1. About this Manual
This manual describes the installation, operation and maintenance of the Mag-03 range of three
axis magnetic field sensors. It should be read in conjunction with the product brochure (DS0013)
which can be found on the product page of the Bartington Instruments at: www.bartington.com.
Details of the enclosures, mounting, connector dimensions, connector pin allocation and the
position of the sensing elements relative to the enclosure are given in outline drawings on the
product page.
See Application Note AN0045: ‘Magnetic Units and Measurements’, available from Bartington
Instruments, for important information about magnetic field measurement units.

3. Introduction
These compact, high performance sensors with integral electronics provide measurements
of static and alternating magnetic fields in three axes. The sensors, also described as
magnetometers, convert magnetic flux density, measured in three axes, into a bipolar analogue
voltage. Analogue output voltages Vx, Vy and Vz vary linearly with magnetic flux density.
The analogue output is positive for conventional flux direction, South to North, in the direction
of the arrow shown on the label for each axis; i.e. the maximum positive output will be obtained
from any axis when the arrow points towards magnetic north along the total field vector. The
