          The HI-3604 Power Frequency Field Strength Measurement System is designed to assist in the evaluation of electric and magnetic fields that are associated with 50/60 Hz electric power transmission and distribution lines along with electrically operated equipment and appliances. Direct digital readout of field strength is provided by the instrument with the ability to read the meter remotely via a fiber optic remote control (Model HI-3616) which is available as an option. The HI-3604 finds applications in research and environmental field studies where knowledge of the strength of power frequency fields is required. It is designed to provide engineers, industrial hygienists and health and safety personnel with a sophisticated tool for the accurate investigation of power frequency electrical environments.

          The HI-3604 has two selectable sensors for measuring both electric and magnetic fields. The instruments' capabilities include data-logging, waveform output, full auto-ranging, and a custom Liquid Crystal Display (LCD) with a bar graph. All selection and control functions are input from a front panel membrane switch pad. True RMS (root-meansquare) detection assures accurate measurements of complex waveforms. The waveform output jack allows observation and evaluation of the actual waveform being measured. The data-logger feature captures up to 112 field readings for later review using front panel controls. Microprocessor technology is incorporated in the HI3604 to provide for automatic range changing (manual range changing may be selected) and automatic zeroing of the instrument.
