1 Description
ExpoM - ELF is a personal ELF magnetic field exposure meter for frequencies from DC up to 100kHz.
Features include four selectable bands (DC
– 1 kHz, DC – 10 kHz, DC – 100 kHz and higher field
strengths from DC to 1 kHz), GPS based outdoor localization and Wi-Fi connectivity. The built-in
Wi-Fi interface allows to stream the measurement data to an Android based device for real-time
display. ExpoM - ELF is a measurement module of the ExpoM exposure measurement platform and
can be extended by additional measurement devices and Smartphone Apps.
2 Case and Interfaces
2.1 Overview
The standard enclosure of ExpoM - ELF provides basic water (IP 64) and shock protection of the
device. The most important elements and controls of the device are shown in Figure 1. The magnetic
field sensors (1) are located at the front of the device about 15 mm underneath the arrows
identifying the orientation of the three measurement axes. The Multi-color LED (2) is the main
activity indicator of the device. The marker button (3) can be used to highlight specific events during
a measurement.

Marker button (3), Micro-USB interface (4), Charging indicator LED (5), ON/OFF switch (6)
A micro USB interface (4), a charging indicator LED (5) and the ON/OFF switch (6) are located on the
lower side of the case.
Important Note: ExpoM-ELF is delivered with a protective rubber cover on the Micro-USB receptacle.
It is recommended to always put the cover on the USB interface when no cable is plugged in. This
prevents unintentional electrostatic discharges (ESD) from disturbing ongoing measurements and
minimizes wear and tear of the contacts.
