Brief Introduction
Introduction Introduction
Introduction
Measurements with the gaussmeter use the Hall effect as a measuring principle. A
Hall probe is a symmetric semiconductor impressed by current. A magnetic field
running vertically to this element generates an asymmetry on the chip and thereby
creates an output voltage that, as a first approximation, is proportional to the product of magnetic field strength and the forced current. For higher magnetic field
strengths this dependency is no more linear. This effect is automatically compensated in the device. The gaussmeter thus measures the magnetic flux density locally.
The sensor only captures the component of the magnetic flux density which runs
perpendicularly through it.

• Insert the measuring probe into the measuring field after adjusting the requested measuring range and the requested unit. Especially for inhomogeneous
magnetic fields, such as they occur on the surface and edges of magnets, keep
in mind that the measured magnetic flux density depends very largely on the
distance and the position. Further pay attention that the magnetic field component is measured in one direction only, so that a tilting of the measuring probe
may lead to an error.

The measurement is based on the diflection of charge carriers in a magnetic field inside a conductor. For this reason the Lorentz force is the basis for measuring a magnetic flux density. If you set a voltage between the beginning and the end of a flat
electrical conductor, the carriers move with a speed of

measured that is ideally proportional to the magnetic flux density. Only the part of
the flux density is effective which runs perpendicularly through the flat side of the conductor.

of the Sensitivity of the Sensitivity
of the Sensitivity
There are several influences for the flux-density dependence of the sensitivity:
The carrier mobility depends on the flux density. This influence generally brings about
a negative α
Hall
and is irrelevant for the used Hall sensors.
More important is the geometry of the used Hall sensors. The lamellar structure creates a geometry-based field dependence of the sensitivity.
The non-homogeneous distribution of the current density in such a structure is the
cause of this effect.
Already in field-free cases, the current distribution on the Hall element is complex.
This entails a lowering of S0 and has an influence on the field dependence of the
sensitivity.
A complex real-time correction of the handheld gaussmeter HGM09 compensates for
the inherent non-linearities of the used Hall probes and guarantees a very stable
zero point.

of the Cross Current Resistance
The complex current distribution is the cause of the resistance of a Hall probe. Current components which, just as the Hall voltage, run perpendicularly to the direction
of the current feed, cause a diverted Hall effect. For the current source this effect results in a flux density modulated resistor.
The device must have a sufficiently high dynamic for the measurement with fast magnetic pulses, to be able to compensate this effect. The handheld gaussmeter HGM09
is optimized for this operating case.

The used Hall probes contain a very small active semiconductor area ranging at approx.

Due to the high local resolution, the near-surface measurement with magnets may lead
to misinterpretations because of the large field-strength gradients.
Figure 3 Flux Line Characteristics of NdFeB Induction Disks
Figure 3 shows an NdFeB magnet with a material remanence of 1400mT. In this example the magnetic disk has a thickness of 5mm with a diameter of 20mm. The magnet is
supposed to be measured in 1mm distance from the surface.

Figure 4 Field Strength Pattern of NdFeB Induction Disk
The diagram in Figure 4 represents the measurement with a Hall probe which is moved
in parallel to the surface of the magnet with a distance of 1mm distance to the measuring surface.
A minimum of the flux density emerges in the center of the magnet. Here approx.
230mT are measured. Due to the locally changing working points on the radius of the
magnet, the flux density increases toward the outside. In the center the magnet carries
the highest magnetic load in air and therefore provides the lowest flux density.

Positioning and Direction
Since the measuring value is dependent on the position, an accurate and repeatable
measurement depends on the exact positioning of the probe during the measurement.
The measurement on the pole center of the magnet is most uncritical. When moving the
probe on the pole surface of the magnet, the measuring value hardly changes at first.
When changing the distance though, the measuring value varies considerably.

change the measuring value. For quality-related research it is essential to ensure the
positioning accuracy.
Since a Hall probe only records one field strength vector, the correct alignment relative
to the magnet is important.
Please be particularly careful when measuring at the zero point at pole transitions. By
slightly tilting the probe, you measure additional lateral field shares that seem to displace the zero passage.
In normal applications, a maximum flux density value is usually determined at a given
position. The measuring probe is placed in position and varied in location and direction
until the maximum is found. The device supports this measurement with the peak hold.

External Static Magnetic Fields External Static Magnetic Fields
External Static Magnetic Fields
Particularly in sensitive measuring ranges, an external static magnetic field, as e.g. the
Earth’s field, can already become clearly noticeable. These external magnetic fields lead
to a corruption of the measuring result.
To compensate external magnetic stray fields or asymmetries of the Hall probe, the device can be reset.
For this purpose please hold the measuring probe into a field-free area, e.g. a zero
Gauss chamber, or orient the measuring probe in a free field in east-west direction and
press the NULL
NULLNULL
NULL button for approx. 3 seconds. The device then carries out a null balance
automatically.
The values are stored so that this balancing has to be carried out only in seldom cases.
If the magnetic field is too high during the automatic balancing, the correction is stopped
with an error message.

