3.0 OPERATION
NOTE: The HI-3603 is enclosed in a rugged aluminum
extruded case for protection of its internal circuitry.
Because of the nature of its intended use, the field
sensor extends from the readout module. The structure
of the sensor is a multilayered printed circuit board. It is
well secured internally to the aluminum case and has a
tough polyester covering but is exposed to greater
potential for physical damage because of its size and
location. Use care in handling the HI-3603 to avoid
damaging the sensor by striking it against objects or
applying excessive force to the sensor paddle. When not
in use, keep the HI-3603 in its protective case where the
sensor paddle is properly supported.
START UP
Membrane switches are used for controlling the HI-3603's
operation. The switch keypads are activated by gently pressing
on the center of the pad with a finger tip. Do not use hard or
pointed objects to operate the switch keypads.
Turn the unit ON, the default measurement condition is Magnetic
Fields. The custom LCD readout displays the units of measure in
addition to the observed value. A Bargraph display is provided
along the top of the LCD window. This display is an analog
approximation of the currently displayed digital value as a
percentage of the full-scale range. The BarGraph input is
unfiltered for fast response when searching for peak fields.
