4 Switches / Push-Buttons / Connector

4.1 On / Off switch ("Power")

"ON" = Measurement in process. When measuring, logging is not automatically acti-

vated. Briefly press "Log" until the status LED turns green to activate parallel log-

ging. You can switch back to "On" without interrupting the logging process.

"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 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 required.

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 logs measurement values from 1 to 30,000 µW/m²;

the display shows mV.

For logging high frequencies please make sure to remember the settings of the con-

nected HF-Analyser, as they will not be registered by the NFA.

Note: The information produced by the frequency decomposition of a demodulated pulsed HF signal will, of

course, not provide any really useful data.

For all measurement ranges, even when using an attenuator or amplifier, NFAsoft offers a comfortable conver-

sion tool. The random noise will make it impossible to properly display or record measurement values below

0.1µW/m², though.
