3.4 Preparing for E-field measurements
3.4.1 Measurement setup
For EFA-300 only
The E-Field Unit is used to measure electric fields.
Unlike measurements of magnetic fields, electric field measurements are
easily influenced by persons or objects in the vicinity of the sensor.
The complete EFA-300 measurement setup for electric fields includes:
• The E-Field Unit fitted on a tripod
• The Basic Unit
• A fiber optic cable for connecting the E-Field Unit to the Basic Unit
Figure 3-4 E-Field Unit measurement setup
The E-Field Unit is a stand-alone instrument that takes care of all
processes, measurements and result storage. The EFA-300 Basic Unit
serves only as a remote control unit in this setup, and can be used for other
measurements once the settings have been made.
Table 3.1 shows the various functions of each part of the measurement
setup.