USB Interface
The transmission of the measuring values and the entire gaussmeter control
are possible via the installed standard USB interface.
The interface is specified according to the USB (Universal Serial Bus) 2.0.
The interface is not insulated. Please note that the shielding of the measuring probes (e.g. the metallic handle) might be connected to the protective
conductor of your personal computer via this USB interface.
The device supports two USB device classes. On the one hand the HID
class. In this mode the data can be entered directly into any program. The
gaussmeter acts similar to the keyboard of a personal computer.
On the other hand, the device can be operated in the USB device class
CDC and thereby emulates a virtual serial interface on the personal computer or another processor. In contrast to the HID mode, the installation of
a driver on the processor becomes necessary here.
Via the virtual serial interface all functions and parameters of the device
can be set using the SCPI command, and the measuring values can be
read out automatically.

RANGERANGE
RANGE changes the range of the
measuring value.
More complex parameter settings can be made via menu functions in the setup menu.
The button functions in detail:
With this button you change the measuring range, the measuring unit
and the measuring mode (DC or AC fields). The exact function of this button depends on the settings in the setup menu. Further explanations, see
there.
Via NULL the displayed peak value is set to zero in the peak value meas-
uring mode.
If you press the button for approx. 3 seconds, the magnetic offset values
are compensated.
In the USB operating mode HID (keyboard) the current measuring values
are transmitted to the connected processor and can be entered into any
program.
This button has no function in the other operating modes. In the USB operating mode CDC (virtual interface), pressing this button can be read out
via an SCPI command.
To switch the device on and off, press the button for approx. 2 seconds.
If you press the button longer when switching on, the setup menu is called
up.

DC Field Measurements
When measuring DC fields, the gathered measuring values are integrated via a time
interval of 100 milliseconds. Influences of AC magnetic fields are thereby suppressed. This applies especially for interspersions of the AC network with a net frequency of 50 to 60 hertz.
The measuring values are emitted with positive or
negative signs respectively.
Alternatively, the magnetic field polarity can also be
displayed to (north/south). You can choose this by

analyzed continuously and the lowest or respectively
highest value are determined from it.
In this operating mode approx. 10 measurements per
second are carried out in high resolution. This enables
recordings of slowly changing field sizes. A typical application is the determination of
a maximum field strength value of a permanent magnet by manual positioning of the
measuring probe on the surface.
Reset the value via the NULL button.

Via the installed serial interface all functions of the gaussmeter can be piloted by a
controller (e.g. a personal computer). The interface can be used in two completely
different ways.
On the one hand the gaussmeter can write the data directly into any PC application.
In this KEYBOARD mode, the gaussmeter acts similar to a keyboard that is connected
to a personal computer. The measuring data are transmitted automatically on pressing the DATA
DATADATA
DATA button. A special installation of drivers is not necessary. This operating
mode works for computers based on Windows as well as for Linux operating systems or for Apple computers. The only requirement for the computer is that it has a
connection for keyboards based on USB 2.0. This operating mode is e.g. suitable for
filling out Excel sheets easily.
If you want to control the gaussmeter automatically and the connected computer is
supposed to actively carry out the data exchange, a connection via a virtual serial interface is possible. In this operating mode a USB compliant CDC connection is established. The gaussmeter acts like an additional serial interface for a user program.
However, in this case you must install a driver. For the standard Windows operating
systems the driver is included in the delivery.
The data transmission itself, i.e. the protocol, is defined in close connection to the
widely-used SCPI programming language for measuring devices.

The gaussmeter is connected to the computer via the USB interface. The device setting USB MODE is adjusted to KEYBOARD. The top right area of the display shows
KEYB.
The installation of a driver depending on the operating system is generally not required. The operating system solely has to support the HID (Human Interface Device)
device class according to USB 2.0. This is the case for standard computers under
Windows, Linux or Mac OS.
After starting a suitable program, e.g. Microsoft Excel, the measuring data can be
transmitted to the respective data fields by simply pressing the DATA
DATADATA
DATA button. The
decimal separator is selected automatically in dependence of the country version of
the computer.
The transmitted number of digits corresponds to the number that is monitored on the
device display. For normal measurements and fast peak value measurements a

Installation on the Computer
For the comprehensive operation on an external computer use the CDC device class
(Communication Device Class) of the USB specification. This communication class
defines a virtual serial interface on the connected computer. For the user program,
the gaussmeter turns out to be an additional serial interface. The operation can be
tested by simple terminal programs, as Hyperterm under Windows. Depending on
the operating system, the installation of a driver on the computer might become necessary. You find more detailed notes on this in the driver installation documents.

