Page 3: Introduction
Helmholtz HM-2 torque coil, all types of coils or coil probes can be connected to the instrument. The FLUX-CHECK 250 fluxmeter has a very high input resistance of 33 kΩ, so that the measuring error is negligible when connecting any coil probes, even with high internal resistance. -
Page 4: Warnings And Hazards
UIDE • First connect the probe cable to the coil and the instrument. • Switch on the FLUX-CHECK 250 with the red on/off button. • An automatic zero adjustment is performed when the instrument is switched on. There must be no magnet in the coil. -
Page 5: General Information On Measuring Units
NFORMATION ON EASURING UNITS Four different values can be determined with the FLUX-CHECK 250 fluxmeter. The four values have different units and are therefore not comparable. These values are included separately in the statistics so that a minimum/maximum/average value can be analyzed. -
Page 6: Magnetic Flux Density (Fld)
The flux density can be displayed in A/cm and mT. The factor between A/cm and mT is 1.256 (as a rule of thumb: 4 A/cm ~ 5 mT). Measured magnetic flux density values are displayed in memory and statistics with the abbreviation FLD. List-Magnetik GmbH EN FLUX-CHECK 250 2025-03.docx... -
Page 7: Display Structure
The status bar shows the title of the current menu position and the battery status. The statistics area displays statistics for a series of measurements. If no memory batch is active, the List-Magnetik logo is displayed here. In the center is the measurement display with the current measurement and additional information about it. -
