1.0 Introduction
The ETS-Lindgren HI-4000 Hazard Measurement System introduces
fiber optic technology for the acquisition of data from electric and magnetic fields.
The use of fiber optic cables for data transfer minimizes perturbation during field
measurements.
The heart of this system is the HI-4416 System Readout. This fiber optically
isolated remote readout/control can be paired with any one of the ETS-Lindgren
lines of electric and magnetic field probes to provide a wide range
(10 kHz to 40 GHz) of field measurements.
Standard features of the HI-4416 System Readout include data logging, a
recorder output, and a custom Liquid Crystal Display (LCD) with bar graph. The
data log feature captures up to 150 field readings for later review. The recorder
output provides a DC voltage proportional to the indicated field value. All
selection and control functions are input via the front panel keypad's membrane
switches; this keypad is configured in a matrix, allowing access to twelve
functions.
The HI-4416 uses an ASCII character string for communication with the probe in
both directions. See Appendix C: HI-4416 Operating Protocols for details of the
data format.
The HI-4416 System Readout may be used in conjunction with many
ETS-Lindgren probes. For a current list please contact ETS-Lindgren Customer
Service.
