefore not to be recommended.

In order to make use of this speed advantage, your SD card reader needs to be
specified „SDHC“, which is standard for units built 2008 or later. For older units
inexpensive adaptors are available.
