F.W. BELL Model 7030 Gauss/Tesla Meter Instruction Manual
Section 1 - Introduction 1-5
GENERAL
DESCRIPTION
(Continued)
A separate BNC connector, labeled “Vector Summation”, provides a
corrected output signal that is proportional to the resultant magnitude
of the three channels vector sum.
Standard full scale output ranges are 3V, 10V, 3V
RMS
, and 10V
RMS.
An
adjustable full scale up to 9.9V or 9.9V
RMS,
in increments of 0.1V, is
also available. These outputs may be connected to a voltmeter,
oscilloscope, recorder, or external analog-to-digital converter.
Analog Filters
A low pass filter is available for each channel that may be set to pass
frequencies only below 50kHz, 5kHz, or 500Hz. The instrument can
automatically select the best filter setting based on the present flux
density being measured. The filters affect both the displayed reading
and the analog outputs.
Field Classifiers
The “Classifier” function allows the user to define a lower and upper
limit of flux density that can be used to quickly determine the status of
a magnetic field. The instrument will indicate visually whether the
field is below, within, or above the pre-defined limits. The same
information is provided in the form of general purpose switch closures
available at a standard 15 pin “D” type female connector.
Remote Operation
Remote operation is supported through a standard 9-pin “D” RS232
serial port connector or through an IEEE-488.2 (GPIB)
instrumentation bus. The 7030 can be fully configured and flux
density readings and other information can be acquired by a remote
computer or PLC. The commands follow widely accepted protocols
established by the IEEE-488.2 and SCPI-1999 standards.
Accessories
The instrument is shipped with a “zero flux chamber” used for
shielding the probes from unwanted fields during zeroing. A sturdy
carrying case is provided for the zero flux chamber, probes, and this
manual.
