Measuring Ranges

The FM 302 can be used with all AS-active-probe in the ranges of µT, mT- and Tesla.

The device has three sensitivity ranges of x1, x10 and x100:

  • has influence on the display as well as on the analog-output
  • this results in three sensitivity ranges for each AS-active-probe
  • sensitivity ranges depend on the sensitivity class of the used AS-active-probe

Display Units

displayed unit can be switched

  • Tesla
  • Gauss
  • A/m (ampere per meter)
  • A/cm (ampere per centimeter)
  • Oersted

Calibrated Analog Output

The Teslameter FM 302 comes with a calibrated analog output.

  • analog voltage signal at BNC-connector
  • with full accuracy and full bandwith of teslameter and AS-active-probe

The transfer factor of the analog output is determined by the sensitivity class of the active-probe in use and the selected amplification-factor of the Teslameters FM 302. More details can be found in Empfindlichkeitsklassen (german language) .

USB Inteface

Via the USB interface the Teslameter FM 302 can be controlled and measurement data can be read.

  • driver creates a virtual serial port
  • control is done with ASCII-based commands
  • can be used with own software

A complete documentation of the commands can be found in the PDF Icon operating manual (page 41 ff).

Control Software

Included in delivery is a control software for the Teslameter FM 302.

The control software provides the following functionality:

  • Access to all settings
  • Displaying the current measured values
  • Logging of measured values (continually or after pressing a key)
  • Oscilloscope-like graphical displaying of the measured values
  • Comparator-like display of adjustable tresholds
