Magnetic field antenna
The correction factor of the magnetic field antenna type MFC 1000 series is
0.87
. This means that an antenna
current of 100 A will generate a magnetic field of 87 A/m in the center of the antenna (1m x 1m Antenna). To
achieve 100 A/m an antenna current of 114.94 A is necessary.
This factor is also an important value which shall be entered to the software. Depending on the dimension and the
design of the antenna this factor will change.
Magnetic field antenna MFC 1000.1
Plugs for connect MFC 1000.x
The magnetic field antenna has two different types of connectors.
-
Two sets of parallel safety banana connectors for the range of 30 A/m and an optional set of connectors
for higher currents.
-
The high current 14mm connectors are used with the MFT 100 only. The cables are part of the transformer.
Fix and unlock mechanical parts
By lifting the grip, the free movement of the
serration
toothing enables the clamping lever to swing into
the desired position.
The grip moves into its original position when
released
