Switches / Push-Buttons / Connector - Gigahertz Solutions NFA 30M Operating Manual

4 Switches / Push-Buttons / Con-
nector
4.1 On / Off switch ("Power")
"On" = Standard Measurement Setting
Allow some seconds for self-testing until measurement starts automati-
cally. LEDs are activated for full information during manual measure-
ments. They remain activated when you start logging by shortly switch-
ing to "Log" until the Status-LED is lit green and then back to "On".
"Log" = Logging / long term recording.
4.2 Tesla/Gauss Switch
This switch allows to select the display unit for the magnetic field – the
selection is indicated by the LEDs.
The isotropic point of the magnetic field measurement is un-
derneath the "Y" of the coordinate system printed on the
meter faceplate. Value recordings will be axis specific.
4.3 AC/DC-input
AC/DC = Combined AC/DC-Input
The moment you connect an external sensor, its signal will
automatically be displayed in mV and logged if required. ("Mode"
switch is set to "Auto". Protected against overvoltage).
AC: A displayed value of 2000 corresponds to an AC signal of

"1V ".
RMS
DC: It can linearly display and log signals from +/- 0.1 to +/-

1500mV, i.e. with an HF59B connected and set to coarse (adjust to
1V), the values recorded will be between 1µW/m² and approx.
30,000 µW/m². The value will be displayed in mV
For logging RF please make sure to remember the settings of the con-
nected HF-Analyser, as they will not be registered by the NFA. You
may use the audio note feature for that.
1 For all measurement ranges, even when using an attenuator or amplifier, NFAsoft of-
fers a comfortable conversion tool. The random noise will make it impossible to
properly display or record measurement values below 0.1µW/m², though.
