1.0 Introduction
The ETS-Lindgren HI-3638 ELF/VLF Electric Field Meter provides full
ELF/VLF (extremely low frequency/very low frequency) capability.
The HI-3638 covers MPR
bands I and II for Swedish
low-emission standards, plus
meets test requirements for
IEEE 1140-1994
(IEEE standard for the
measurement of electric fields
from video display terminals).
(Tripod not included)
The HI-3638 is useful in low field intensity measurements such as video display
terminals (VDTs) and computer monitors, as well as higher field environments
such as power transmission lines and industrial locations.
The HI-4416 Digital Readout/Control Unit is included with the HI-3638 and
provides an optically isolated, full control digital readout for quick and easy
measurements in any sensor orientation. An optional HI-4413P Fiber Optic
Modem allows for a serial interface.

humidity and moisture, oils from the human body, and debris from the connectors
they plug into. Always handle connectors and cables with care, using the
following guidelines.
Before performing any maintenance, disconnect
the fiber optic cables from the unit and turn off
power.
When disconnecting fiber optic cables, apply the
included dust caps to the ends to maintain their
integrity.
Before connecting fiber optic cables, clean the
connector tips and in-line connectors.
Before attaching in-line connectors, clean them
with moisture-free compressed air.
Failure to perform these tasks may result in
damage to the fiber optic connectors or cables.
