Pulsed Magnetic Field Standard library
The pulsed magnetic field standard menu offers a list of standards of edition 1 (2001) and edition 2 (2016).
The standard name has the character:
[Standard Family], [Standard number], [year])
The standard IEC 61000-4-9 Ed2 (2016) requires
mandatory an 18
F capacitor, that is automatically
internal switched in the circuit to output HC

User Test Routines
The user can program, save and recall his own specific user test routines, created by himself.
The extended menu offers various useful tests for testing and development.
SAVE AS USER TEST
Save the actual test as user test. The user defines the name of the test

Magnetic field as per IEC 61000-4-9
Pulse magnetic fields are generated by lightning strokes on buildings and other metal structures including aerial
masts, earth conductors and earth networks and by initial fault transients in low, medium and high voltage
electrical systems. In high voltage sub-stations, an impulse magnetic field may also be generated by the
switching of high voltage bus-bars and lines by circuit breakers.
A surge generator as specified in IEC 61000-4-5 is used to generate a short circuit current with the wave shape of
8/20
s. The waveform used is defined in Figure 3 of IEC 61000-4-5.
