Feldmeter FM10

Fieldmeter FM10

The field strength measurement device with innovative technique and revolutionary design in shirt-pocket format

  • simultaneous display of the electric and the magnetic field strength
  • isotropic measurement of magnetic fields
  • potential-free and potential-related measurement of electric fields
  • frequency range from 10 Hz up to 400kHz
  • resolution from 1 nT bzw. 0.1 V/m without switching the measurement range
  • peak-hold display and limit value alarm
  • optional with data-logger for long term and single point measurement including the software FM-Data
  • optional with voltage output for connection to oscilloscope and spectrum analyzer

Innovative and multi-functional

The Fieldmeter FM10 is an innovative new development that combines wide function diversity with an easy and intuitive operation on the basis of a powerful microcontroller technique.

Product highlights are the isotropic magnetic field strength measurement and the frequency range up to 400 kHz with a resolution of 1 nT and 0.1 V/m without the need of switching the measurement range.

Moreover, the Fieldmeter FM10L/LS supplies an integrated data logger with 1 GByte data storage and different storage modes.

Multiple measurement functions

Due to different measurement probes, the Fieldmeter FM10 is highly talented for electromagnetic fields.

The FM10 multi-purpose measurement probe supports a fast omni directional measurement of the magnetic fields. In addition the probe BS13 for measurement of isotropic magnetic fields is available.

For electric fields different measurement probes are available:


Wide frequency range

In dependence of the measurement probe a frequency range from 10 Hz up to 400 kHz is available.

With the integrated filter functions band pass 16.6 Hz, high pass 50 Hz and 2 kHz single frequency ranges can be selectively measured.

High resolution without switching

The Fieldmeter FM10 provides a measurement dynamic of 20,000 nT and/or 0.1 V/m in merely one measurement range each. Annoying switching between ranges or auto-ranging functions are a thing of the past.

Multi-functional display

On the rich in contrast and illuminated display the electric and magnetic field strength are indicated parallel, using a fast sample rate of 0.25 seconds.

Moreover, the X, Y and Z-parts of the magnetic field strength are displayable as seperated single values.

As an acoustic display the sound generator produces a signal proportional to the field strength.

Diverse functions

The Fieldmeter FM10 delivers some extra functions: an acoustic alarm is activated as soon as the adjustable limit values are exceeded. The peak-hold function displays even shortest peak values of the field strength. Auto-power-off prevents the battery from discharging. Optionally, four alternating voltage outputs are available.

Powerful data logger

The data logger of the Fieldmeter FM10L/LS has a 1 GByte storage capacity and a real-time clock for an accurate time and date assignment to each measured value. The sample rate is adjustable between 0.25 seconds and 1 minute.

The logger provides two operation modes: for long-term measurement the continuous mode, for spatial recording the single spot mode.

In addition, a parallel recording of the frequency ranges band pass 16.6 Hz und high pass is possible.

The transfer of the measured values and a clear setting of the FM10 functions are done via PC using a fast USB-interface. The functional software FM-Data serves to edit and document the measured values.

Managing measured data with FM-Data

The scope of delivery of the field meter with data logger FM10L/LS contains the program FM-Data. This program is constantly developed to adapt the needs of our customers. This service is available to you in the form of free of charge updates at any time!

The FM-Data enables the user to display the device settings of the Fieldmeter FM10L/LS, adjust setting like measurement interval or limits and transfer the new setup to the FM10L/LS.

FM-Data provides a clear management of the data storage of the Fieldmeter FM10L/LS. The stored data sets are displayed and can be loaded or deleted.

The data set window shows some information like the start and the end of the record, the sample interval and filter functions, as well as the minimum and maximum values plus the 95th percentlile. With the help of the mouse the measurement value and the time stamp of each sample can be called up in the diagram.

Important occurrences in the record can be displayed enhanced in the diagram by performing a zoom.

Dialogue windows enable the user to make own comments on the respective data set and to each measured point regarding a single point record. The edited data sets can be printed as a measurement protocol or as a diagram.

Moreover, an export function to include the readings in other applications such as chart and database programs is supported.

Additionally, the storage of the measurement diagrams as a graphic data is possible.
