Gauss-/Teslameter
the condition that exists during factory calibration. The greater the deviation from orthogonality
(from right angles in either of the axes), the larger is the error of the reading. For example: A 5°
variance on any one axis causes a 0.4 % error, a 10° misalignment induces a 1.5 % error.
3.8 Remote Operation
The FH 52 is equipped with a USB interface. This can be used to transfer measurements to a
computer and the FH 52 can be remotely controlled.
For communication with the FH 52, suitable software must be installed to the computer. At the
time of creation of these operating instructions Magnet-Physik supplies software for the
following operating systems: Microsoft Windows
hardware driver is not necessary; a diver included with Windows
systems are configured to search the internet for hardware drivers automatically by default,
which can take several minutes. If the search has been started once, it should not be interrupted.
On the web page of Magnet-Physik, www.magnet-physik.de, a software package named
"FH 52 Software" is available for free download. This contains the following components:
• FH 52 Teslameter: a simple program for displaying and saving readings and for remote
control of the most important functions of the FH 52.
• MagnetPhysik.FH52.dll: a .NET assembly that you can use in your own programs
created with Microsoft C#, Visual Basic .Net or National Instruments LabVIEW
capture readings or to control the FH 52.
• Programming examples in Microsoft C#, VB.net and a description, how to use the
FH 52 with National Instruments LabVIEW
More information can be found in the documentation inside the software package.
Furthermore you can purchase the program "MagDat" that has among others the following
features:
• Display of readings, continuous recording and saving in various file formats.
• Remote control of almost all functions of the FH 52.
• Simultaneous display and recording of the readings from multiple FH 52 devices and
other measuring instruments made by Magnet-Physik.
3.9 Operating Principle
The operation of the field strength meter is based on the Hall Effect. This is named after the
American physicist Edwin Herbert Hall, who explored the effect in 1879.
The sensor element, the so-called Hall generator, is made of a semi-conducting material. The
schematic construction is shown in the following figure.
