-A INTRODUCTION

GENERAL
DESCRIPTION

The SERIES-9900 gaussmeter represents the latest developments in the
science of measuring magnetic flux density using the Hall effect. The unit is
available in three configurations capable of processing a single channel
(Model 9901), two channels (Model 9902) or three channels (Model 9903) of
magnetic field information. Either steady-state (dc) or alternating (ac) fields

can be measured. When matched with the appropriate F.W. Bell fourth-
generation Hall generator probe, fields as low as 10 pG (0.0011.1T) or as high
as 2.9999 MG (299.99 T), at frequencies up to 50 kHz, can be measured with
extreme accuracy and 4-3/4 digit resolution.

The SERIES-9900 features PEAK HOLD, AUTORANGING, CLASSIFIER and

RELATIVE operation, auto ZEROing, GAUSS or TESLA readout, digital and
bargraph representation, diagnostics and remote operation with an IEEE-488
(GPIB) instrumentation bus and an RS-232 communications port. All
information is displayed on an illuminated graphics liquid crystal display (LCD).

The gaussmeter employs a menu-driven format to allow the user to program
all aspects of gaussmeter operation with ease and speed. Each gaussmeter
channel is completely and independently programmable.

I-B FUNCTIONAL DESCRIPTION

Figures I-A and I-B depict the SERIES-9900 front and rear panels,

respectively. The gaussmeter is housed in a standard 6.87" high x 17.67"

wide x 16.18" deep cabinet featuring pop-up feet for tabletop use and

(optional) brackets for rack mounting.

legends ("0"=OFF, ''1"=ON).

Recessed double-wall Mu-metal chamber
used to shield the probe from stray magnetic

fields during the PROBE ZERO operation.
Attenuation is 80 dB in a 300 G field.
