Gigahertz Solutions NFA 1000 Operating Manual page 13

4.7 USB-Socket
USB 1.0 computer interface connection: Used for meter configuration
with NFAsoft. Please take care to have the NFA switched off when
connecting or disconnecting the USB-cable!
4.8 Charging Socket
For the connection of external DC sources:
External supply: 12 V battery or 12 V DC power supply unit is sufficient
12-15 V
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.
The instrument comes with an AC adaptor (Euro mains plug!), which can be
switched either to 12 or to 15 V. Measurements or recordings parallel to the charg-
ing procedure are technically possible, but not specified, therefore not to be rec-
ommended.
4.9 „Mode" and „Rec." - Buttons for
Navigation and Voice Recording
In connection with the "Mode"-switch and the switch for selecting the field type, the
"Mode" and "Rec." keys form part of the many special functions of this device.
They are not needed for a simple measurement of the 3D magnetic field.
"Mode" = Change of display mode or "Step ahead"
The configuration of the "Mode"-button is context sensitive.
If the "Mode"-button on the left is on "Auto", the NFA recognizes external probes
connected to it, and displays their corresponding values. If a probe is not connected
to the instrument, it displays the selected ("primary") field type.
 Press and release the "Mode>" button to switch from the primary to secondary
measurement fields. The secondary or background measurement field is indicat-
ed by a quick flashing LED corresponding to the unit-LED.
