1 Safety Instructions
1.1 Safety Instructions for the Device
Use the measuring instrument only according to the operating instructions.
Do not replace any parts and do not modify this product without prior and written
consent by AGSYS. Do not service this device. Return the device to AGSYS
magnet systeme GmbH or to your local supplier for repair and maintenance to
ensure that all safety features remain.
Handling malpractice may result in damage to the device and possibly to injuries or
death of persons.
Do not dispose of this device in normal household garbage. Contact the
manufacturer for the proper disposal of this device.
Use only appropriate magnetic field probes for this measuring device.
Observe the labeling of the device before connecting a magnetic field probe.
Do not use the device in explosive environments or near to inflammable gases or
vapors.
Environmental Conditions:
This instrument has been designed for the use in rooms with low condensation. See
technical data.
1.2 Safety Instructions for Measuring Probes
agnetic measurements should only be done in areas with a maximum voltage of
60V DC, 30V AC R S. The magnetic field probes are not electrically insulated.
Please ensure that the probe holders and the housing are connected to protective
earth.
If you work in environments with voltages beyond 60V DC, 30V AC R S or 42V
peak, act with particular caution because of electric shock hazard.
For measurements in high magnetic fields, observe the risks which might occur
through strong magnetic fields.

2 Brief Introduction
easurements with the gaussmeter utilize the Hall effect as principle of
measurement. A Hall sensor is a symmetric current-carrying semiconductor. A
magnetic field running perpendicular through this element generates an asymmetry
on the chip and thereby creates an output voltage which, at first approximation, is
proportional to the product of magnetic field strength and forced current. For
higher magnetic field strengths, this correlation is no longer linear. This effect is
automatically compensated in the device. Thus, the gaussmeter measures the
magnetic flux density at a point with a high local resolution. It only measures those
components of the magnetic flux density which run perpendicularly through the
sensor.
2.1 Preparing a Measurement
For measurements you need to connect a measuring probe.
A suitable measuring probe can be connected via the 8 mm socket on the top of the
device. Each measuring probe is individually calibrated. The calibration data are
stored in the probe memory. When a measuring probe is plugged in or changed,
these parameters will be read automatically.
2.2 unning a Measurement
After switching on the device, the actual measured value is shown continuously. In
addition to this, the display shows further information on the device status, the
selected measuring range as well as the measuring mode.
• The measuring range, the physical display unit and the measuring mode can be
adjusted in the set-up menu.
• After setting the desired measuring range and unit, insert the probe into the
magnetic field. Especially for heterogeneous magnetic fields, such as they
appear on the surfaces and edges of magnets, pay attention that the measured
magnetic flux density strongly depends on the distance and position. Further
take into consideration that the magnetic field component is only measured in
one direction so that tilting the measuring probe might lead to an error.

2.3 Measuring Unit
The gaussmeter shows measuring values in physical units of the SI-system and of the
Gauss-CGS system (preferably used in North America).
You can adjust the unit in the set-up menu.
2.4 Selecting the Measuring ange
You can select from four measuring ranges in the set-up menu.
The lower left area of the display shows the upper limit of the selected range.
If the measured value exceeds the limit of the selected
range, the display shows
-OL- (Overload) instead of
the measured value.
