Switches / Push-Buttons / Connectors - Gigahertz Solutions NFA 1000 Operating Manual

4 Switches / Push-Buttons / Connectors

4.1 On / Off switch ("Power")
"On" = Standard Measurement Setting
LEDs and acoustic signal remain activated for manual measurements
"Log" = Logging / long term recording
All LEDs and the acoustic signal are deactivated to save battery life during data log-
ging. This is the mode in which the instrument is most precise.
"Off" = Device is off
4.2 Field Selection for 3D Measurement
M = Magnetic field measurement (3D)
3D
The isotropic point or magnetic field sensors are below the coordinate
Y
system printed on the meter faceplate. The dominating axis is indicated
X
by a red LED next to the display.
Z
XYZ = Axis indication
Here, the NFA 1000 will show either the magnetic or the electric field in its three in-
dividual components depending on the field type from which the switch was set to
"XYZ", whereas the NFA 400 will only show the individual components of the mag-
netic field. Press the 'Mode >' button to switch from one axis to the other. Please
see chapter 4.9 for details to this or to the automated scrolling.
E / Ey = Potential-free E-field measurement
3D
(NFA1000) (NFA400)
The field sensor pairs for the X-, Y- and Z-axis (directions correspond to the imprint)
are situated within the meter close to the housing. For a proper measurement the
meter has to be set up more than 12 inches away from any metal objects on an in-
sulated "holder" (accessory PM1) or held with an insulated rod (accessory PM4s).
Also cables or probes must not be connected during this measurement setting. In
the case of an erroneous configuration, the display will indicate "Err." until the con-
figuration is corrected or the setting is changed to magnetic field measurement. The
measuring person should avoid hectic movements and keep a distance of at least
1.5 m to the object of measurement.