SCPI Language
The programming language SCPI (Standard Commands for Programmable Devices)
defines the way a measuring device (here the gaussmeter) can communicate with a
controller. The SCPI language uses a hierarchical structure. The command tree consists of root directory commands that are placed on top and several levels below
each root directory command. You have to specify the complete path to execute
commands of the lower levels.

Command Structure
The commands generally have a short and a long form. In the following descriptions,
the short form is set in upper case. The attached long form is set in lower case. Only
the characters of the short form are checked for syntactic correctness. Upper and
lower case spelling is not distinguished. The same is true for the parameters. A parameter is always emitted in long form and in upper case.
Example:
Command PROBe:POTEntialcoil:LENGth?
Send PROBe:POTEntialcoil:LENGth?
Send PROB:POTE:LENG?
Send PROB:POTEntial:leng?

If a colon is the first character of a command key word the next command code is a
command of the root directory. If a colon is written between two command codes the
colon entails a path to the next lower level of the current path of the command tree.
Command codes must be separated from one another by a colon. You can omit the
colon at the beginning of a command if the command is the first of a new program
line.

Query Commands
Commands Commands
Commands
The controller can send out commands at any time, however a SCPI device (here the
gaussmeter) will only answer, if it has expressly been instructed to do so. Only query
commands (commands that end with a question mark) prompt the device to send a
response. For queries, the device displays either measuring values or internal device
settings.
Note
If you send two query commands without having read the reply to the
first and thereupon try to read the first response, you might receive
some data of the first reply, followed by the complete second response. Therefore do not send any query command without having
read the reply beforehand. Commands and queries should not be
sent via the same program line. This might result in an overflow of the
raw data buffer, in the event that too many data are created.

Data Types
The SCPI data language defines different data formats that are used in the program
message and in the reply message. SCPI devices can normally accept commands
and parameters in different formats. In particular the numerical parameters can be
used very freely. Contrary to this general definition, the data formats are restricted in
some places here.

Numerical Parameters
Commands that require numerical parameters, accept the generally used decimal
notation of numerical characters including leading characters, decimal points and
leading zeros. The scientific notation is supported. The technical unit is preset for
most commands and will then not be transmitted. For some commands the unit is
part of the command being an additional parameter.
Example:

Boolean Parameters
Boolean parameters represent a single condition that is either true or untrue. As an
untrue condition the gaussmeter accepts "OFF" or "0". As a true condition the gaussmeter accepts "ON" or "1". If a Boolean setup is interrogated, the device always emits
"0" or "1".
Example:
:DISP:BARG ON

twice in a row without blank.

7.4.6 The SCPI Status Model
The SCPI Status ModelThe SCPI Status Model
The SCPI Status Model
The status system records different device conditions in several register groups. The
individual messages are grouped in the several registers. One bit of these registers is
related to one message respectively.
The measuring event register stores the messages that are relevant for the measurement. The data error register stores the error messages and the standard event register the SCPI standard messages.
7.4.6.1
7.4.6.17.4.6.1
7.4.6.1 Event Register
Event RegisterEvent Register
Event Register
The event register can only be read. The signal bits are set by the device but are not
deleted automatically.
Bits in an event register are deleted either by interrogation of this register (*ESR? or
e.g. :STAT:QUES:EVEN?) or by the *CLS command. When interrogating an event
register, the device emits a decimal value that corresponds to the sum of the binary
place values of all bits that are set in this register.
7.4.6.2
7.4.6.27.4.6.2
7.4.6.2 Release Register
Release RegisterRelease Register
Release Register
The individual bits of the assigned event registers are masked via the release registers. Only the released bits enter into the sum bit as an OR connection. The release
registers are read- and writeable. The release registers are not deleted by a query.
The *CLR command does not delete the release registers. The command
:STATus:PRESet deletes the release register for the error data. When interrogating an
event register, the device emits a decimal value that corresponds to the sum of the
binary place values of all bits that are set in this register. For setting the bits in a release register, a decimal value is transmitted that corresponds to the sum of the binary place values of all bits set in this register.
7.4.6.3
7.4.6.37.4.6.3
7.4.6.3 Sum Register
Sum RegisterSum Register
Sum Register
In the sum register the results of the event registers are summarized after the masking in the release register and assigned to individual bits. The deletion of the event in
the event registers also sets back the respective sum bit in the status register. Via the
release register of the sum register the individual sum bits can be re-merged to one
whole message service request.
