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

4 Switches / Push-Buttons /
Connector
4.1 On / Off switch ("Power")
"On" = Measurement in process. When measuring, logging
is not automatically activated. Briefly press "Log" until the
status LED turns green to activate parallel logging. You can
switch back to "On" without interrupting the logging pro-
cess.
"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 meas-
urement is underneath the "Y" of the coordinate
system printed on the meter faceplate. Value re-
cordings will be axis specific.
4.3 AC/DC-input
AC/DC = combined AC/DC-input
As soon as an external sensor is connected to the device, its
signal is automatically displayed in mV and recorded, if re-
quired.
AC: A displayed value of 2000 corresponds to "1V
DC: +/- 0.1 to 1500 mV, i.e. with an HF59B connected and
in the coarse measuring range (scaled to 1V), the device
1
Note: The AC functionality has not yet been tested. The information produced
by the frequency decomposition of a demodulated pulsed HF signal will, of
course, not provide any really useful data.
